Installing LSP unsuccessful. Error: 500 (Internal Server Error)

Description

This seems like a great extension to me, but i can get it to install/work properly. 😃

I installed it via conda, and all seems to resolve OK.

(base) C:\>conda install --insecure -c conda-forge python-language-server r-languageserver
Collecting package metadata (current_repodata.json): done
Solving environment: done

But when I try click ‘install’ within the extension pane in Jupyter Lab: I first get the Server Companion warning: I click ‘OK’. Then it gives me an Internal Server Error I can’t find anything useful in the documentation about this.

Thanks for your reply. I can understand the complexity, and that this might not be the right time to implement this yet. I really value the effort you guys put in, also in you spare time. And hope this can be realized at some point in the future. Cheers!

Hi bollwyvl, I now installed the newest version of nodejs (13). But that does not seem to work due to a conflict with npm.

(base) C:\>conda list nodejs
# packages in environment at C:\ProgramData\Anaconda3:
#
# Name                    Version                   Build  Channel
nodejs                    13.0.0                        1    conda-forge

(base) C:\>jupyter labextension install @krassowski/jupyterlab-lsp
An error occured.
ValueError: "@krassowski/jupyterlab-lsp" is not a valid npm package
See the log file for details:  C:\Users\XXXXXX\AppData\Local\Temp\jupyterlab-debug-tcgdyvs1.log

Edit: Downgraded to NodeJS version 10:13 and now this error is resolved.
