On Windows, python 2.7 conflicts with flang?

[roryyorke]

I'm trying to setup CI builds on Appveyor, see here. The Python 3 (3.5, 3.6, and 3.7) builds seem to be fine.

It looks like Python 2.7 and conda-forge's flang aren't compatible. Is that right?

I don't know if that's a problem, but perhaps we should note it somewhere.

The error is:

conda.exceptions.UnsatisfiableError: The following specifications were found to be in conflict:
  - flang
  - python=2.7

Yes.
I don't think it is very productive to try to fix this issue with python 2.7, deprecation is around the corner.
People insisting on using python 2.7, windows and slycot in combination may get the slycot from cgohlke's page

Incompatibility noted in #52.
