Setuptools 0.8 and Distribute 0.7.3 (legacy wrapper) now released

[Jason R. Coombs]

The PyPA is excited to announce the public release of Setuptools 0.8. This release of setuptools provides no additional functionality over Setuptools 0.7.x except that it no longer requires 2to3 to build/install on Python 3. What this means for packaging is that tools like pip and virtualenv can now invoke setuptools directly on all supported Python versions (currently 2.4+). This build enables more natural upgrades and helps address many of the bugs that the 2to3 conversion process triggered.

 

Additionally, Distribute 0.7.3 has also been released to PyPI. Distribute 0.7 was designed to ease the upgrade process from Distribute 0.6.x to Setuptools 0.7. This new version, 0.7.3, is a re-release of the legacy wrapper 0.7, but additionally bundles the Setuptools 0.8 code for the purposes of bootstrapping the upgrade. This version specifically eases upgrades on systems running older systems. Now, one can readily upgrade any environment with Distribute 0.6 by simply upgrading (using pip or easy_install) to Distribute 0.7.3, which will replace the ‘distribute’ package with an empty shell leaving setuptools >= 0.7 (probably 0.8) installed.

 

Enjoy, and please report any issues with either of these packages at the Setuptools project page (https://bitbucket.org/pypa/setuptools).

I tried this on OSX and ran into a problem:

$ sudo pip install -U distribute

So it downloaded 0.7.3 just fine, but barfed on a non-zipfile distribute
0.6.28. The directory didn't exist afterwards, so I assume the upgrade
process somehow removed it (or it got confused because it was or wasn't
a zipfile).

Afterwards nothing pip-related worked as it missed setuptools.
The `/usr/bin/easy_install setuptools` also didn't work.

So I had to set it up anew, which worked:

$ wget https://bitbucket.org/pypa/setuptools/raw/0.8/ez_setup.py
$ sudo /usr/bin/python ez_setup.py
