Running Flask app in VS Code - Error: Could not import App

I get this error running a Flask app out of Visual Studio Code (VS Code):

*Serving Flask APP "myWebSite.py"
*Environment: production WARNING:
Do not use the development server in a production environment. Use a production WSGI server instead.

  • Debug mode:off Useage: flask run [OPTIONS]

Error: Could not import "myWebSite"

When I run it out of another PC with Visual Studio Code it runs fine. What could it be?

Solution

  • You will want to check you have all the requirements installed using pip.

    Then the trick is you need to select the correct debugger in Visual Studio Code:

    Python: Current File (Integrated Terminal)

    If you have another selected such as Python: Flask it causes the error.

    Another way is right click on the contents of myWebSite.py and Python Run in Terminal.
