can you do this https://flet.dev/blog/flet-new-packaging-pre-release#light-client-for-linux?

pip uninstall flet-desktop-light --yes
pip install flet-desktop==0.27.4

[MHamed72]

Thank you for the answer. I perform the uninstall ans the install ; I get ModuleNotFoundError: No module named 'flet_desktop' . Here is the result to pip list |grep flet
flet 0.27.4
flet-audio 0.1.0
flet-cli 0.27.4
flet-desktop 0.27.4
flet-web 0.27.4

I have to uninstall all flet component and reinstall it again to remove missing module error.
Please note that: I test the same code using flet-audio; It works without problem on both Windows and Linux Lite.

I have to uninstall all flet component and reinstall it again to remove missing module error.

Does it work now?

[MHamed72]

I return to initial state. The unknown module:audio when run flet (flet run).
Please note that trying with flet run -w wasn't good in audio, but I don't get that error

Try doing it from scratch, in a clean virtual environment. On Linux pip install flet[all] installs flet-desktop-light without audio and video support.

To fix that you need to pip uninstall flet-desktop-light and then install flet-desktop.

[MHamed72]

Here is the step:

• conda create -n test_flet -->create new environment

• conda activate test_flet --> activate the environment

• pip install flet[all]

• pip list |grep flet
  flet 0.27.4
  flet-audio 0.1.0
  flet-cli 0.27.4
  flet-desktop-light 0.27.4
  flet-web 0.27.4

• pip uninstall flet-desktop-light

• pip install flet-desktop

• pip list | grep flet
  flet 0.27.4
  flet-audio 0.1.0
  flet-cli 0.27.4
  flet-desktop 0.27.4
  flet-web 0.27.4

• flet run --> get the 1st result `unknown package:Audio
