Ironically, the tests are failing because this isn't merged and so it can't test itself :)

pypa/setuptools#1042

[asottile]

I don't think this would actually fix it either because it's too late (setuptools is imported in setup.py)

I do think we should consider setting VIRTUALENV_NO_DOWNLOAD as a framework (I wish they hadn't made that change to virtualenv in the first place)

[mikeage]

It seemed to fix it in my local tests, but VIRTUALENV_NO_DOWNLOAD might definitely be cleaner

[chriskuehl]

+1 for VIRTUALENV_NO_DOWNLOAD, we saw a lot of failures internally installing new pre-commit hooks during the time the bad setuptools release was out.

In any case, a new release of setuptools was made (36.0.1), so the pinning shouldn't be necessary anymore.

[asottile]

Here's my PR to address this in the framework: pre-commit/pre-commit#542

going to close this given we'll try and blanket fix it there and setuptools 36.0.1 fixed the other problem
