Visual C++ for python failed with exit status 2 when installing divisi2

Question

I am using Python 2.7 on Windows 8.1 46 bit.

I want to install divisi2

I have installed NumPy and SciPy which are the pre-requisites for divisi2 already. I have installed Visual C++ for python 9.0.

Whenever I issue the pip install divisi2 command I get the following error in the console.

Answer 1

Both the above methods work nicely.
This one is a bit easier though.
Install Visual C++ 2015 Build Tools from https://go.microsoft.com/fwlink/?LinkId=691126 with default selection.

Answer 2

Came across this issue when installing pycocotools on windows 10. Python 2.7 is incompatible or does not support Visual C++ 14 that is required to compile C99 code. This is the reason for the compiling errors (C2065,C4047 etc).

You need to,

1. Install Visual Studio 2015 build tools (this will install C++ 14 compiler).
2. Install a new newer version of Python (3.6 recommended)

Answer 3

I finally solved this problem after getting this hint from a colleague i.e. to use

https://github.com/develersrl/gccwinbinaries.

This will install the requisites and then you can install divisi2.
