In addition to what @ulgens mentioned, a use case would be having a shared project with shared modules and dependencies in order to guarantee the different services/projects are using the same versions of the shared dependencies. In the past I would simply do pip install -e project1 project2 but that does not work without a setup.py. Python-poetry error: Setting settings.virtualenvs.in-project does not I also have to be extra careful about security leakages with development packages on a production server. privacy statement.
