I am trying to set up some sample code with flask+python on my machine, I am following the website as below

http://blog.miguelgrinberg.com/post/flask-pagedown-markdown-editor-extension-for-flask-wtf

However I have a problem as below.

from flask.ext.pagedown import PageDown


Traceback (most recent call last):
  File "/Users/iMacBin/Documents/projects/flask/flasky/manage.py", line 3, in <module>
    from app import create_app, db
  File "/Users/iMacBin/Documents/projects/flask/flasky/app/__init__.py", line 7, in <module>
    from flask.ext.pagedown import PageDown
  File "/Library/Python/2.7/site-packages/Flask-0.10.1-py2.7.egg/flask/exthook.py", line 87, in load_module
    raise ImportError('No module named %s' % fullname)
ImportError: No module named flask.ext.pagedown

I did install flask-pagedown, markdown and bleach using pip on my machine. 

(venv) $ pip install flask-pagedown markdown bleach

I did search online and noticed that flask.ext might be stale, so I also tried 

from flask_pagedown import PageDown

but it has the same issue, 'No module named flask_pagedown'

FYI, my python version is 2.7.6. The IDE I am using is PyCharm.

Could anybody advise anything else I can check?
