   Thank you for re-opening this issue.  I've installed the master version:
   
   ```
   [airflow@ip-172-20-2-227 airflow]$ airflow version
   2.0.0.dev0
   [airflow@ip-172-20-2-227 airflow]$
   ```
   
   I can't login through the Web UI, though.  It's asking me for username and password.
   
   When I started the webserver, it said:
   
   [2020-08-11 18:25:27,417] {manager.py:719} WARNING - No user yet created, use flask fab command to do it.
   
   I tried, but it didn't work. Help?
   
   ```
   
   [airflow@ip-172-20-2-227 airflow]$ flask fab create-user
   Role [Public]:
   Username: admin
   User first name: admin
   User last name: admin
   Email: admin@example.com
   Password:
   Repeat for confirmation:
   Usage: flask fab create-user [OPTIONS]
   
   Error: Could not locate a Flask application. You did not provide the "FLASK_APP" environment variable, and a "wsgi.py" or "app.py" module was not found in the current directory.
   [airflow@ip-172-20-2-227 airflow]$
   ```
