Well, as the error messsage says, you will have to install ClearSilver to use Bitten for now, as I don't want to break compat with Trac 0.10 at this point.

I think Clear Silver? is installed :

# easy_install ClearSilver
Searching for ClearSilver
Best match: clearsilver 0.10.1
Processing clearsilver-0.10.1-py2.4-linux-i686.egg
clearsilver 0.10.1 is already the active version in easy-install.pth

Dear cmlenz!!! Clear Silver? installation is NOT source for this trouble! Please, DO NOT formal reply. Feature must be review and eliminated. Thanks, beforehand!

[cmlenz]

Well, for some reason Trac thinks that Clearsilver is not properly installed, because (a) it's not in the installation information table, and (b) you're getting that error.

So, please trydo the following: on the command line, enter:

  $ python -c "import neo_cgi; print dir(neo_cgi)"

and report back the output.

If that works, do you maybe have multiple versions of Python installed? Are you sure that the process running Trac is using the same Python used on your command-line?

[traydent@…]

Got this from the command line

# python -c "import neo_cgi; print dir(neo_cgi)"

I had exactly the same problem with trac 0.11, current svn bitten [547] and ​clearsilver 0.10.1. I resolved it by installing clearsilver 0.10.5 from source, similar to ​this person.

I had originally tried to easy_install clearsilver which could provide only 0.10.1. I think this would be a common mistake, so it might be worth indicating which versions are compatible in the bitten installation instructions, or even testing for the clearsilver version and giving a more specific error message. That said, I think this is a configuration issue, and not a bitten bug.

Thanks,

Iain Haslam.

Suggested patch for installation docs.

[osimons]

Using a recent Trac 0.11.x and current Bitten 0.6dev from trunk, there is no longer any ClearSilver/HDF code remaining. Everything should run fine without it installed. Please reopen if any further issues are discovered.
