Is it possible to install QGIS Plugins with Python code?

I would like to be able to provide users who have a basic QGIS image served up to them, to be able to quickly install all their required plugins with a tailored Python script to save them manually installing each via the usual menu route, one at a time.

I cannot see any code that runs in logs after a successful plugin install and no clues online in my searches.

    you could just unpack a zip file in the packages folder – Ian Turton Jun 26 '20 at 9:36
  • Thanks - unfortunately, there is no access to the install area as a user so cannot refer to specific locations that would typically be on a C drive. Does that make sense. Installing with QGIS via the usual route is fine, but I don't have access to do things like that unfortunately. I was hoping I might be able to have the users run their own little Python snippet to set up favourites (done) and add Plugins in one quick hit. – Graeme Jun 26 '20 at 10:00

    I guess there are several ways to do this. If you want to install public plugins (registered in the QGIS plugin repo), then you could use the pyplugin_installer instance. Quick example: import pyplugin_installer | pyplugin_installer.instance().fetchAvailablePlugins(False) | pyplugin_installer.instance().installPlugin('asistente_ladm_col') You can read the installer.py code to get some inspiration. – Germán Carrillo Jun 26 '20 at 12:02
  • Thank you Germán - that is exactly what I needed, – Graeme Jun 26 '20 at 13:22
  • If you don't mind, I'll elaborate more for answering this question, as it can be the reference for other people searching how to install a plugin via Python. I'll cover more cases. – Germán Carrillo Jun 26 '20 at 16:51

The answer is yes.

Installing a plugin from the QGIS Plugins Repository

This is how you can install a plugin called loadthemall:

import pyplugin_installer

Plugin keys correspond to their folder names. Some examples: AppendFeaturesToLayer, asistente_ladm_col, loadthemall, profiletool.

As last resort, you could get plugin keys in this way (if you haven't called fetchAvailablePlugins, it will give you installed plugin keys):


Installing a plugin from ZIP file


Uninstalling a plugin

  • This fully solves my issues, and this in particular has helped with the issue of how to call the individual Plugins: pyplugin_installer.installer_data.plugins.all().keys() – Graeme Jun 29 '20 at 8:45
