gedit: Could not find loader 'python' for plugin

[Richard Eszes]

When I try to enable some plugin in gedit (3.8.3-0ubuntu3), I can error message such this:

(gedit:11688): libpeas-WARNING **: Could not find loader 'python' for plugin 'sourcecodebrowser'

Operation system: Ubuntu 13.10 64 bit

Status changed to 'Confirmed' because the bug affects multiple users.

Same here, sourcecodebrowser plugin worked on 13.04, no longer works on 13.10. When I start gedit from cmdline I get the same error as OP upon attempting to enable the plugin. Seems to be a similar issue with many gedit plugins, but apparently all with different solutions. Many have recommended editing the .plugin file and changing Loader=python to Loader=python3, which seems to get us past the "could not find loader" problem, but still doesn't work:

Traceback (most recent call last):
  File "/home/rob/.local/share/gedit/plugins/sourcecodebrowser/__init__.py", line 1, in <module>
    import plugin
ImportError: No module named 'plugin'

Also just for the whynot I tried python2 and got "Could not find loader 'python2' for plugin 'sourcecodebrowser'"

I do have all 3 pythons...

$ which python
/usr/bin/python
$ which python2
/usr/bin/python2
$ which python3
/usr/bin/python3

Do you get the issue if you install gedit-source-code-browser-plugin rather than using your local copy?

[rg (rob-themayfire)]

Yes, same issue after installing via gedit-source-code-browser-plugin (and removing ~/.local/share/gedit/plugins/sourcecodebrowser*). Upon attempting to enable the plugin I get the same error reported by OP. Changing the Loader value in /usr/lib/gedit/plugins/sourcecodebrowser.plugin has all the same effects as I described above.

[Sebastien Bacher (seb128)]

not sure what's the issue there, could be a libpeas bug ... I can't confirm though, it works here

[Huan Zhang (victzhang)]

My patch should solve this problem. Please test it.

Thanks,
Huan

The attachment "Patch for gedit plugin "sourcecodebrowser", tested on gedit 3.8.3 and Python 3.3.2" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

[rg (rob-themayfire)]

SUCCESS! Applying victzhang's patch solves the problem and the plugin is now working again.

[Sebastien Bacher (seb128)]

Could you explain the changes you did and send those upstream as well?

[Huan Zhang (victzhang)]

This plugin is written for Python 2, but since gedit 3.8, only Python 3 plugins are supported. So some small changes are required.

Send the patch to https://github.com/Quixotix/gedit-source-code-browser/issues/25, but I am not sure if it will be updated soon since there has not been any no active developments in this repository for two years.

Forked gedit-source-code-browser, committed patch, submitted pull request. FWIW.

[rg (rob-themayfire)]

I'm new around here, but I'm not sure Fix Released is the proper status yet for this bug. I am not the maintainer of this plugin, I've only applied the patch on a fork and submitted a pull request to the maintainer (Quixotix), who I assume will need to merge the change before this fix is "released"..?

reassigning to gedit-source-code-browser

I notice that Debian has already patched this
http://metadata.ftp-master.debian.org/changelogs//main/g/gedit-source-code-browser-plugin/gedit-source-code-browser-plugin_3.0.3-3_changelog via http://packages.debian.org/hu/jessie/gedit-source-code-browser-plugin

This has been imported into trusty

I have downloaded this version from:

https://launchpad.net/ubuntu/trusty/+package/gedit-source-code-browser-plugin

And given it a quick try and seems to work fine - could someone verify ?

[Isiah Meadows (impinball)]

victzhang's patch worked for me (on GNOME 13.10). It definitely should be pushed upstream.

[James Cowgill (jcowgill)]

Fixed in version 3.0.3-3 (trusty)

[Luis Alberto Pabón (copong)]

This is again a thing on 16.04

On Ubuntu 14.04 :
