title: Could not import 'webapp'
body: <p>I am typing the command :
  set FLASK_APP =file_name.py and get no feedback(expected as far as I know), but than when I try to launch:
  flask db init<br />
  I get error:<br />
  Error Could not import 'webapp'.
  I tried a lot of different ways to overcome this one, but nothing helped.<br />
  EDIT:<br />
  I created a file called 'webapp.py', and now I get the error:
  Failed to find Flask application or factory in module 'app'. Use 'FLASK_APP=app:name' to specify one.
