For python packages it doesn't matter at build time, it's more about if it's needed at build time (native-inputs) or if it's needed to run the python program (propagated-inputs) since we don't have a good way to tell python to keep a reference to other python packages. > ~~~~START~~~~ > running install_egg_info > Copying jupyterlab_server.egg-info to > /gnu/store/2h44ldpcqqd0q7hqpbcqdavcnbjsibfb-python-jupyterlab-server-1.2.0/lib/python3.8/site-packages/jupyterlab_server-1.2.0-py3.8.egg-info > running install_scripts > phase `install' succeeded after 0.3 seconds > starting phase `wrap' > find-files: > /gnu/store/2h44ldpcqqd0q7hqpbcqdavcnbjsibfb-python-jupyterlab-server-1.2.0/bin: > No such file or directory > find-files: > /gnu/store/2h44ldpcqqd0q7hqpbcqdavcnbjsibfb-python-jupyterlab-server-1.2.0/sbin: > No such file or directory > phase `wrap' succeeded after 0.0 seconds > starting phase `check' > running "python setup.py" with command "test" and parameters () > running test > running egg_info > writing jupyterlab_server.egg-info/PKG-INFO > writing dependency_links to jupyterlab_server.egg-info/dependency_links.txt > writing requirements to jupyterlab_server.egg-info/requires.txt > writing top-level names to jupyterlab_server.egg-info/top_level.txt > reading manifest file 'jupyterlab_server.egg-info/SOURCES.txt' > reading manifest template 'MANIFEST.in' > warning: no previously-included files matching '*~' found anywhere in > distribution > warning: no previously-included files matching '*.pyc' found anywhere in > distribution > warning: no previously-included files matching '*.pyo' found anywhere in > distribution > warning: no previously-included files matching '.git' found anywhere in > distribution > warning: no previously-included files matching '.ipynb_checkpoints' found > anywhere in distribution > writing manifest file 'jupyterlab_server.egg-info/SOURCES.txt' > running build_ext > test_get (jupyterlab_server.tests.test_settings_api.SettingsAPITest) ...

Assuming WorkspacesAPITest does actually have an attribute named lab_config then you'll want to add the installed package to the python path during the check phase. There are a number of packages which do this. I can never remember the syntax so I always grep for 'add-installed-pythonpath' when it comes up. > I guess I will summarize everything in the end and put it in a > repository as a kind of "guide", so that others can use it or learn from > the process.
