Expected Behavior

Expected to be able to install locally with editable mode. I can install it normally via pip install opentimelineio. I’m trying to figure out what’s going on. There’s a .egg-link file in site_packages which seems to be correctly pointing to the root. Contents of the .egg-link:

/Users/pedrolabonia/dev/otio/OpenTimelineIO
.

The other way is to simply copy the .so into src/py-opentimelineio/opentimelineio and add src/py-opentimelineio to your PYTHONPATH.

1. python setup.py build_ext
2. Copy copy the .sos into src/py-opentimelineio/opentimelineio
3. Set PYTHONPATH to src/py-opentimelineio

[JeanChristopheMorinPerso]

I personally don’t think it should go into the contributing guide. It’s way too hacky. I also wouldn’t add this solution to the setup.py script because it wouldn’t work for developers working on the extensions (_otio and _opentime).
