Impossible to install an extension

Hello,

I have successfully installed jupyterlab-execution-time extension on a computer (jupyterlab desktop v3.6.3-1), however on the second computer I can’t with the issue: Jupyterlab version must be >=3.4.6 and <3.5.

So I try to download the only version compatible of jupyterlab desktop: [v3.4.6-1].

However for some reason there is no extension manager icon on the left side panel and I don’t find any other way to install it.

Could you please help me, either by help me using extension manager on the 3.4.6 or by solving the issue on the 3.6.3-1?

Also, when I try to update the jupyterlab-execution-time on the computer that is working, I have: Error when performing an action.

Reason given:

Error: ERROR: Could not open requirements file: [Errno 13] Permission denied: ‘C:\Users\Thomas\AppData\Local\Temp\tmpolqch0cd’

in fact this folder does not exist, if that can help

Thanks a lot

When you run the command ‘jupyter --list’ does it list extension manager?

I’m wondering if you need to manually install it

I’ll tell you when I’ll got the second computer back.

However it doesn’t seem to achieve the thing you want in the one that work.

It gives me:

My bad, turs out the command is ‘jupyter labextension list’,

when I run it, It shows @jupyter-widgets/jupyterlab-manager v5.0.10 enabled OK (python, jupyterlab_widgets), which tells me I have this extension manager installed.

If you find it then next step would be to check if you enabled it in the app. I would go to settings → settings editor → extension manager and click on enable checkbox (this is for the latest version, menu options might be different, depending on the version)

something like this:
