Warning message while running Flask

Question

While I am running Flask code from my command line, a warning is appearing:

Serving Flask app \"hello_flask\" (lazy loading)
* Environment: production
  WARN         


        

Answer 1

If you encounter NoAppException and you see lazy loading the following seemed to fix the issue:

cd 
export FLASK_APP=.
export FLASK_ENV=development
export FLASK_DEBUG=1
