SyntaxError: invalid syntax

Answer 1

You seem to have installed the JWT package, which is only compatible with Python 3.4+. The rest-framework-jwt app is trying to import that rather than PyJWT which is compatible with 2.7.

Remove that installation with pip uninstall jwt. Once removed you'll want to install PyJWT like so:

pip install PyJWT
