Windows installation issue

[nsriram13]

Trying to use pip install wmd in Windows 10. I am using MSVC to compile from source. I have reproduced the log below. Can you please help troubleshoot?

I am afraid python 2.7 and older are not supported, only 3.4+. Besides, looks like an outdated pip... What's its version?

[nsriram13]

Output of pip --version
pip 9.0.1 from c:\program files\anaconda3\lib\site-packages (python 3.5)

I have defaulted my PYTHONPATH to Python 3.

[vmarkovtsev]

I cannot reproduce it on a test win10 machine... Looks like the compilation went terribly wrong. What's your c++ compiler version?

[vmarkovtsev]

Probably it has smth to do with anaconda environment, it is not supported (and never will be, officially).

[nsriram13]

Hmm... I am using Visual Studio 2015. So I think it is Visual C++ 14.0 compiler. I will try my hand at building it using MinGW using the cmake approach you have outlined in the docs. Fingers crossed it'll work - if not I will default to a non conda version. Thanks!

[xiaojieliu7]

have you sloved this problem?

[vmarkovtsev]

No, unfortunately not. I am not using Windows. PRs and fixes welcome.

[m-piccolino]

@nsriram13 did you manage to get this working somehow?

[nsriram13]

@m-piccolino - Sorry - do not have any updates on this. I switched to using Linux after running into similar build issues for other packages.

Did someone solve the problem for Windows?
