Answer 1

I met this problem when I was trying to build ujson package with python 2.7 (compiled with VS 2015).

• vcvarsall.bat: try to copy vsvars32.bat (from the same directory - "c:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools") to vcvarsall.bat. It's all you need for build
• another problem is detecting VS version in function get_build_version() (distutils/msvc9compiler.py). You need to change this function to return right version of VS.

There is this line:

majorVersion = int(s[:-2]) - 6

it sets majorVersion to 13, but the correct version for VS 2015 is 14. So you need add two line, for example:

if majorVersion == 13:
    majorVersion = 14
