Bazaar

Error message with all command line commands

Asked by Bruce Graham on 2010-10-14

I just installed the standalone version of 2.2.1 on my Windows XP machine

For all command line commands of the form:

C:\Work\project\dev> bzr help
             or
C:\Work\project\dev> bzr version

I get the following:

"Unable to load plugin u'rebase'. It requested API version (2, 1, 0) of module <module 'bzrlib' from 'C:\Program Files\Bazaar\lib\library.zip\bzrlib\__init__.pyo'> but the minimum exported version is (2, 2, 0), and the maximum is (2, 2, 1)"

followed by the correct output.

Can I continue to use this version or should I revert back to 2.1.1?

Hi Bruce,

'bzr plugins -v' will show you where this out-of-date plugin is coming from. I think that bzr-rewrite is included in the standard windows installer, so you should just be able to delete the old plugin.

Bruce Graham (bgraham) said : #2

I moved the folder "C:\Program files\Bazaar\plugins\rewrite" to a temporary location on a network drive. I rebooted my system and I still get the error message that I quoted in my original post. The good news is that getting rid of the rewrite folder did not make things worse, but I think there is still a problem.

Vincent Ladeuil (vila) said : #3

Could you try to upgrade to bzr-2.2.1 which is the latest stable release (https://edge.launchpad.net/bzr/+download) and post the output of 'bzr plugins -v' if the problem persist ?

The plugins shipped with the installer should not exhibit such a behaviour, so it may come from a plugin you installed yourself. If that's the case, you should be able to identify the faulty plugin by searching in the 'plugins' sub-directory of the bazaar configuration directory found in the output of 'bzr version'.

Vincent Ladeuil (vila) said : #4

Bah, forget the first paragraph of my previous answer, you've already upgraded.

Bruce Graham (bgraham) said : #5

As far as I know I have not installed any plugins "myself" that were not part of a prepackaged installer. I started using Bazaar in December 2009 and this is either the third or forth upgrade that I have installed. I could also try removeing the "rebase" plugin since that is the one the message seems to be complaining about. I'm confused by the first response that said to remove "rewrite". Did that poster mean "rebase" and his fingers and brain were disconnected so it came out "rewrite"?? I'm just sayin', but what do I know?

Bruce Graham (bgraham) said : #6

Strange as it may seem I think my "off the wall" suggestion of 6 minutes ago was the ticket. When I removed the "rebase" folder from:
C:\Program Files\Bazaar\plugins the problem appears to have gone away.
In short the plugin to remove is "rebase"
NOT "rewrite"

Although there seems to be a suggestion that non of them are actually required anymore. Is this correct?

Best Vincent Ladeuil (vila) said : #7

bzr-rebase has been renamed bzr-rewrite, hence the problem you're encountering and the first remark.

Can you try to run 'bzr plugins -v' and post the result ?

This should list all the plugins that load correctly and from where they are loaded. From there we may guess where the faulty plugin is located.

Vincent Ladeuil (vila) said : #8

Yes, none of this should have been needed, there were early reports about such problems around the time the plugin was renamed but the installers are since supposed to take care of that.

Anyway, martin said: "so you should just be able to delete the old plugin" the *old* name was 'bzr-rebase' so indeed he told you to remove the 'rebase' directory containing the old plugin.

Glad to see you're out of trouble now.

Thanks Vincent Ladeuil, that solved my question.

Marius Kruger (amanica) said : #11

As far as I know, it is recommended that you first uninstall your current bzr before installing a new version.
That may have prevented this from happening.

Bruce Graham (bgraham) said : #12

@Marius
Thank you for that observation; it appears to be correct. I removed the current installation and reinstalled it and the problem did not occur. When you only upgrade stuff occasionally it is easy to forget things like this. Some packages require it and some don't. Some will warn you and others won't -- life goes on.
