How to handle "ModuleNotFoundError: No module named 'pylsp.plugins.rope_rename'"

[buhtz]

Hello,

I was updating all my Emacs (29 from Debian 12 backports) packages after a while and no got this error. After doing some research it seems that rope-support was removed from pylsp.

[eglot] (warning) [eglot] -32602: ModuleNotFoundError: No module named 'pylsp.plugins.rope_rename'

I installed it explicit via pip install -U pylsp-rope but nothing changed.
OK, I am also fine with just disabling rope in my setup. But I don't know how. I don't see "rope" in my init.el.

My (reduced) init.el is ~240 lines long. Not sure if it make sense to post it here.

Any suggestion how to go further with analyzing this?

I encountered this pylsp crash after a recent nvim "!Lazy sync" ... command, even after updating everything else. The LSP stacktrace I got is below, pretty-fied and with my home path replaced by $HOME. This is a hard crash that prevents the LSP from launching and attaching to the buffer. Are there any suggested workarounds while a fix is released? 🤔

I'm having the same issue with neovim after a recent update of packages and lsp servers on my system. Could this be related to #515?

Here is a traceback that might help

magically, just adding an empty rope_rename.py in plugins/ makes it all work

[php1ic]

Adding the file works for me. Thanks @dcherian!

[ghost-in-the-zsh]

The issue seems to have been resolved. I updated yesterday, without manually adding any files, and I no longer see the error.

[php1ic]

Strange, I still see the error if I remove the rope_rename.py file.

What did you update? I've got all the latest updates for packages installed via Lazy and I use Mason for my LSP servers and that is still showing 1.12.0 for python-lsp-server with no available updates.

I stand corrected... after updating this morning, I now see the crash again, but it was definitely not broken when I posted last time. Someone seems to keep messing up and there's no official response in this thread, either...

BTW, if anyone's wondering where, exactly, you should touch rope_rename.py, it should be under $HOME/.local/share/nvim/mason/packages/python-lsp-server/venv/lib/<your-python-version>/site-packages/pylsp/plugins/

Just posting here to bump it, because it started happening again last Friday and is still present today, as of this writing. The same solution still applies, though. Maybe it's time that the plugin import is at last placed within a try/except block or something by dev(s).

[ElricleNecro]

This is still happening, any news?

All I can say is that I've not run into the problem again since the last time I manually applied the fix(es) described above.

[schlegan]

I haven't run into this problem on linux with the newest version, but on windows I had a case where I, accidentally, had installed the server via winget and via pip at the same time and this error popped up.

After removing the winget installation, it vanished.

I just fix this error by uninstalling an old version python-lsp-server in user path $HOME/.local/lib/python3.x, maybe pylsp packages in mason venv have conflicts with it .

$ pip list | grep python                                                                                                                                    
python-lsp-jsonrpc    1.0.0
python-lsp-server     1.7.1
$ pip uninstall python-lsp-server

and I reproduce this error by installing old version python-lsp-server and restart neovim

pip install python-lsp-server==1.7.1 --user

my mason pylsp venv package version

source $HOME/.local/share/nvim/mason/packages/python-lsp-server/venv/bin/activate && pip list | grep python     
python-lsp-black      2.0.0
python-lsp-jsonrpc    1.1.2
python-lsp-ruff       2.2.2
python-lsp-server     1.12.2

Hopefully, my approach can be helpful.
