Something like the following:
conda create -n jupyterlab -c conda-forge jupyterlab=3 -y
conda activate jupyterlab
# open JupyterLab
jupyter lab
You might also want to check the order of the configuration folders returned by the jupyter --paths
command. There is more info about this in: Jupyter Paths priority order
Just to check whether if there is a page_config.json
file in PREFIX/etc/jupyter/labconfig/
(or in ~/.jupyter/labconfig
) that might have the terminalsAvailable
setting disabled.
