Day 61 L464 - Installing Flask-WTF

main.py

from flask import Flask, render_template

app = Flask(__name__)


@app.route("/")
def home():
    return render_template('index.html')


@app.route("/login")
def login():
    return render_template("login.html")


if __name__ == '__main__':
    app.run(debug=True)

I still have this error message after upgrading the framworks.

Add Werkzeug==2.2.2 to your requirements.txt

I still have error on "address already in use and start with a new server port"

For people who see this part in December 2022 and receive error : ImportError: cannot import name 'Markup' from 'jinja2', put below codes inside of requirement.txt. Good luck!.

click==8.0.4 Flask==2.0.3 itsdangerous==2.1.2 Jinja2==3.1.1 MarkupSafe==2.1.1 Werkzeug==2.0.3

Thanks man this works.
