 pip install flask==0.9

Please guide me to install it correctly

If I may suggest, use Python 2.7. You will save yourself a world of pain! flask.pocoo.org/docs/python3. — Phil

Any reason you want to install specifically version 0.9? Why not pip install flask, which will install the latest 0.10.1 and its dependencies for Python 3.3.x? I tried it and it worked fine in virtualenv, while installing version 0.9 gave me the same error than you.

You can always got to pypi and download packages manually.

https://pypi.python.org/pypi/Flask

And then put the flask folder into the C:\Python33\lib\site-packages.

The problem you have is that the installer is not made for python3.

This makes me think that they did not prepare flask for python 3 which makes me guess that if you install flask under Python 3 you will have more problems. But you can try and be lucky.
