Jupyterlab 0.31.8
Ubuntu 14.04
Plotly 3.0.0

I’m trying to install the Plotly jupyterlab extension.

Running

jupyter labextension install @jupyterlab/plotly-extension --debug

results in

What I tried was the standard recommendation found here https://github.com/jupyterlab/jupyter-renderers/tree/master/packages/plotly-extension

What should I do differently?
