dstandish commented on issue #5857: [AIRFLOW-5251] add missing typing-extensions dep for py37 URL: https://github.com/apache/airflow/pull/5857#issuecomment-546574664 It seems this may be causing a problem with alembic. Since you run alembic from `<root>/airflow` directory, when it tries to import `typing_extensions`, it then tries to open `typing`, which resolves to this typing module and not the actual one. That's probably confusing, but basically if I run `alembic revision -m "something"` I get import error from tying module. If I run from repo root (specifying config file and changing `script_location` I don't get this error. (i get `ERROR - Multiple heads are present;`)
