Python language server breaks autocomplete on Python 3.11 #959

Open ptr33 opened 1 year ago

ptr33 commented 1 year ago

Hi,

I installed python language server which requires jedi==0.17.3 which breaks my autocomplete in Python 3.11 in a Jupyterlab notebook. Pressing \<tab> in a notebook generates following errro:

NotImplementedError: Python version 3.11 is currently not supported.

I used following docker container:

docker run --rm -it -p 8888:8888 ghcr.io/ptr33/jupyterlab:3.11

and open http://localhost:8888/jupyter

In this docker container after running

pip uninstall python-language-server 
pip install jedi==0.18.2 

autocomplete works again.

Any idea to use the language server with Python 3.11?

Thank you ptr33

There is no 0.17.3 release of Jedi, at least not recorded in the changelog, but if you are using 0.17.2 then it came out over 2 years before 3.11, that release of Jedi won't support Python versions beyond 3.9. Version support for Python version 3.11 is not listed in the most recent update of Jedi, but it came out more recently than version 3.11 so your best bet is either resetting to Python 3.9 for use with Jedi 0.17.2, or using 0.18.2 with Python 3.11. I doubt that has 3.11 support though tbh

Hi @Shabbyshambles, thank you for your comment - currently python-language-server does not work together with the latest jedi release (0.18.2 from 21 Nov 2022 https://pypi.org/project/jedi/0.18.2/#history) - is it possible to make a new release of the python-language-server which uses this version?

Thanks ptr33

Yes, waiting for the support of Python version 3.11. Thanks! LSP :: Error from the Language Server: NotImplementedError: Python version 3.11 is currently not supported. (Invalid Parameters)
