git review 1.24 fails on OS X 10.9.2 with pkg_resources.DistributionNotFound: git-review

[Artem Borzilov]

After i updated git-review it fails with the following traceback:

air-aleksandra:rally uppi$ git review
Traceback (most recent call last):

pkg_resources.DistributionNotFound: git-review

After installing git-review==1.23 it works again.

This is a problem in pkg_resources, and can be fixed by: sudo pip install --upgrade setuptools.
It works fine with setuptools-5.3.

[Jeremy Stanley (fungi)]

It looks like this is fixed by running the new setuptools 0.7 or later rather than the older distribute fork of setuptools (it can also be solved by running git-review from a relatively modern virtualenv). However, since there's no effective way to force a newer setuptools on install, the most we can hope to do is catch this exception and provide a slightly more helpful error message to the end user with relevant recommendations.
