Mosek install error

Running with Anaconda2, Python 3.7, Mosek 8 (although I also saw this issue when running with Mosek 9) on someone else’s machine. Got this error:

When I run python python -c "from gpkit.build import build; build()" it looks good so I’m surprised that this is not working

I get this result

v0.9.9 is the last one to support Python2.7 and the mosek C-bindings interface for mosek 7/8

the current dev branch does not support either of those 😕

both v0.9.9 and the current dev branch support Python3, mosek 7/8 via the mosek_cli interface and mosek 9 via the mosek_conif interface

[mjburton11]

ok so so I’m still confused here. mosek doesn’t work with python 3 but mosek_cli does? and does gpkit still support python 2.7?

What are the optimum settings here: python 2.7 or 3? gpkit dev? mosek 9 or 8?
