Fresh install: name 'long' is not defined (dependency issue)

[pgkirsch]

Fresh installation on a new laptop. Cloned gpkit repo and ran tests (using python 3.9.7), returned a NameError. Looks like the problem is with the ad package but creating a ticket here for tracking.

Hmm looks like I'm only able to install an old version of ad for some reason. Definitely not a gpkit issue so I'll close.

[pgkirsch]

Created an issue in the ad repo.

[whoburg]

Great catch... hmm, if ad is a dependency, shouldn't we lock the version to something that works, until this is fixed on their side? We could include a comment in setup.py reminding us to unlock eventually.

[pgkirsch]

Yes although I believe what needs to be fixed is the version of setuptools (<58) and I don't know if that's too meta to do in setup.py...

[bqpd]

hmm, if we specify a minimum ad version it'll at least not install it when that happens; 1.3.2 seems to work on py.3.5.2, so I'll specify ad >= 1.3.2
