Using the Flask CLI
Who knew that flask had a cli? Previously I used to just use manage.py just like Django does it to “do stuff”. The CLI is great, but again it follows the theme of kind of wanting you to install your flask app. (I really should do this). So in order to get your app to work you must point the FLASK_APP variable to the actual python file (not your app module). This is true even if you have a true python module. For instance.
export FLASK_APP = blog/blog.py flask run
export FLASK_APP = blog flask run
blog/ __init__.py blog.py
