Problem description
Problem
Most times when opening a python file and thereby loading pylsp, it crashes, trying to load a module named pylsp.plugins.rope_rename.
In some rare cases pylsp started fine, without any errors, though I couldn't figure out what caused it to occasionally work.
This issue also occured to others in the last few days, as can be seen in this Reddit thread.
Reason
The file .../mason/packages/python-lsp-server/venv/lib/python3.11/site-packages/pylsp/ is in fact missing inside the pylsp installation provided.
Reinstalling pylsp via mason didn't fix it.
Quickfix
Retrieving the file from this python-language-server repo (not sure if official) and manually adding it to the above directory fixed the problem for me and at least one other user from the Reddit thread.
Even after the quickfix, it still occasionally (seemingly randomly) crashes with ModuleNotFoundError: No module named 'pyls'.
Expected behavior
pylsp should start quietly and provide language features.
Steps to reproduce
- Install pylsp using mason
- Setup pylsp using nvim-lspconfig
- Open a python file
