flask.cli.NoAppException: The file/path provided (new_app.py) does not appear to exist
I keep getting this error flask.cli.NoAppException: The file/path provided (new_app.py) does not appear to exist. Please verify the path is correct. If app is not on PYTHONPATH, ensure the extension is .py it goes away after I restart the Flask server. I am running flask run in the correct directory where my app is. This just started happening after working for 2 weeks. I've read that it could be due to an import error, but I am not finding any modules that are not installed on my virutalenv. from flask import Flask app = Flask(__name__) app.debug=True
Most likely you haven't set the FLASK_APP environment variable. To run the application you can either use the flask command or python’s -m switch with Flask. Before you can do that you need to tell your terminal the application to work with by exporting the FLASK_APP environment variable: $ export FLASK_APP=hello.py $ flask run * Running on http://127.0.0.1:5000/ If you are on Windows you need to use set instead of export. Alternatively you can use python -m flask: $ export FLASK_APP=hello.py $ python -m flask run * Running on http://127.0.0.1:5000/
