ImportError: No module named flask.ext.login

Question

I have a problem with flask_login module.

i have installed flask_login module successfully. Also from the command prompt i can run this script easily with no error:

Python 2.7 (r27:82525, Jul  4 2010, 07:43:08) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from flask.ext.login import LoginManager

But when I am running this script:

from flask import Flask
from flask.ext.login import LoginManager
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World! Welcome"

if __name__ == "__main__":
    app.run()

i am getting the error :

ImportError: No module named flask.ext.login

What is the mistake i am doing. I am very new to this flask. Thanks in advance.

Answer 1

If following does not work:

from flask.ext.login import LoginManager

try the following:

from flask_login import LoginManager

This is the new convention.

To find the flask-login version, you can run the following command in terminal. Just change the name to know the version of other packages.

pip show flask-login

Answer 2

Install pip and then use the following command:

C:\Python27\scripts>pip install Flask-Login
