How to use jupyterlab-dash in an offline environment

[chaisaijuice]

Hello,

I want to use Dash with interactive coding in Jupyterlab within an offline Environment behind corporate Firewall. I already installed Dash and when I publish an App the Renderer Works.

Now I wanted to install the jupyterlab-dash and I need your help. This are my installed dash-components:

I was able to use pip install jupyterlab>=1.0" jupyterlab-dash with our local repo. But I'm running into Problems when trying to use jupyter labextension install jupyterlab-dash:

When I look at the log file I can see that it checked if i have nodejs installed (which I don't), it then tries to install node.js but isn't able to in this offline Environment. I also don't have npm installed.

Is there anyway to install jupyterlab-dash in an offline environment or isn't it possible to provide all dependencies offline?
