pip install pygobject-stubs

Some libraries exist in multiple versions like Gtk3/4. As both libraries are currently imported under the namespace Gtk only stubs for one can be installed.

You need to decide this at install time either by using the --config-settings option with pip

$ pip install pygobject-stubs --no-cache-dir --config-settings=config=Gtk3,Gdk3,Soup2

or by setting the PYGOBJECT_STUB_CONFIG env variable

$ PYGOBJECT_STUB_CONFIG=Gtk3,Gdk3,Soup2 pip install --no-cache-dir pygobject-stubs

If no configuration is set, the most recent version of each library is installed.

--no-cache-dir is only necessary on subsequent reinstalls, otherwise the stubs will not be rebuild and a cache of a previous installation is used.
