$ 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.
Usually you want the stubs to be installed as part of the development dependencies.
pyproject.toml does not allow to pass config-settings to requirements.
If you need specific versions of some libraries you can use a requirements.txt file instead, which
allows to pass config-settings per requirement as of pip >= 23.1.0.
