I've installed Python 3.5 and while running
pip install mysql-python
it gives me the following error
error: Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)
I have added the following lines to my Path
C:\Program Files\Python 3.5\Scripts\;
C:\Program Files\Python 3.5\;
C:\Windows\System32;
C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC;
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC
I have a 64-bit Windows 7 setup on my PC.
What could be the solution for mitigating this error and installing the modules correctly via pip.
Your path only lists Visual Studio 11 and 12, it wants 14, which is Visual Studio 2015. If you install that, and remember to tick the box for Languages → C++ then it should work.
On my Python 3.5 install, the error message was a little more useful, and included the URL to get it from:
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
New working link.
As suggested by Fire, you may also need to upgrade setuptools package for the error to disappear:
pip install --upgrade setuptools
Binary install it the simple way!
Use the binary-only option for pip. For example, for mysqlclient:
pip install --only-binary :all: mysqlclient
Many packages don't create a build for every single release which forces your pip to build from source. If you're happy to use the latest pre-compiled binary version, use --only-binary :all: to allow pip to use an older binary version.
To solve any of the following errors:
Failed building wheel for misaka
Failed to build misaka
Microsoft Visual C++ 14.0 is required
Unable to find vcvarsall.bat
The solution is:
Go to Build Tools for Visual Studio 2017
Select free download under Visual Studio Community 2017. This will download the installer. Run the installer.
Select what you need under workload tab:
a. Under Windows, there are three choices. Only check Desktop development with C++.
b. Under Web & Cloud, there are seven choices. Only check Python development (I believe this is optional, but I have done it).
In cmd, type pip3 install misaka.
Note if you already installed Visual Studio then when you run the installer, you can modify yours (click modify button under Visual Studio Community 2017) and do steps 3 and 4.
Final note: If you don't want to install all modules, having the three below (or a newer version of the VC++ 2017) would be sufficient. (You can also install the Visual Studio Build Tools with only these options, so you don’t need to install Visual Studio Community Edition itself) => This minimal install is already a 4.5 GB, so saving off anything is helpful
As the other responses point out, one solution is to install Visual Studio 2015. However, it takes a few GBs of disk space.
One way around is to install precompiled binaries. The webpage Unofficial Windows Binaries for Python Extension Packages (mirror) contains precompiled binaries for many Python packages. After downloading the package of interest to you, you can install it using pip install, e.g. pip install mysqlclient‑1.3.10‑cp35‑cp35m‑win_amd64.whl.
I had the exact issue while trying to install the Scrapy web scraping Python framework on my Windows 10 machine. I figured out the solution this way:
Download the latest (the last one) wheel file from this link: wheel file for twisted package
I'd recommend saving that wheel file in the directory where you've installed Python, i.e., somewhere on the local disk C:
Then visit the folder where the wheel file exists and run pip install <*wheel file's name*>
Finally, run the command pip install Scrapy again and you're good to use Scrapy or any other tool which required you to download a massive Windows C++ Package/SDK.
Disclaimer: This solution worked for me while trying to install Scrapy, but I can't guarantee the same happening while installing other software, packages, etc.
After reading a lot of answers on Stack Overflow and none of them working, I finally managed to solve it following the steps in this question. I will leave the steps here in case the page disappears:
Please try to install Build Tools for Visual Studio 2017, select the workload “Visual C++ build tools” and check the options "C++/CLI support" and "VC++ 2015.3 v14.00 (v140) toolset for desktop" as below.
I had this exact issue while trying to install mayavi.
I also had the common error: Microsoft Visual C++ 14.0 is required when pip installing a library.
After looking across many web pages and the solutions to this question, with none of them working, I figured out these steps (most taken from previous solutions) allowed this to work.
Go to Build Tools for Visual Studio 2017 and install Build Tools for Visual Studio 2017. Which is under All downloads (scroll down) → Tools for Visual Studio 2017
If you have already installed this, skip to 2.
Select the C++ components you require (I didn't know which I required, so I installed many of them).
If you have already installed Build Tools for Visual Studio 2017 then open the application Visual Studio Installer then go to Visual Studio Build Tools 2017 → Modify → Individual Components and selected the required components.
From other answers, important components appear to be: C++/CLI support, VC++ 2017 version <...> latest, Visual C++ 2017 Redistributable Update, Visual C++ tools for CMake, Windows 10 SDK <...> for Desktop C++, Visual C++ Build Tools core features, Visual Studio C++ core features.
Install/Modify these components for Visual Studio Build Tools 2017.
This is the important step. Open the application Visual Studio Installer then go to Visual Studio Build Tools → Launch. Which will open a CMD window at the correct location for Microsoft Visual Studio\YYYY\BuildTools.
Now enter python -m pip install --upgrade setuptools within this CMD window.
Finally, in this same CMD window, pip install your Python library: pip install -U <library>.
Use this link to download and install Visual C++ 2015 Build Tools. It will automatically download visualcppbuildtools_full.exe and install Visual C++ 14.0 without actually installing Visual Studio.
After the installation completes, retry pip install and you won't get the error again.
I have tested it on the following platforms and versions:
Python 3.6 on Windows 7 64-bit
Python 3.8 on Windows 10 64-bit
Use this and save time
pip install pipwin
pipwin install yourLibrary
pipwin is like pip, but it installs precompiled Windows binaries provided by Christoph Gohlke. Saves you a lot of time googling and downloading.
And in this case pipwin will solve the problem
Error: Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)
Read more about pipwin and here they mention Microsoft Visual C++
I had the same problem when installing the spaCy module. And I checked the control panel, and I had several Microsoft Visual C++ redistributables installed already.
I selected "Microsoft Visual Studio Community 2015" which was already installed on my PC → "Modify" → check "Common Tools for Visual C++ 2015". Then it will take some time and download more than 1 GB to install it.
This fixed my issue. Now I have spaCy installed.
I had this same problem. A solution for updating setuptools
pip install -U setuptools
or
pip install setuptools --upgrade
Make sure that you've installed these required packages. It worked perfectly in my case as I installed the checked packages:
To expand on the answers by ocean800, davidsheldon and user3661384:
You should now no longer use Visual Studio Tools 2015 since a newer version is available. As indicated by the Python documentation, you should be using Visual Studio Tools 2017 instead.
Visual C++ Build Tools 2015 was upgraded by Microsoft to Build Tools for Visual Studio 2017.
Download it from here.
You will also require setuptools. If you don't have setup tools, run:
pip install setuptools
Or if you already have it, be sure to upgrade it.
pip install setuptools --upgrade
For the Python documentation link above you will see that setuptools version must be at least 34.4.0 for Visual Studio Tools to work.
Use the link to Visual C++ 2015 Build Tools. That will install Visual C++ 14.0 without installing Visual Studio.
I had the same issue. Downloading the Build Tools for Visual Studio 2017 worked for me.
I had exactly the same issue and solved it by installing mysql-connector-python with:
pip install mysql-connector-python
I am on Python 3.7 and Windows 10 and installing Microsoft Build Tools for Visual Studio 2017 (as described here) did not solve my problem that was identical to yours.
Just go to https://www.lfd.uci.edu/~gohlke/pythonlibs/ find your suitable package (whl file). Download it. Go to the download folder in cmd or typing 'cmd' on the address bar of the folder. Run the command :
pip install mysqlclient-1.4.6-cp38-cp38-win32.whl
(Type the file name correctly. I have given an example only). Your problem will be solved without installing build toll cpp of 6GB size.
To add on top of Sushant Chaudhary's answer:
In my case, I got another error regarding lxml as below:
copying src\lxml\isoschematron\resources\xsl\iso-schematron-xslt1\readme.txt -> build\lib.win-amd64-3.7\lxml\isoschematron\resources\xsl\iso-schematron-xslt1
running build_ext
building 'lxml.etree' extension
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
I had to install lxml‑4.2.3‑cp37‑cp37m‑win_amd64.whl the same way as in the answer of Sushant Chaudhary to successfully complete installation of Scrapy.
Download lxml‑4.2.3‑cp37‑cp37m‑win_amd64.whl from Lxml
put it in folder where Python is installed
install it using pip install <file-name>
Now you can run pip install scrapy.
I had the same exact issue on my windows 10 python version 3.8.
In my case, I needed to install mysqlclient were the error occurred Microsoft Visual C++ 14.0 is required. Because installing visual studio and it's packages could be a tedious process, Here's what I did:
step 1 - Go to unofficial python binaries from any browser and open its website.
step 2 - press ctrl+F and type whatever you want. In my case it was mysqlclient.
step 3 - Go into it and choose according to your python version and windows system. In my case it was mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl and download it.
step 4 - open command prompt and specify the path where you downloaded your file. In my case it was C:\Users\user\Downloads
step 5 - type pip install .\mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl and press enter.
Thus it was installed successfully, after which I went my project terminal re-entered the required command. This solved my problem
Note that, while working on the project in pycharm, I also tried installing mysql-client from the project interpreter. But mysql-client and mysqlclient are different things. I have no idea why and it did not work.
I had a similar situation installing pymssql.
pip was trying to build the package, because there were no official wheels for Python 3.6 and Windows.
I solved it by downloading an unofficial wheel from Unofficial Windows Binaries for Python Extension Packages.
Specifically for your case: MySQL-python
I just had the same issue while using the latest Python 3.6. With Windows OS 10 Home Edition and a 64-bit operating system.
Steps to solve this issue:
Uninstall any versions of Visual Studio you have had, through Control Panel
Install Visual Studio 2015 and chose the default option that will install
Visual C++ 14.0 on its own
You can use PyCharm for installing Scrapy: Menu Project → Project Interpreter → + (install Scrapy)
Check Scrapy in the REPL and PyCharm by import. You should not see any errors.
None of the solutions here and elsewhere worked for me. It turns out an incompatible 32-bit version of mysqlclient is being installed on my 64-bit Windows 10 OS because I'm using a 32-bit version of Python.
I had to uninstall my current Python 3.7 32 bit, and reinstalled Python 3.7 64 bit and everything is working fine now.
If Visual Studio is NOT your thing, and instead you are using VS Code, then this link will guide you thru the installer to get C++ running on your Windows.
You only needs to complete the Pre-Requisites part.
https://code.visualstudio.com/docs/cpp/config-msvc/#_prerequisites
This is similar with other answers, but this link will probably age better than some of the responses here.
PS: don't forget to run pip install --upgrade setuptools
This works for me:
pip install --only-binary :all: mysqlclient
I tried ALL of the above and none worked. Just before before signing up for the booby hatch, I found another reason for the error : using the wrong shell on Windows.
conda init cmd.exe
did the trick for me. Hope it may save someone else, too.
I was facing the same problem. The following worked for me:
Download the unofficial binaries file from Christoph Gohlke installers site as per the Python version installed on your system.
Navigate to the folder where you have installed the file and run
pip install filename
For me python_ldap‑3.0.0‑cp35‑cp35m‑win_amd64.whl worked as my machine is 64 bit and Python version is 3.5.
This successfully installed python-ldap on my Windows machine. You can try the same for mysql-python.
Look if the package has an official fork that include the necessary binary wheels.
I needed the package python-Levenshtein, had this error, and found the package python-Levenshtein-wheels instead.
I had the same problem. I needed a 64-bit version of Python so I installed 3.5.0 (the most recent as of writing this). After switching to 3.4.3 all of my module installations worked.
Python Releases for Windows
I had the same issue while installing mysqlclient for the Django project.
In my case, it's the system architecture mismatch causing the issue. I have Windows 7 64bit version on my system. But, I had installed Python 3.7.2 32 bit version by mistake.
So, I re-installed Python interpreter (64bit) and ran the command
pip install mysqlclient
I hope this would work with other Python packages as well.
TLDR run vcvars64.bat
After endlessly searching through similar questions with none of the solutions working.
-Adding endless folders to my path and removing them. uninstalling and reinstalling visual studio commmunity and build tools.
and step by step attempting to debug I finally found a solution that worked for me.
(background notes if anyone is in a similar situation)
I recently reset my main computer and after reinstalling the newest version of python (Python3.9) libraries I used to install with no troubles (main example pip install opencv-python) gave
cl
is not a full path and was not found in the PATH.
after adding cl to the path from
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.27.29110\bin\Hostx64\x64
and several different windows kits one at a time getting the following.
The C compiler
"C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.27.29110/bin/Hostx64/x64/cl.exe"
is not able to compile a simple test program.
with various link errors or " Run Build Command(s):jom /nologo cmTC_7c75e\fast && The system cannot find the file specified"
upgrading setuptools and wheel from both a regular command line and an admin one did nothing as well as trying to manually download a wheel or trying to install with --only-binary :all:
Finally the end result that worked for me was running the correct vcvars.bat for my python installation namely running
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat" once (not vcvarsall or vcvars32) (because my python installed was 64 bit) and then running the regular command pip install opencv-python worked.
I am on a windows 10 machine and recently moved from python 2.7 to 3.5. When trying to install lxml through pip, it stops and throws this error message-
building 'lxml.etree' extension
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
I have a working copy of VS 2015 installed. When I try to install the visual cpp tools through that link, it says that Microsoft Visual Studio 2015 is already installed on the machine. I also tried installing visual studio c++ 2015 redistributables, both 64 and 32 bit versions, but both of them say that there's another version of the product already installed.
typing set in the command prompt includes this -
VS140COMNTOOLS=C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\
Which means that the path is set.
This is probably the only resource I could find on SO, but the answer suggests rolling back to Python 3.4.3 from 3.5. Has anybody resolved problems of this kind?
Microsoft Visual C++ 14.0 is required (Unable to find vcvarsall.bat)
EDIT: I managed to install it using the precompiled binary (Thanks Paul), but I would still like to know what's causing this.
Have you checked that when you installed Visual Studio, you installed the C++ compiler? It seems like a silly question, but this is the mistake I made. Check by going into the setup for visual studio (Programs and features: Modify "Visual Studio 2015"), then under Programming Languages->VC++, make sure it's ticked.
Run pip install wheel
Download lxml from http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml, if your python version is 3.5 , download lxml-3.6.4-cp35-cp35m-win32.whl.
Run python -m pip install lxml-3.6.4-cp35-cp35m-win32.whl
As an update to the answer from #davidsheldon above, if you want to use Visual Studio Build Tools 2017 instead of 2015, it will work.
I found that the default install of the build tools stand alone was not enough, however, I added `VC++ 2015.3 ... toolset for desktop (x86,x64) and then python was happy:
I've found another solution to get through this:
Because I use anaconda python, so I use this code:
conda install -c conda-forge scrapy
I have same question with you! I found a way no need install vs2015,maybe,you just haven't install twisted.http://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted .download twisted --version（Twisted‑17.5.0‑cp36‑cp36m‑win_amd64.whl）(maybe win_amd32.whl if 64didn't work)，and run : pip PATH + filename
pip install C:\Users\CR\Downloads\Twisted-17.5.0-cp36-cp36m-win_amd64.whl
pip install Scrapy
I just install successful! good luck for you!
my step to insatll scrapy:
1.pip install wheel
2.pip install lxml
3.pip install pyOpenSSL
4.pip install Twisted (fault->do like above)
5.install pywin32 form : https://sourceforge.net/projects/pywin32/files/pywin32/Build%20220/
6.pip Scrapy (succesful)
Had the same problem and noticed that I had installed the 32bit version in a 64bit machine. All I did was uninstall the wrong one and install the right version and it worked fine.
Easiest way to achieve this, can be automated as it doesn't require user input:
python -m pip install https://download.lfd.uci.edu/pythonlibs/archived/lxml-4.9.0-cp311-cp311-win_amd64.whl
This will install the 64-bit version on your machine.
First:
pip install wheel
Second： go to http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml
and download proper wheel.
pip install the file you downloaded (.whl).
When tried to install Twisted for Python 3.6.3 it keeps on throwing a particular error :
building 'twisted.test.raiser' extension
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
Tried install the Visual-Cpp-build tools but its a massive 4 + gigs download so is there any other way to do it .. Also I have all the redistributable.
I also had the same problem
what I did is install it manually
got to https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted
and download suitable twisted version.
then
pip install Twisted-18.9.0-cp36-cp36m-win_amd64.whl
hope this solves for you too
Installing Scrapy on Windows can be a real struggle. Some strange errors can occur.
That's why the scrapy documentation recommands to use Anaconda for the scrapy installation. I think you should give it a try if you are working on Windows.
First you need to install Anaconda following this tutorial.
Then you just need to run this command conda install -c conda-forge scrapy
and you are good to go.
I was trying to install the bokeh Python package via pip but I was thrown this error:
error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat).
I fixed that error by installing Microsoft Visual C+ and installed successfully after that.
However, now I want to install bokeh inside my virtual environment which I created with virtualenv. My intent is to build a Flask app.
I got the same error again, but this time I have no idea what to do.
Any help would be greatly appreciated.
Try opening the MSVisual command prompt, and cd to your virtualenv directory. From there, try installing with pip.
You can also try updating pip, and setuptools in your virtualenv.
I fixed this problem, but I did quite a few things before I did, so I'm not quite sure how I fixed this part of it.
for future google users / stack overflow users.
I had a similar error, but I needed Visual C++ 14.0. This error popped up while trying to install a package while venv was running (with the activate.bat script already run)
apparently updating setup tools was the solution. And by that I mean, when I used pip to uninstall uninstalled SoundCard and re-ran setup.py for SoundCard, I received no more errors about v14.0 missing. (This was all with venv running).
I already had Visual C++ Redistributable 2015 v14.0 installed locally. But my venv couldn't find it.
Run this command to update setuptools.
pip install --upgrade setuptools
I updated from 28.8.0 to 41.1.0 but the linked comment below says36.2.7 worked for them.
If this worked for you, please give the comment below some love as well.

Use the link to Visual C++ 2015 Build Tools. That will install Visual C++ 14.0 without installing Visual Studio.
I had the same issue. Downloading the Build Tools for Visual Studio 2017 worked for me.
I had exactly the same issue and solved it by installing mysql-connector-python with:
pip install mysql-connector-python
I am on Python 3.7 and Windows 10 and installing Microsoft Build Tools for Visual Studio 2017 (as described here) did not solve my problem that was identical to yours.
Just go to https://www.lfd.uci.edu/~gohlke/pythonlibs/ find your suitable package (whl file). Download it. Go to the download folder in cmd or typing 'cmd' on the address bar of the folder. Run the command :
pip install mysqlclient-1.4.6-cp38-cp38-win32.whl
(Type the file name correctly. I have given an example only). Your problem will be solved without installing build toll cpp of 6GB size.
To add on top of Sushant Chaudhary's answer:
In my case, I got another error regarding lxml as below:
copying src\lxml\isoschematron\resources\xsl\iso-schematron-xslt1\readme.txt -> build\lib.win-amd64-3.7\lxml\isoschematron\resources\xsl\iso-schematron-xslt1
running build_ext
building 'lxml.etree' extension
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools
I had to install lxml‑4.2.3‑cp37‑cp37m‑win_amd64.whl the same way as in the answer of Sushant Chaudhary to successfully complete installation of Scrapy.
Download lxml‑4.2.3‑cp37‑cp37m‑win_amd64.whl from Lxml
put it in folder where Python is installed
install it using pip install <file-name>
Now you can run pip install scrapy.
I had the same exact issue on my windows 10 python version 3.8.
In my case, I needed to install mysqlclient were the error occurred Microsoft Visual C++ 14.0 is required. Because installing visual studio and it's packages could be a tedious process, Here's what I did:
step 1 - Go to unofficial python binaries from any browser and open its website.
step 2 - press ctrl+F and type whatever you want. In my case it was mysqlclient.
step 3 - Go into it and choose according to your python version and windows system. In my case it was mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl and download it.
step 4 - open command prompt and specify the path where you downloaded your file. In my case it was C:\Users\user\Downloads
step 5 - type pip install .\mysqlclient‑1.4.6‑cp38‑cp38‑win32.whl and press enter.
Thus it was installed successfully, after which I went my project terminal re-entered the required command. This solved my problem
Note that, while working on the project in pycharm, I also tried installing mysql-client from the project interpreter. But mysql-client and mysqlclient are different things. I have no idea why and it did not work.
I had a similar situation installing pymssql.
pip was trying to build the package, because there were no official wheels for Python 3.6 and Windows.
I solved it by downloading an unofficial wheel from Unofficial Windows Binaries for Python Extension Packages.
Specifically for your case: MySQL-python
I just had the same issue while using the latest Python 3.6. With Windows OS 10 Home Edition and a 64-bit operating system.
Steps to solve this issue:
Uninstall any versions of Visual Studio you have had, through Control Panel
Install Visual Studio 2015 and chose the default option that will install
Visual C++ 14.0 on its own
You can use PyCharm for installing Scrapy: Menu Project → Project Interpreter → + (install Scrapy)
Check Scrapy in the REPL and PyCharm by import. You should not see any errors.
None of the solutions here and elsewhere worked for me. It turns out an incompatible 32-bit version of mysqlclient is being installed on my 64-bit Windows 10 OS because I'm using a 32-bit version of Python.
I had to uninstall my current Python 3.7 32 bit, and reinstalled Python 3.7 64 bit and everything is working fine now.
If Visual Studio is NOT your thing, and instead you are using VS Code, then this link will guide you thru the installer to get C++ running on your Windows.
You only needs to complete the Pre-Requisites part.
https://code.visualstudio.com/docs/cpp/config-msvc/#_prerequisites
This is similar with other answers, but this link will probably age better than some of the responses here.
PS: don't forget to run pip install --upgrade setuptools
This works for me:
pip install --only-binary :all: mysqlclient
I tried ALL of the above and none worked. Just before before signing up for the booby hatch, I found another reason for the error : using the wrong shell on Windows.
conda init cmd.exe
did the trick for me. Hope it may save someone else, too.
I was facing the same problem. The following worked for me:
Download the unofficial binaries file from Christoph Gohlke installers site as per the Python version installed on your system.
Navigate to the folder where you have installed the file and run
pip install filename
For me python_ldap‑3.0.0‑cp35‑cp35m‑win_amd64.whl worked as my machine is 64 bit and Python version is 3.5.
This successfully installed python-ldap on my Windows machine. You can try the same for mysql-python.
Look if the package has an official fork that include the necessary binary wheels.
I needed the package python-Levenshtein, had this error, and found the package python-Levenshtein-wheels instead.
I had the same problem. I needed a 64-bit version of Python so I installed 3.5.0 (the most recent as of writing this). After switching to 3.4.3 all of my module installations worked.
Python Releases for Windows
I had the same issue while installing mysqlclient for the Django project.
In my case, it's the system architecture mismatch causing the issue. I have Windows 7 64bit version on my system. But, I had installed Python 3.7.2 32 bit version by mistake.
So, I re-installed Python interpreter (64bit) and ran the command
pip install mysqlclient
I hope this would work with other Python packages as well.
TLDR run vcvars64.bat
After endlessly searching through similar questions with none of the solutions working.
-Adding endless folders to my path and removing them. uninstalling and reinstalling visual studio commmunity and build tools.
and step by step attempting to debug I finally found a solution that worked for me.
(background notes if anyone is in a similar situation)
I recently reset my main computer and after reinstalling the newest version of python (Python3.9) libraries I used to install with no troubles (main example pip install opencv-python) gave
cl
is not a full path and was not found in the PATH.
after adding cl to the path from
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.27.29110\bin\Hostx64\x64
and several different windows kits one at a time getting the following.
The C compiler
"C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.27.29110/bin/Hostx64/x64/cl.exe"
is not able to compile a simple test program.
with various link errors or " Run Build Command(s):jom /nologo cmTC_7c75e\fast && The system cannot find the file specified"
upgrading setuptools and wheel from both a regular command line and an admin one did nothing as well as trying to manually download a wheel or trying to install with --only-binary :all:
Finally the end result that worked for me was running the correct vcvars.bat for my python installation namely running
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat" once (not vcvarsall or vcvars32) (because my python installed was 64 bit) and then running the regular command pip install opencv-python worked.
