I found that i need to ` install this package , however i am unable to install it, i have tried:

npm i @pyviz/jupyterlab_pyviz

  File "<ipython-input-21-385fb6412a4c>", line 1
    npm i @pyviz/jupyterlab_pyviz
        ^

Just released pyviz_comms 2.0 which automatically bundles the JupyterLab extension. Simply upgrade with pip install pyviz_comms --upgrade or conda install -c pyviz pyviz_comms.
