Hello Henri, Could you please try running the command:
jupyter lab build to see if it resolves the issue? It looks like the static built resources that JupyterLab needs don't exist where it expects to find them. If that does **not** fix the problem, can you confirm whether running just the plain launch command: jupyter lab successfully launches JupyterLab? Cheers! -Darian On Wed, Jul 17, 2019 at 7:36 AM Henri Girard <[email protected]> wrote: > Hi, > > I can't no more use jupyterlab in sage -n=jupyterlab, I got this error > message ? > > Cannot find template: "error.html" > > In "/home/pi/sage/local/share/jupyter/lab/static" > > > I am on ubuntu 19.10, it used to work and suddenly stop...
