title: ImportError: No module named flask.ext.mysql
body: <p>Hi I am trying to run a python file that has :</p>
  
  <pre><code>from flask import Flask, render_template, json, request
  from flask.ext.mysql import MySQL
  from werkzeug import generate_password_hash, check_password_hash
  </code></pre>
  
  <p>I started in windows, I got the same error :</p>
  
  <pre><code>ImportError: No module named flask.ext.mysql
  </code></pre>
  
  <p>Someone told me don't develop python in windows, it's lot of headache, so I started the same project in Ubuntu, but I got the same problem :</p>
  
  <pre><code>vagrant@precise32:/vagrant/FlaskMysql/FlaskApp$ python app.py
  Traceback (most recent call last):
  File "app.py", line 2, in &lt;module&gt;
  from flask.ext.mysql import MySQL
  File "/usr/local/lib/python2.7/dist-packages/flask/exthook.py", line 87, in    load_module
  raise ImportError('No module named %s' % fullname)
  ImportError: No module named flask.ext.mysql
  </code></pre>
  
  <p>Please your help is appreciated.</p>
