This is still a work in progress. Where did you get the code, how did you install the code, what os are you on, those kinds of things, would help.

I use Mac OS, I do everything in order as it is written in readme:

install the extension:

jupyter labextension install @krassowski/jupyterlab-lsp

install servers for languages of your choice. Below are examples for Python (with pyls) and R (with languageserver):

pip install python-language-server[all]

next, I go to the folder

/Users/sergejsuhinin/anaconda 3/lib/python 3.7/site-packages/jupyterlab/staging

create servers.yml file:

langservers:
python:
- pyls
R:
- R
- --slave
- -e
- languageserver::run()

and execute the following commands

npm install
npm run build
jupyter labextension link .

this is where the problems arise

node_modules/jsonrpc-ws-proxy/dist/server.js: No such file or directory

[bollwyvl]

Did you install the python portion with pip/setup.py?

[krassowski]

For normal installation (jupyter labextension install @krassowski/jupyterlab-lsp) you should not execute the following commands:

npm install
npm run build
jupyter labextension link .

These are for development install (please take a careful look at the instructions in the readme).

The readme does not say that you should go to the staging directory, but rather that the node_modules/jsonrpc-ws-proxy/dist/server.js is likely to be located there. The servers.yml should not be created in the staging directory but in your current project directory.

And, finally, as @bollwyvl, mentioned the next version (due to be published next month) will remove the necessity to configure the servers.yml - stay tuned.

Thanks, figured it out. But now the error crashes

[krassowski]

Could you please paste the exact command you used and the contents of your servers.yml file - this might help to decipher the error message.

[krassowski]

Closing, as we no longer use jsonrpc-ws-proxy.
