I'm trying to get a hello world flask app running with Python 3.9.7.
Folder structure:
py-flask/
app.py
README.md
Content of app.py:
from flask import flask
app = flask(__name__)
@app.route("/")
def index():
return "Hello Wolford"
@app.route("/greeting/")
def greeting():
return "Nice to see you"
When I am in the py-flask directory, and I try running the app, I get:
Error: While importing 'app', an ImportError was raised.
I've tried python3 -m flask run and flask run neither works.
Any thoughts on what I could be doing wrong?
pip list if its useful:
Package Version
------------- -------
cachelib 0.4.1
click 8.0.3
Flask 2.0.2
Flask-Session 0.4.0
itsdangerous 2.0.1
Jinja2 3.0.2
MarkupSafe 2.0.1
pip 21.2.3
setuptools 57.4.0
Werkzeug 2.0.2
If your typing here is correct, the error is that the importet module is misspelled (Flask must be uppecase). Here the correct way:
from flask import Flask
app = Flask(__name__)
@app.route("/")
def index():
return "Hello Wolford"
@app.route("/greeting/")
def greeting():
return "Nice to see you"
