First make sure you've installed Python 3 and are using it inside a virtual environment. Now, execute the workon command to see a list of virtual environments in your machine. This should list py3-flask in a line. to ensure that you are indeed inside a Python 3 environment.
To run the app outside of the VS Code debugger, use the following steps from a terminal: Set an environment variable for FLASK_APP . On Linux and macOS, use export set FLASK_APP=webapp ; on Windows use set FLASK_APP=webapp . Navigate into the hello_app folder, then launch the program using python -m flask run .
To check if you have actually installed flask, try this command: pip freeze then check if it is actually listed. Normal procedure to start a flask app would be: - create a virtual environment. Make sure you are using python 3. check by using this command.
Flask 0.10 has no flask command, it was added in 0.11. If pi.py has the smarts to run your app, such as if it's using Flask-Script, the command you're looking for is:
$ python pi.py You can install Flask-CLI to get the flask command in 0.10 if you can't upgrade to 0.11.
