Can you describe what issues you've had with NPM that you haven't had with Poetry? In principle, they should be doing the same thing - both use a per-package environment and a lockfile, allow you to run commands in the environment, ensure the checked-in dependencies remain in sync with the local dependencies, etc. The main difference is that Python's ecosystem only allows one version of a dependency to exist at a time, but Node's ecosystem can handle multiple coexisting dependencies.
