问题
I have been trying to install matplotlib through install_requires and it has been failing with error: unexpected html page found...
When I just try to install it regularly through pip it seems to work fine.
Does anyone know how to fix this kind of issue with install_requires. I would like setup.py to handle these issues. I had a similar problem with numpy failing with Python.h problems, but then a regular pip install fixed that as well.
