Loading widget forever running

Note : I have npm with vuejs3 already installed (not in this directory) can it causes problems ?

Great! As far as I understand all your issues are resolved? I will close this ticket, feel free to re-open or create a new issue if other problems occur.

Regarding the 404 error, a bit more explanation: Lets say this is our project structure:

package
|-__init__.py
|-sub.py

when you do a import package with brython, it cannot know in advance if package is a directory or a file, so it tries to access package.py if it gets a 404, so it next tries to access package/__init__.py which succeeds.

Lets look at the vuepy project structure

vue
|-bridge
   |- <multiple .py files>
|-decorators
   |- <multiple .py files>

You get the 404 errors when brython tries to load a module which is a directory (vue, bridge, decorators)

So nothing to worry about the 404, it is part of how brython works.

After configuring vuepy.yml in the new format and reinstalling master, the results are as follows.

I think this is probably normal and does not need to be noticed.

So far all my problems have been solved perfectly.

Thx. Have a good day!
