See the posts from Felix Schwarz here a few days ago. It looks like he ran into and debugged the same issue. I haven't had a chance to wade into it. (I can't say I'm looking forward to it.) I'll try to get up to speed on this this weekend. Jim On Thu, Apr 12, 2012 at 6:16 AM, Wichert Akkerman wrote:

So at this point I can import the repoze namespace packages, which is defined by both repoze.sphinx.autointerface and repoze.formapi. Now I try to import repoze.sphinx.autointerface:

(Pdb) import repoze.sphinx.autointerface *** ImportError: No module named autointerface

That is unexpected since we saw the repoze.sphinx.autointerface egg was found earlier. So lets look at repoze.sphinx:

(Pdb) repoze.sphinx

I did not see that coming at all: how can a system sphinx package that is not inside the repoze namespace suddenly appear there? This is especially odd since buildout hooked me up with a sphinx package in the buildout itself:

(Pdb) import sphinx

I am not sure who is responsible for this behaviour or how to debug this. Does anyone have any useful hints?

Wichert.

Interesting. As a data point: I use zc.buildout 1.5.2 on Ubuntu 11.10. I haven't encountered any namespace issues yet.

Here is a pdb session to demonstrate:

(Pdb) import repoze (Pdb) repoze (Pdb) repoze.__path__ ['/home/wichert/lib/buildout/eggs/repoze.sphinx.autointerface-0.6.2-py2.7.egg/repoze', '/home/wichert/lib/buildout/eggs/repoze.formapi-0.4.2-py2.7.egg/repoze']

(Pdb) import repoze.sphinx.autointerface *** ImportError: No module named autointerface

(Pdb) repoze.sphinx

Do you have a small sample buildout.cfg so that I could try to reproduce this? This one worked for me: $ cat buildout.cfg [buildout] parts = wtf [wtf] recipe = z3c.recipe.scripts # recipe = zc.recipe.egg also worked fine eggs = Sphinx repoze.formapi repoze.sphinx.autointerface interpreter = python $ python bootstrap.py $ bin/python Python 2.7.2+ (default, Oct 4 2011, 20:03:08) >>> import repoze >>> repoze.__path__ ['/home/mg/.buildout/eggs/repoze.formapi-0.5.0-py2.7.egg/repoze', '/home/mg/.buildout/eggs/repoze.sphinx.autointerface-0.6.2-py2.7.egg/repoze'] >>> import repoze.sphinx.autointerface >>> repoze.sphinx even though I also have sphinx installed into my dist-packages (/usr/lib/pymodules/python2.7/sphinx/__init__.pyc exists).

I did not see that coming at all: how can a system sphinx package that is not inside the repoze namespace suddenly appear there? This is especially odd since buildout hooked me up with a sphinx package in the buildout itself:

(Pdb) import sphinx

Not really. I'm afraid when I encounter buildout issues, I'm in the "aaargh no time for yak shaving NOW" mode, so I tend to intuitively twiddle some knobs like 'include-site-packages = false' for 10-15 minutes until it starts working. Marius Gedminas -- Hanlon's Razor: Never attribute to malice that which is adequately explained by stupidity.

Let me try to answer some questions that came up: - the buildout I used to reproduce this is this one: https://github.com/euphorie/Euphorie - this was using buildout 1.5.2 On 2012-4-12 12:16, Wichert Akkerman wrote:
