Are you trying to run Flet from sources, not with pip install flet?
Running from sources is used mostly when developing Flet itself.

[Wanna-Pizza]

Okay. I installed flet with pip install flet. Now the new problem is occurs.

When I run "poetry run flet run -w -p 8550 .\hello.py" there is no attribute 'bgblur'

But I added this new attribute in my flet project.

Im using Visual Code.

So, can you help or explain what I can do with that?

I think poetry run flet run uses the global Flet, but not the one in the project. Accordingly, even when I do a Build or update everything - still the error that the attribute is not found
