Can't import via OpenTimelineIO

I’m new to Kdenlive, and I’m trying to use OpenTimelineIO to import a .XML from DaVinci. But I get an error message every time I try File>OpenTimelineIO Import:

Could not find “otioconvert” script although it is installed through pip3.

Please check the otio scripts are installed in a directory listed in PATH environment variable

Sometimes it prompts me to configure my OpenTimelineIO setup, but then it shows this:

Everything is configured: OpenTimelineIO 0.15.0

Defaulting to user installation because normal site-packages is not writeable

Requirement already satisfied: opentimelineio in /Users/mulcahey/Library/Python/3.8/lib/python/site-packages (0.15.0)

Requirement already satisfied: pyaaf2<1.7,>=1.4 in /Users/mulcahey/Library/Python/3.8/lib/python/site-packages (from opentimelineio) (1.6.0)

Anyone know how to fix?

Thank you!
