jupyterlab error

[Henri Girard]

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... I installed it this way

sage -sh

then pip install jupyterlab --user --upgrade

exit

Any help ?

Regards

Henri

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!

Hi Darian,

Thank first :)

jupyter lab build do the job

jupyter lab runs but inside I haven't choice for sage ?

I compiled sage-8.8 then I linked it to /usr/bin/sage so I can use it as system wide.

After I installed jupyterlab with pip in sage (as I always do for a long times)

sage -sh

pip install jupyterlab --user --upgrade

in a console jupyter lab build (if I don't sudo -H it doesn't have permissions ?

in a sage -sh console it doesn't here is the error message ?

(sage-sh) pi@pc:~$ sudo -H jupyter lab build
Traceback (most recent call last):
  File "/usr/local/bin/jupyter-lab", line 7, in <module>
    from jupyterlab.labapp import main
ModuleNotFoundError: No module named 'jupyterlab'

 

I guess it's a problem of permissions ? But I don't know how to set it ?

Cheers

In fact I found the problem, I had to make a sage kernel in jupyter kernels

I thaught it was automatically done by sage / jupyter

"display_name": "sage",
 "argv": ["/home/user/sage/sage", "--python", "-m", "sage.repl.ipython_kernel", "--matplotlib=inline", "-f", "{connection_file}"]
}
