Revision history [back]

Based on the paths above it looks like you may have a python installation shadowing the system python installation used by ROS 2.

The /home/debian/.local paths in your error output are what suggest this to me. I've had issues in the past with pip packages I've installed in .local interfering with system-wide packages. I tested by moving ~/.local to ~/.local.disabled and trying again in a new shell to find my command successful. I never resolved the issue with overlapping packages in .local and ended up just uninstalling packages that were there.
