Answer 1

Different shell programs have different ways to set the environment variable in it. So that Flask can discover you application correctly.

• Unix Bash/Zsh (Linux, Mac, etc.):

  $ export FLASK_APP=hello
  $ flask run
  

• Windows CMD:

  > set FLASK_APP=hello
  > flask run
  

• Windows PowerShell:

  > $env:FLASK_APP = "hello"
  > flask run
  

You can find more infomation in the Flask docs.
