Hi,

I'm new to mod_wsgi and had a simple question -- I couldn't find this
in the group archives or elsewhere.

I'm getting a simple ImportError -- no module named CherryPy -- when I
try to use the first method cited in this [http://code.google.com/p/
modwsgi/wiki/IntegrationWithTurboGears#whb] article.

{{{

}}}

My sys.path includes cherrypy:

{{{

['/usr/lib/python25.zip', '/usr/lib/python2.5', '/usr/lib/python2.5/
plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-

tg/', '/usr/lib/python2.5/site-packages/CherryPy-2.2.1-py2.5.egg/
cherrypy/']

}}}

And I'm able to import cherrypy normally from the command line:

{{{

$ python
>>> import cherrypy
>>>

}}}

Any clues on where I might be going wrong?

It should only use:

/usr/lib/python2.5/site-packages/CherryPy-2.2.1-py2.5.egg

in the path. It shouldn't include 'cherrypy' at the end.

Are you adding that into sys.path yourself. By rights you shouldn't
need to if setuptools stuff is all installed correctly as it should
activate when Python startups and automatically add the path itself.

Thanks, and apologies that I can't put the code snippets in WikiFormatting.

This path /usr/lib/python2.5/site-packages/CherryPy-2.2.1-py2.5.egg is

'/usr/local/lib/python2.5/site-packages',
'/usr/lib/python2.5/site-packages',
'/var/lib/python-support/python2.5']

So I added a simple debugging statement to my tg.wsgi code:

sys.stdout = sys.stderr
print sys.path

When I examine the error logs, I get a very different starting sys.path:

Apache error.log:

[Wed Sep 26 09:26:00 2007] [error] ['/usr/lib/python25.zip',
'/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2',
'/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload',
'/usr/local/lib/python2.5/site-packages',
'/usr/lib/python2.5/site-packages']

I tried manually appending the CherryPy path, in tg.wgsi as:

sys.path.append('/usr/lib/python2.5/site-packages/CherryPy-2.2.1-py2.5.egg/')

And this shows up faithfully in the error.log under sys.path

[Wed Sep 26 09:26:00 2007] [error] ['/usr/lib/python25.zip',
'/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2',
'/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload',
'/usr/local/lib/python2.5/site-packages',
'/usr/lib/python2.5/site-packages','/usr/lib/python2.5/site-packages/CherryPy-2.2.1-py2.5.egg/']

But I still hit the ImportError: no module named cherrypy.

If it helps, I've also pasted my tg.wsgi code below:

-------------

import sys
# Taken from http://code.google.com/p/modwsgi/wiki/IntegrationWithTurboGears

# Need to set this path automatically when we move out from the
repository into the build path
sys.path.append('/mnt/local/deploy/tg')
sys.path.append('/usr/lib/python2.5/site-packages/CherryPy-2.2.1-py2.5.egg/')

sys.stdout = sys.stderr
print "------"
print sys.path
import os
os.environ['PYTHON_EGG_CACHE'] = '/mnt/local/deploy/tg/eggs/'

import re
import atexit
import cherrypy
import cherrypy._cpwsgi
import turbogears

turbogears.update_config(configfile="dev.cfg", modulename="tg.config")
turbogears.config.update({'global': {'server.environment': 'production'}})
turbogears.config.update({'global': {'autoreload.on': False}})
turbogears.config.update({'global': {'server.log_to_screen': False}})

if cherrypy.server.state == 0:
atexit.register(cherrypy.server.stop)
cherrypy.server.start(init_only=True, server_class=None)

import tg.controllers

cherrypy.root = tg.controllers.Root()

application = cherrypy._cpwsgi.wsgiApp

What is in:

/usr/lib/python2.5/site-packages/CherryPy-2.2.1-py2.5.egg/

Is it an expanded set of directories or is this a packed egg, ie., single file?

What is in:

/mnt/local/deploy/tg/eggs/

ie., what eggs have been unpacked in there.

Does the user Apache runs as have write permission to the egg cache?

It is an expanded set of directories:

$ ls -al /usr/lib/python2.5/site-packages/CherryPy-2.2.1-py2.5.egg/
total 16
drwxrw-r-x 4 root www-data 4096 Sep 21 22:50 .
drwxrw-r-x 32 root www-data 4096 Sep 26 11:41 ..
drwxrw-r-x 2 root www-data 4096 Sep 21 22:50 EGG-INFO
drwxrw-r-x 6 root www-data 4096 Sep 21 22:50 cherrypy

The Apache user runs as:

User www-data
Group www-data

> What is in:

Nothing is in this directory -- I thought this was where eggs would be
unpacked at runtime if so needed:

$ ls -al /mnt/local/deploy/tg/eggs

total 8
drwxr-xr-x 2 root www-data 4096 Sep 26 00:58 .
drwxr-xr-x 6 root www-data 4096 Sep 26 00:58 ..

I originally ran into the permissions error -- but after I chown'd -R
root.www-data, that error disappeared and I was left only with the
ImportError.

Thanks,

T.U.

I cant see how it would matter as still o+x, but you don't have g+x on
the directory permissions.

Run:

cd /usr/lib/python2.5/site-packages/CherryPy-2.2.1-py2.5.egg
find . -type d -print -exec chmod 0775 {} \;

This will ensure that g+x is on all directories under that location.

Also ensure that the .py files in the directory hierarchy are sensible as well.

That shouldn't have been required on the Python site-packages
directory unless the directory permissions were screwed up in the
first place such that they weren't readable to others. In general you
shouldn't be changing ownership of stuff in Python site-packages at
all.

Just wanted to follow-up here, any tips on this?

I'm still getting the same error [from my apache error logs]:

[Wed Oct 17 01:20:18 2007] [error] [client xx.yy.zz.aa] mod_wsgi

The permissions on the directory /mnt/local/deploy/tg/eggs:

drwxr-xr-x 2 root www-data 4096 Oct 17 00:52 eggs

The permissions on the directory /mnt/local/deploy/tg/apache:

drwxr-xr-x 2 root www-data 4096 Oct 17 01:03 apache

And on the cherryPy directory:

drwxrw-r-x 4 root www-data 4096 Sep 21 22:50 CherryPy-2.2.1-py2.5.egg

Thanks again - seems pretty simple, but I can't seem to track it down,
so I appreciate your help!

I apologize - I didn't seen Graham's email dated 9/27/2007 -- it
appears online in the googlegroup, but I didn't see the reply in my
inbox.

However, I implemented this suggestion in the CherryPy dir:

$ find . -type d -print -exec chmod 0775 {} \;
$ ls -al
drwxrwxr-x 4 root www-data 4096 Sep 21 22:50 .
drwxrw-r-x 32 root www-data 4096 Sep 28 17:49 ..
drwxrwxr-x 2 root www-data 4096 Sep 21 22:50 EGG-INFO
drwxrwxr-x 6 root www-data 4096 Sep 21 22:50 cherrypy

but I'm still getting the same permissions error:

Thanks - and apologies for missing your earlier post.

Go:

cd /usr/lib/python2.5/site-packages
ls -lasg

Post the output.

Also do:

cat setuptools.pth

and post the output.

Your site-packages directory must be screwed up in some way, with
permissions wrong such that Apache user can read something important.

The only other possibility is that you have SELinux extensions enabled
and it is stuffing things up.

You have really mucked up the permissions on your Python installation,
but possibly should still be okay. You might though want to consider
uninstalling your Python installation, manually removing any residuals
in site-packages, delete Python lib directory and then reinstall
everything. This time don't go manually change permissions and
ownership on things if you are unsure about what you are doing.

BTW, are you setting PYTHON_EGG_CACHE environment variable in WSGI
script file as described in documentation for mod_wsgi? This would be
needed as some of your eggs aren't unpacked. The directory you denote
by the variable must be writable to the Apache user.
