There's an error bubbling up from QCEngine:

I can't find documentation around any version restrictions around non-ancient versions (surely we're not installing 1.2) and the failure coming from parsing STDOUT implies that it's just not installed correctly. I raised #214 which might help this.

There's an error bubbling up from QCEngine:

This normally means psi4 was not installed correctly. The current pins in the env were what I could get to work consistently and were taken from qcengine I am not sure why this would suddenly break though.

[mattwthompson]

Looks like the installation step went fine and it's working on the tests, which have gone for a half hour now and will probably hang, so I'm cancelling them now.

Merging this now as per #218 (comment)
