ImportError: cannot import name compat

I just installed 0.11rc2 and am getting an ImportError when trying to
save wiki pages. Here's the full stack:

I am getting the same error with Trac 0.11 final. I'm using the
official .tar.gz release on Ubuntu.

Well, I've resolved it by copying compat.py to compat2.py and
switching all the references to it in chrome.py. Bizarre.
Synchronization issue? Namespace issue? Not sure.

I too am getting this error with the release version of Trac 0.11 (see
below). However, it only happens sometimes. When I reload the page the
error disappears. I had been running Trac 0.11rc1 up until the upgrade
without any problems.

I tried going to python and importing compat, but that failed. I also
tried doing a search for compat using find, but still came up with
nothing. I'm using Leopard Server with Trac installed from
easy_install and everything else installed using macports.

This seems to have solved the issues for me (I think)...

sudo trac-admin /opt/local/var/trac/project/ deploy /opt/local/share/
trac/

I had manually copied the htdoc directory initially but forgot to copy
over the cgi-bin directory.

Never mind, I'm still getting errors.

[Jashugan]

I tried this, but it didn't help.

$ find . -name compat*
./trac/tests/functional/compat.py
./trac/tests/functional/compat.pyc
./trac/util/compat.py
./trac/util/compat.pyc

$ cd trac/tests/functional
$ sudo mv compat.py testcompat.py
$ sudo rm compat.pyc

I just tried this, but it seems to be working for now.

I had the same problem (Ubuntu trac 0,11)

The above trick worked for me as well. thanks

(To switch all references in chrome.py, do a global replace of
"compat." by "compat2.")

I had this same issue on OSX Leopard desktop (not server) when upgrading a 10.4 Trac to 0.11 Final and running apache 2.2.8 & mod_wsgi 2.0.

The solution below worked for me.

I had this exact problem on FreeBSD 6.3 after upgrading various
packages from ports. The solution below worked on my system, as
well. Doesn't make much sense, but I thank you all for this thread
and finding a workaround until newer builds fix the issue.
