Fix sphinx python version #228

Closed matt-chan closed 7 years ago

matt-chan commented 7 years ago

Somehow the new version of sphinx-build defaults to python 3. Maybe pip changed their behaviour. This forces it to use python 2. Fixes #227

This will not work on all platforms, e.g. when I install sphinx with pip, there is no sphinx-build-2. I guess the name sphinx-build-2 is specific for Fedora packages.
