The intra-package references (module names starting with a dot) which
Flask uses were only added in Python 2.5. You're using 2.4.

You're using Python 2.4. Relative imports using the "dot" syntax were
introduced in 2.5. Upgrade to Python 2.5 or if that isn't possible
then run your Flask apps inside virtualenv.

Hi ,

from flask import Flask, Request, Response

You can try this?

I should have said "update to *at least* Python 2.5". Flask will of
course run on newer versions of Python 2.x, and it's better to have
the latest stable version (2.7).
