trac-admin fails with DistributionNotFound error

[koch@…]

After installing trac 0.11.1 using ​http://ftp.edgewall.com/pub/trac/Trac-0.11.1.win32.exe over an existing (working) 0.11 Version i run in the following trouble.

C:\Python24\Scripts>trac-admin c:\Projects\test.trac.db
Traceback (most recent call last):
  File "C:\Python24\Scripts\trac-admin-script.py", line 5, in ?
    from pkg_resources import load_entry_point
  File "C:\Python24\lib\site-packages\setuptools-0.6c7-py2.4.egg\pkg_resources.p
y", line 2564, in ?
    for dist in working_set.resolve(
  File "C:\Python24\lib\site-packages\setuptools-0.6c7-py2.4.egg\pkg_resources.p
y", line 524, in resolve
    raise DistributionNotFound(req)  # XXX put more info here
pkg_resources.DistributionNotFound: Trac==0.11.1

Did i miss something?

You probably still have the Trac 0.11 egg in your site-packages directory.

That's the clue I needed.

MayBe something for the install notes?

Remove existing Trac x.xx egg in your site-packages directory.

Added a comment about that in TracUpgrade.

I had this same problem and I resolved this by creating a .pth file in my system's site-packages directory containing the path to my custom trac site-packages directory:

I created: /usr/lib/python2.5/site-packages/trac.pth, which contains:

/opt/trac/lib/python2.5/site-packages

This is the path where I custom installed trac from source.

Hi.. I got the same error. I still don't know what to do. I 've installed Trac.0.12 in Debian. I could not make any environment and got this following error:

Traceback (most recent call last):
  File "/usr/local/bin/trac-admin", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 2675, in <module>
    parse_requirements(__requires__), Environment()
  File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 552, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: Trac==0.12

Anybody can help me? Thank you in advance guys…

On Windows, I do encounter similar problems, but only if I run the python as a USER. If it's under SYSTEM or Admin rights, it runs correctly.. But still don't know, how to solve it, I do not want to run Pyhton with SYSTEM rights.. Any ideas?

You need to give the permissions to USER to your python path. I was trying to run post commit scripts in SVN that do a changeset added operation. The post_commit.cmd is run as user NETWORK SERVICE so i added full control to that user to both trac_env dir and to the python dir and eureka!
