Answer 1

This is an environment error -- whatever IDE you're using doesn't have the PYTHONPATH set properly. You can test this out by creating a small test file: test.py, with the following contents:

from os import environ
print environ.get('PYTHONPATH')

If the PYTHONPATH doesn't contain the directory that holds your Flask-Login package, then that's the issue.

Answer 2

Initially I installed flask_login on virtual environment. I found out that its trying to find on the machine. So I installed it globally as;

mycomp# pip install -U flask_login

That solved the problem.
