Cannot find module grep

[Tim Powell]

I tried getting bzr-grep working with bzr 2.5. Following the instructions in the INSTALL file, I moved the directory to the plugins directory (renamed as grep).

bzr help grep works fine, so the files are in place.

However, actually trying to use the command causes this error:

bzr: ERROR: No module named grep
You may need to install this Python library separately.

I think this is caused by using lazy_import to get the grep module when it isn't a system module. It's a file in the plugin. I moved the import grep line in __init__.py outside the lazy_import call and all seems to be working now.

Prior to my change, bzr log gave this traceback:

What version of bzr-grep are you trying? For bzr 2.5 you need the fix for relative imports from r147.

I grabbed the tar from the main bzr-grep page. It says Latest version is 0.4.0-final.

After your comment, I pulled the trunk from launchpad and installed it again.

I confirm that bzr grep 0.5.0dev works as expected.

Thanks for the help!

Great, I'm glad that worked for you. Seems like bzr-grep needs a new release.
