.lsp-symlink doesn't seem to work

[tsjk]

Description

I use jupyter/tensorflow-notebook:python-3.10 with jupyterlab 3.6.5, jupyter_server 2.7.0 and jupyterlab_server 2.24.0.

Reproduce

1. ln -s / "${NB_HOME}/.lsp-symlink"
2. Open your ipynb notebook
3. Click on an external function call and navigate (ctrl-b)
4. Observer error

e.g. (for gc.enable())

However, if I show hidden files and navigate to .lsp_symlink/opt/conda/lib/python3.10/site-packages/jedi/third_party/typeshed/stdlib/3/gc.pyi' I can open the file.

On a side note. Navigating to functions in .py-files located in the current working directory doesn't work either. There it says that "No jump targets found". E.g.

import my_helper
my_helper.init()

where my_helper.py is located in the same directory as the notebook. Navigating to my_helper.init() doesn't work (and yes, the function exists). This is likely another problem.

@tsjk hi, have you solved this error? I also met it.

@Mrfranken - no, I have not... :\
