Ubuntu – No JS module ‘tweener’ found in search path, Gnome shell extension error on Ubuntu 20.10

20.10gnomegnome-shell-extension

Today I upgraded Ubuntu 20.04 to Ubuntu 20.10 and there is problem in one of the extensions in Gnome shell extensions.

The Extension Panel OSD giving the error "No JS module 'tweener' found in search path".

How to resolve this?

Best Answer

The tweener module has been moved to a new path, from imports.ui.tweener to imports.tweener.tweener. In the exention's repository, somebody already created a merge request to merge the necessary changes into the code, but the extension's developer hasn't merged it yet.

You can either wait until the developer does the change and puts out a new version of the extension, or - if you feel comfortable with it - change the import path in your local copy of the extension yourself. You can look up in the merge request what to change.

Ubuntu – Can’t Right-Click on Gnome-Shell Panel to Add Extension

you can't add extensions by right clicking the panel. You have to create a dir in ~/.local/share/gnome-shell/extensions/extension_name@your_host

and create there 2 files: extension.js and metadata.json

and add code to whatever you want to add onto panel to extension.js and some info into metadata.json

in gnome-shell 3.0.x in .js you have to add function main() { } in gnome-shell 3.2.x: function enable() { /* code to execute on enabling this extension */ } function disable() { } and function init() { }
