Python pip install errors (feather-format)

I've been trying to install the Feather file format for Python (https://pypi.python.org/pypi/feather-format) for the last few days with no luck. I'm using Anaconda2 on Windows 10. I get the following errors when I try to pip install feather-format:

You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.


It all seems to have to do with c++. I've installed (and reinstalled) the Microsoft Visual C++ Compiler for Python (https://www.microsoft.com/en-us/download/details.aspx?id=44266). I also installed Visual Studio 2015.

I am able to install feather-format using

conda install feather-format


but I get the following errors when I include feather in a script:

It cant seem to compile (?) the file "ext.pyx" from the source directory. Any help would be appreciated and thanks very much.

Answer

I have faced the same problem when I was installing Feather Format for Python. You can try this code on your Command Line

conda install feather-format -c conda-forge 

The reason of the error might be the wrong compiler for C++, you can use conda-forge as a compiler. This has already integrated in Anaconda.
