Windows installation issue

nsriram13 commented 7 years ago

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 Besides, looks like an outdated pip...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 commented 7 years ago

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.

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

vmarkovtsev commented 7 years ago

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

nsriram13 commented 7 years ago

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!
