Getting following error during pip install keepercommander

  [stdout]
  pkg-config is required for building PyAV

help: av (v12.3.0) was included because keepercommander (v16.11.19) depends on aiortc (v1.9.0) which depends on av

[sk-keeper]

keepercommander package references aiortc one.
Unfortunately this third-party package is not compatible with Python3.13 yet.

The commander team will make this dependency optional in the next release (probably today Dec 6th)

[sk-keeper]

v16.11.20 has been released.
It supports installation on Python3.13
