ImportError: No module named 'flask_cors'

[GijsGoudzwaard]

I have installed flask_cors like so: pip3 install -U flask-cors also tried pip install -U flask-cors

This is my code:

from flask import Flask
from flask_cors import CORS, cross_origin

app = Flask(__name__)
CORS(app)

Fixed it by doing this: pip install flask-cors --upgrade

[alanzulwas]

if upgrade cant do it, you can run python file, my file name called app.py, in virtual environent (venv) root@alanzulwas:/var/www/html/python# python3 app.py
