I reported this at GitHub a week ago (https://github.com/cocos-creator/engine/issues/4608). Unfortunately, I haven’t got any response.
We are using python3 as a default python interpreter, so we can’t upgrade Cocos Creator 2.1.x due to this bug. Can you please look into this issue?
@jare can tell us if python 3 is an issue. Thank you for creating the GitHub issue. I apologize for the delay our team is working hard on the next release.
Thanks @unace, we should work it out on Mac. See issue reply for details.
Thanks @jare.
