Distribute (which was a well-maintained fork of setuptools) is now renamed back to setuptools. So setuptools 0.7 (and now 0.8) is out. And distribute is deprecated.
But since distribute had to pretend it was really setuptools, all sorts of hacks needed to be used. And now all those hacks have to be worked around again. => problems.
I now run into buildout problems. Running bootstrap can fail:
$ python bootstrap.py
Traceback (most recent call last):
File "/home/vagrant/tools/bin/python", line 66, in <module>
exec(compile(__file__f.read(), __file__, "exec"))

raise VersionConflict(dist,req) # XXX put more info here
pkg_resources.VersionConflict: (setuptools 0.6c11
(/usr/lib/python2.7/dist-packages), Requirement.parse('setuptools>=0.7'))
Solution is apparently to download a fresh bootstrap: http://downloads.buildout.org/2/bootstrap.py
For me, that didn’t help as a global setuptools/distribute installation was in the way.
Apparently I really need to update my local setuptools installation. Hey, there’s a new new temporary distribute that installs the actual 0.8 setuptools for you:
$ sudo pip install -U distribute

Oh what?? That was on OSX. Let’s try again:
...
ImportError: Entry point ('console_scripts', 'easy_install') not found
Oh hell, my entire installation got mutilated.
I saw that too on one of my ubuntu boxes:
$ sudo easy_install -U distribute
Traceback (most recent call last):
File "/usr/local/bin/easy_install", line 9, in <module>
load_entry_point('distribute', 'console_scripts', 'easy_install')()

raise ImportError("Entry point %r not found" % ((group,name),))
ImportError: Entry point ('console_scripts', 'easy_install') not found
Normally I’d take that as a message that a previously-patched-and-thus-empty setuptools installation is now used. But…
What worked:
$ wget https://bitbucket.org/pypa/setuptools/raw/0.8/ez_setup.py
$ sudo /usr/bin/python ez_setup.py
This gives you a nice fresh globally installed setuptools 0.8.
Somehow some of my buildouts had a development egg link to a
setuptools or distribute version. For that I had to remove the
contents of the develop-eggs/ directory in my buildout.
I use a recipe (syseggrecipe) that makes it easier to use globally installed packages. Especially handy for numpy/scipy and geographical libraries.
It works by adding development egg links to those packages it finds. And, of course, one of those directories with one of those packages also contained an older version of setuptools:
$ python bootstrap.py
Setting socket time out to 1 seconds.
$ bin/buildout
Setting socket time out to 1 seconds.
While:
Installing.
Checking for upgrades.
Error: There is a version conflict.
We already have: setuptools 0.6c11
but zc.buildout 2.2.0 requires 'setuptools>=0.7
The solution here:
$ sudo rm -rf /usr/lib/python2.7/dist-packages/setuptools*
Zap setuptools and distribute in any global locations that can interfere.
Install setuptools 0.8 with the ez_setup method that I also showed as ‘solution 3’ above.
Use the latest buildout bootstrap (‘solution 1’).
