[FIXED] how to solved no module named 'flask_cors'

Issue

from flask import Flask
from flask_cors import CORS
app = Flask(__name__)
CORS(app)
@app.route('/')
def home():
    return 'Hello, World!'
if __name__ == '__main__':
    app.run(debug=True)

It's currently 3.10.0 version and I've tried sys.path.append, pip install -u flask_cors pip3 install flask_cors, etc. It doesn't work for people who have the same problem as me.

If you move the cursor to flask_cors, the message No module named 'flask_cors' appears.

Also, when I run python app.py, I get ModuleNotFoundError: No module named 'flask_cors'.

Any help would be appreciated.

Solution

I had the same issue some months ago, can you check that all packages are correctly installed with pip freeze.

import sys
import os
from flask import Flask, request, jsonify, redirect

try:
    from flask_cors import CORS, cross_origin  # The typical way to import flask-cors
except ImportError:
    # Path hack allows examples to be run without installation.
    import os
    parentdir = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    os.sys.path.insert(0, parentdir)
    from flask_cors import CORS, cross_origin


app = Flask(__name__)
CORS(app)

My requirments for this code :

Flask==1.1.1
Flask-Cors==3.0.8
Flask-Migrate==2.5.2
Flask-Script==2.0.6
Flask-SQLAlchemy==2.4.0
psycopg2-binary==2.8.3
