Installation error

[BernieTGN]

Hi,
I am trying to install on Windows 10 with the following statements:

conda create -n jupyterlab-debugger -c conda-forge xeus-python=0.8.0 notebook=6 jupyterlab=2 ptvsd nodejs
conda activate jupyterlab-debugger
jupyter labextension install @jupyterlab/debugger

but I got the following error message:

"_(jupyterlab-debugger) C:\Users\Patricia>jupyter labextension install @jupyterlab/debugger

I would appreciate your help to know what I am doing wrong.

Thanks,

ModuleNotFoundError: No module named 'jupyter_server'

It looks like an issue when creating the environment?

As an alternative we would suggest using the 3.0 release of JupyterLab, which now includes the debugger by default.

Installation steps are also simplified and don't require nodejs:

conda create -n jupyterlab-debugger -c conda-forge xeus-python=0.9 jupyterlab=3
conda activate jupyterlab-debugger
