I'm trying to pip install aubio package to Python on 64-bit windows 10.
The problem seems to be that I can't build the wheel.
I get a dialogue box saying "the program can't start because mspdb140.dll is missing from your computer. Try reinstalling the program to fix this problem."
Not exactly sure which program it is even referring to...
I've downloaded Visual C++ 14.0 and the aubio zip files which I think are what it's telling me I need: I've tried pip installing and have downloaded Visual C++ 14.0 and the aubio zip files which is what I think I need.
Here's the final error code I get:
Command "C:\Users\danci\Anaconda3\python.exe -u -c "import setuptools,
tokenize;__file__='C:\\Users\\danci\\AppData\\Local\\Temp\\pip-build-
d5772nkl\\aubio\\setup.py';f=getattr(tokenize, 'open', open)

__file__, 'exec'))" install --record C:\Users\danci\AppData\Local\Temp\pip-

compile" failed with error code 1 in C:\Users\danci\AppData\Local\Temp\pip-
build-d5772nkl\aubio\
Also, about halfway through installation I get this:

d5772nkl\aubio\python\lib\gen_external.py", line 108, in get_c_declarations

Failed building wheel for aubio
thanks.
It seems something is missing to your setup. To compile a python extension on windows, you will need the compiler that was used to build your python binary.
See this page about windows compiler to find out the correct version to use: https://wiki.python.org/moin/WindowsCompilers

I have already installed the build tools following the link description but it still doesn't work. If someone has solved it, please tell me how to fixed it.
Download twisted from this link.
Downloading Twisted‑18.4.0‑cp36‑cp36m‑win32.whl worked for me because I'm using Python 3.6. Download the version according to the python that you use.
After you download Twisted from the given link, open up a cmd where the file is located and run pip install Twisted‑18.4.0‑cp36‑cp36m‑win32.whl. pip will install Twisted from this file.
If you're doing it in a virtualenv, activate the virtualenv and install Twisted after that in the same process.
After that, you'll be able to install channels or whatever.
if you followed the instructions as mention by #rahim.nagori and encounter the problem as mention by #DiptangsuGoswami. just download the 32bit version of twisted or 64bit (if what you used previously was 32bit). it worked for me!
I use this command for installing MySQL client:
pip install mysqlclient
And then I see this problem:

Actually I went down this path. While I suppose you can find all the libraries and components you need to get the client to compile, it is telling you it can't find a compiled copy of the client and is trying to compile it to install it.
Follow the instructions here: https://pypi.org/project/mysqlclient/ (it has notes about windows doing what you are describing) or download the wheel file (from downloads link on the page) and type
pip install mysqlclient.whl
and it will install without demanding C++ in order to use mysql with python.
I am new to the Wagtail cms and am taking over a friend's project for his site.
I have downloaded his repo and am trying to get it to run locally. I have followed the steps on the wagtail documentation http://docs.wagtail.io/en/v1.12.1/getting_started/index.html
but in the site's requirements.txt file, there are some dependencies that just are not installing and giving errors:
here is the output of when trying to install the requirements:

Any help would be greatly appreciated - I am using Python 2.7 and have tried reinstalling psycopg and have installed postresql
Your windows linker is throwing out errors as you don't have c++ libraries for an extension to be built properly.
I would suggest to you to rather install it through wheel file
by running
pip install some-package.whl
I'm not sure if this is the answer, but the version of psycopg2 that you're using had a bug that prevented installation using pip, due to some bug in pip. Try version 2.5.3 and see if that fixes it.
I am using Python for making a script to work with some chemical structures in my PhD. I want to install openbabel libraries for python. I tried my best but I could not install it. It always gives error:
Error: SWIG failed. Is Open Babel installed?
Here is the Python Path on my PC: C:\Users\malih\AppData\Local\Programs\Python\Python36-32. Openbabel is installed at the following path C:\Program Files (x86)\OpenBabel-2.3.1.

You may need to manually specify the location of Open Babel include and library directories. For example:

python setup.py install

Please help me on this as my work is based on this and I am stuck at this point. Thanks in advance for your time.
pip install is notoriously non-windows friendly. Either go to openbabel website and download + install windows binary, then download + install python binding, or use the unoffical official openbabel python windows build, then cd into the downloaded directory, and perform pip install OPENBABEL_FILE_WINDOWS.whl
I recently had do some quite a bit of work on 2D mol file -> 3D mol file translation using openbabel. Let me know how it works out for you.

edit: I should also add, python3.x is breakingly different to python2.x. So if anything breaks, try it with python2.x
This is somewhat old, but the problems still persist so i'll answer nonetheless.
The precompiled Windows binary (most likely) doesn't come with SWIG built-in, which in turn doesn't offer language bindings and gives you the error when installing from pip.
A workaround to this is to install a wheel from the unofficial Windows binaries website just like pandamakes answered.
However, the wheels already comes bundled with a precompiled obabel, so you really don't need to install the windows binaries version (the one that comes with the setup and all), but you have to know that if you're willing to ship a python script that uses this library, know that it will interfere with systems that do have BABEL_DIR in the environment variables, to fix this you have to include the whole openbabel directory from YourPythonDirectory/lib/site-packages/. in your script's folder.
Another important note is that some babel builds from the unofficial binaries website have a bug where they do not detect all file formats, especially the most common ones like sdf/pdb/mol2 or even smiles. The only versions i have confirmed working somewhat flawlessly so far are the openbabel‑3.1.1‑cp36‑cp36m‑win32.whl and openbabel‑3.1.1‑cp38‑cp38‑win32.whl.
I am trying to install Scrapy.
I am getting this error. I know there are many questions exists on SO but none of a solution has worked for me.

I have these things installed in my computer
I have System Variable name:value is VS100COMNTOOLS:VS140COMNTOOLS
I also have OpenSSL installed in OpenSSL-Win64 and added to Windows PATH
I also have Microsoft Visual C++ Compiler for Python 2.7 installed.
What should I do? I have tried all solutions provided on SO but none worked.
I got this working.
Usually these require very particular versions of the Visual studios C++ compiler. In this case, following the steps listed on this page for the "Microsoft Visual C++ 10.0 standalone: Windows SDK 7.1" worked for getting twisted running (which is the package that's screwing up in this case)
If that doesn't work, you can find unofficial wheels here (learn more on wheels in general here)
Download the correct wheel (in this case, twisted) and follow these instructions to install it.
Hope this helps.
