Unable to import flask_login
First, make sure that flask_login was installed successfully by running "pip list" in your project directory terminal, If it isn't there then you should install it again 
Second, if it is there so make sure of any typo mistakes, also you can share that piece of code to check it.
I am following the book explore flask on explore flask site, I am getting this error, I just installed flask-login and import this as following
pip install flask-login
from flask_login import login_required
I expect to save this normally without any errors, but VS CODE terminal show this error
"Unable to import 'flask_login'
