title: I get an error in python3 when importing mechanize
body: <p>I get an error in python3 when importing mechanize.</p>
  
  <p>I've just installed mechanize into my virtualenv where python3 is installed.</p>
  
  <pre><code>$ which python3
  /Users/myname/.virtualenvs/python3/bin/python3
  
  $ pip freeze
  mechanize==0.2.5
  </code></pre>
  
  <p>But, when I try to import mechanize in my python code, I get this error.</p>
  
  <pre><code>import mechanize
  
  ---------------------------------------------------------------------------
  ImportError                               Traceback (most recent call last)
  &lt;ipython-input-1-6b82e40e2c8e&gt; in &lt;module&gt;()
  ----&gt; 1 import mechanize
  
  /Users/myname/.virtualenvs/python3/lib/python3.3/site-packages/mechanize/__init__.py in &lt;module&gt;()
      117 import sys
      118 
  --&gt; 119 from _version import __version__
      120 
      121 # high-level stateful browser-style interface
  
  ImportError: No module named '_version'
  </code></pre>
  
  <p>Does anyone know how to fix this problem?</p>
  
  <p>I'm new to python and I've been studying how to program in python these days.</p>
  
  <p>Thanks for your help in advance!</p>
