I have read this post: Can't compile plugin builder plugin in QGIS 2.4 (Windows)

But I couldn't resolve my problem.

I have already seen this post, looking for help. I can execute:

pyrcc4 -o resources_rc.py resources.qrc

But when I want to open my plugin made by Plugin Builder, it displays an error, saying that it is "broken".

enter image description here

  • Did you try using the make command for your plugin and then restarting QGIS? – Joseph Mar 31 '16 at 13:21
  • My OSGeo4W Shell doesn't recognise that command, that is why I am so dissapointed... :( I don't know what to do about that. I have tried to execute pb_tool but in my windows shell, I don't think it is going to recognise the code in the examples of the help documentation about pb_tool – user64823 Mar 31 '16 at 13:25

    Strange, maybe try reinstalling QGIS again using the OSGeo4W Network Installer? I recently had to reinstall QGIS (about 3 weeks ago) and the make method is still recognised. – Joseph Mar 31 '16 at 13:36

It seems your plugin doesn't have a metadata.txt file, could you have a look at the plugin folder to check if such file is present?

Make sure all your plugin files are inside your plugin folder, which in turn should be inside python/plugins/ folder, like this:

............(and all other files)

Sometimes, one can make a mistake and create an extra folder while choosing the directory to save the plugin, like this:

...............(and all other files)

Note the double NPlugin folder (python/plugins/NPlugin/Nplugin/...), which will make QGIS not to load the plugin. If that's your case, just leave a single NPlugin folder, from which QGIS can access all plugin files (such as in the first directory structure I mentioned).

If, on the contrary, your directory structure is fine, your plugin is missing a metadata file. Create a new file metadata.txt inside you plugin folder, containing information like:

# This file contains metadata for your plugin.         
name=My Plugin
description=My plugin does a lot of things

about=Plugin to do a lot of things


# Tags are comma separated with spaces allowed

# experimental flag

# deprecated flag (applies to the whole plugin, not just a single version)

Restart QGIS (or reload your plugin) and you should now get your plugin loaded.

  • +1, great answer! I will be writing a plugin soon so will definitely need to keep this in mind! – Joseph Mar 31 '16 at 14:00

    Just tried to create a test plugin and it happened to me, I created a double folder for my plugin, so I got the same error. Let's hope that solves the problem. – Germán Carrillo Mar 31 '16 at 14:02

    I have changed the folder, and made the resources_rc.py. Metadata is available. Then, I closed QGIS and opened again. I got this error again: No module named resources – user64823 Mar 31 '16 at 14:30

    Ok, that's another question. Your plugin (as it was created via Plugin Builder) expects the resources file to be named 'resources.py'. Try with such name. – Germán Carrillo Mar 31 '16 at 14:50
  • I used pyrcc4 -o resources.py resources.qrc and it worked. Thanks very much to everybody !!! – user64823 Apr 1 '16 at 7:28
