Unable to build python packages

[spl0i7]

• Pip version: 9.0.1
• Python version:3.6.0
• Operating System:Windows 10 (x64)

Description:

I am unable to install most of python packages because it just won't build. It says ValueError: Unknown MS Compiler version 1900

What I've run:

> pip install numpy

[pfmoore]

As you're building from source you need the correct compiler toolchain and libraries present. MSVC 1900 is Visual Studio 2015, which should be right for Python 3.6, but the last section of the trace refers to distutils\cygwinccompiler.py. I don't know why it would be using this. Are you using cygwin? You seem to be picking up a non-cygwin Python, which is good. Do you have a distutils or pip config file that's forcing the cygwin compiler? Or could numpy be doing something to require gcc?

But I already installed microsoft build tools. How can I fix this?

This is a numpy build issue - you should probably ask on their support list. Possibly the numpy extensions to distutils (numpy.distutils._msvccompiler) don't support MS Visual C++ Build Tools, but only the full Visual Studio? I'm afraid I don't know the answer to that.

Alternatively or additionally, numpy have released stable binary wheels for python 3.6 on OS X and linux, but not Windows, you could ask if they could build them.

They already have Windows python 3.6 binary wheels for their 1.12.rc2 release, but pip won't grab release candidates by default.

If pip can find a compatible binary wheel for something it installs very simply, without the need for getting compiler toolchains right.

Yup, this is a numpy issue, not a pip one.
