I installed Kivy successfully. But got error when run a program which is the module "Jnius" is not found.
For Jnius, I installed Cython, jdk, jre and add the path variables. Then got error to install the visual studio for C++.
While installing the Visual studio, the installing window get closed automatically. Then, I choose another option to install Microsoft Visual C++ Compiler for Python 2.7. Installation is successfull.
But again got error:
I ran into something like something like that today when i tried to install a package in pip command and the when i tried to install it binary it worked:
pip install --only-binary :all: jnius
you can try this and see if it's any help

I'm trying to install a package on Python, but Python is throwing an error on installing packages. I'm getting an error every time I tried to install pip install google-search-api.
Here is the error how can I successfully install it?
error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/
I already updated that and have the latest version of 14.27 but the problem is throwing the same error.
Go to this link and download Microsoft C++ Build Tools:
https://visualstudio.microsoft.com/visual-cpp-build-tools/
Open the installer, then follow the steps.
You might have something like this, just download it or resume.
If updating above doesn't work then you need to configure or make some updates here. You can make some updates here too by clicking "Modify".
Check that and download what you need there or you might find that you just need to update Microsoft Visual C++ as stated on the error, but I also suggest updating everything there because you might still need it on your future programs. I think those with the C++ as I've done that before and had a similar problem just like that when installing a python package for creating WorldCloud visualization.

You can also follow these steps here:
Select: Workloads → Desktop development with C++
Then for Individual Components, select only:
Windows 10 SDK
C++ x64/x86 build tools
You can also achieve the same automatically using the following command:
vs_buildtools.exe --norestart --passive --downloadThenInstall --includeRecommended --add Microsoft.VisualStudio.Workload.NativeDesktop --add Microsoft.VisualStudio.Workload.VCTools --add Microsoft.VisualStudio.Workload.MSBuildTools
Reference:
https://www.scivision.dev/python-windows-visual-c-14-required
2020 - redist/build tools for Visual C++
silent installs can be done using the following two commands :
vs_buildtools__370953915.1537938681.exe --quiet --add Microsoft.VisualStudio.Workload.VCTools
and
VC_redist.x64.exe /q /norestart
Upgrade your pip with: python -m pip install --upgrade pip
Upgrade your wheel with: pip install --upgrade wheel
Upgrade your setuptools with: pip install --upgrade setuptools
Close the terminal
Try installing the package again.
I tried everything and then finally, downgrading from python 3.10 to 3.9 is what worked. (I noticed it in this comment, but it is a bit different scenario: https://stackoverflow.com/a/70617749/17664284 )
check if no older version of Microsoft Visual C++ are installed. If so uninstall them.
I encounered the above-mentionned problem when using virtualenv. Using conda environment instead solved the problem. Conda automatically installs vs2015_runtime which compiles the wheels with no problem.
In addition to the verified answer by #ice bear, just make sure to reboot your system after downloading and installing the latest visual studio build tools. And then the error you might be getting would go!
Tried Prason's approach. Also tried the fix suggested here
conda install -c conda-forge implicit
pip install --upgrade gensim

Summary:
I am trying to run the python file which contains face_recognition. But, it is giving me ModuleNotFoundError: No module named 'face_recognition'.
I have tried the way to solve:
I looked to similar problem in StackOverflow. I got the solution to install cmake,then dlib and then face_recognition.
pip install cmake has installed the cmake module successfully.
But when I am installing dlib using pip install dlib even I tried with pip3 install dlib,still it is gving me error. The error is shown as :
enter image description here
4)When wrote pip install dlib. It is giving me

You must use Visual Studio to build a python extension on windows. If you
are getting this error it means you have not installed Visual C++. Note
that there are many flavors of Visual Studio, like Visual Studio for C#
development. You need to install Visual Studio for C++.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!*
while i am using visual studio code only for development. I have already installed c++ in vs code(gcc compiler).
It is important to be solved, because:
1)Without this face_recognition module is not workin and I am not able to open the project as working file.
Feel free to ask any doubt needed to the problem. Any help will be respected.
you can try this blog to see if it works, hope this helps:

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-

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).
Windows 10 64bit
I installed traitsui successfully by pip in python3.52
Qt4 must be installed to display GUI on windows, But the highest version of python Qt4 support is python3.4
So, I install python3.4, when I try to install traits by pip
I got error message:
error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat)
I search the error message, get some results, But none of them solve the problem, So I install mingw
use pip to install traits again, get another error
collect2.exe: error: ld returned 1 exit status
error: command 'D:\\Program Files\\mingw-w64\\x86_64-5.3.0-win32-seh-rt_v4-rev0\\mingw64\\bin\\gcc.exe' failed with exit status 1
Is there a way to install traits on windows in python 3.4?
You can circumvent the problem of the error with Visual Studio C++ by installing a precompiled version of the package in form of a wheel. You can find wheel packages for most of the common modules here.
Download the file traits-4.6.0.dev0-cp34-cp34m-win32.whl (cp34 indicates Python 3.4, win32 that your Python is 32bit) and install it using the command line:
pip install C:\whereveryourfileis\traits-4.6.0.dev0-cp34-cp34m-win32.whl
Make sure that pip is linked to your Python 3.4 pip. If you are unsure, you can run the pip.exe directly by changing your directory in the command line (cd C:\Python34\Scripts) and running
pip.exe install C:\whereveryourfileis\traits-4.6.0.dev0-cp34-cp34m-win32.whl
Edit: Did you consider using Qt5?
