I am running the following code
from flask import Flask app = Flask(__name__) @app.route("/") def hello(): return "Hello World!" if __name__ == "__main__": app.run(host='0.0.0.0', port=80, debug=True)
and getting the following error
Traceback (most recent call last): File "test.py", line 1, in <module> from flask import Flask File "/home/pi/programs/flask.py", line 1, in <module> from flask import Flask ImportError: cannot import name Flask
I have tried installing flask through various methods , but still the problem persists
also, is there any alternative to flask???
apt-get install python3-flask
Edited to install the python3 version, since nobody should be using python2 now.
I ran into this error because I named the test file as flask.py and tried to run it! It creates namespace conflict with the real flask module!
Delete the local test file that you named flask.py and the respective flask.pyc. Give some other name! This will happen with other modules like
socket etc where you are likely to give the same name for the test file as the standard module :-)
