Configuration | Documentation | Poetry - Python dependency management 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. You can navigate this Python tutorial using the buttons at the top and bottom of the articles. While the dependency resolver at the heart of Poetry is highly optimized and should be fast enough for most cases, with certain sets of dependencies it can take time to find a valid solution. but it would be really nices if this could "just work" in a way that consistent with general poetry usage. adding a --name option doesn't seem like it would rupture spacetime.
