在安装python 3.5的numpy时遇到问题

Question

I have been trying for over 2 hours to install numpy module for python 3.5

for some reason i keep getting this error at the end

building library "npymath" sources
No module named 'numpy.distutils._msvccompiler' in numpy.distutils; trying from distutils
error: Unable to find vcvarsall.bat

I read a lot about this problem from other people. but can't seem to figure out how to fix it for me.

i Have:

Microsoft Visual c++ 2013 Redistributable

Microsoft Visual c++ 2012 Redistributable

Microsoft Visual c++ 2010 Redistributable

any help will be good!

Thanks

ps this is the full output

Answer 1

The problem is related with VisualStudio (default) installation.

While installing VS 2015 Community Version, you normally choose the default express installation, which DOES NOT INCLUDE LANGUAGE SUPPORT UTILITIES, including Python.

So you should include Programming Languages option in the installation menu at the very beginning. Otherwise the VC2015 is installed but the Python support is not.

Answer 2

Hmm the Python support in MSVC is not needed to build NumPy - it is just an interface to let you edit Python files using MSVC if you love Visual Studio. NumPy actually uses just the C++ compiler. vcvarsall.bat just sets the environment variables for MSVC builds for you as a convenience function, which NumPy couldn't find while you were trying to build. I take it you were trying to make a custom installation? OpenBlas or something? Just download a binary online you can find ATLAS builds and MKL http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy , then you save yourself the hassle of building from source (and it is a MAJOR hassle in my opinion)... Oh BTW you can't install any packages for Python 3.5 using Visual Studio 2013, it is built using Microsoft Visual Studio 2015 so just download the 2015 community version if going that route https://www.visualstudio.com/en-us/products/visual-studio-community-vs.aspx You'll also need it anytime you compile a package with python setup.py install
