KDEnlive - Export not possible, Python error

Morning all,

i am trying to export an edited video from KDEnlive.
After fixing an issue that pip3 was missing i ran in another problem which i hve no idea how to solve it.

So far everything goes fine, but if i come to exporting the video, i am getting this error:


Klicking ok brings me to the export settings, whenever i hit the reload button, the python error appears again:


I fixed that issue also by installing the python setuptools, but there is still this error which doesnt go away, even after hitting the “instal dependencies” button:

I have tried to install it also via “pip install opentimelineio” in a terminal, but it throws a similar error:

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for opentimelineio
Failed to build opentimelineio
ERROR: Could not build wheels for opentimelineio, which is required to install pyproject.toml-based projects

Any idea how to get this resolved would be appreciated

There was a huge python update today.

Also, opentimelineio is in the repos and up-to-date, including dependencies.

Why would you want to build it yourself?

sudo pacman -Syu opentimelineio …and reboot.


Both has been installed. There is no update waiting and opentimelineio was installed exactly as you described.

Error persists
