pip crashes after successful update: setuptools-12.0.5-py2.7.egg' not found about molecular-design-toolkit HOT 3 CLOSED

Following up with more info as requested by @avirshup:

$ pip --version
pip 8.1.2 from /usr/local/lib/python2.7/site-packages (python 2.7)

Running the notebook (python -m moldesign intro) had no issues and I was able to do all steps from Example 1 without any problems.

Thanks for the report, Joseph!

For posterity: This appears to be pypa/pip#2545. The problem, as best as I can understand, is that setuptools was NOT installed with pip (it probably came with homebrew instead). However, pip -U moldesign upgraded it anyway (here, from v 12.X -> v 25.X) - this is the expected behavior.

The problem is that, when trying to clean up outdated metadata, pip tries to remove the old .egg-info file, which was never created. So pip crashes, leaving some extra metadata lying around, which probably doesn't affect anything. (?)

@joseph-schaeffer, could you try running pip install -U moldesign again to see if the message reappears? Hopefully, this is a one-time cosmetic error for when you update setuptools.

@avirshup: Ran it again with no message reappearing. I agree, looks like the referenced issue with pip rather than anything directly with mdt.
