body: <p>After experiencing <a href="https://github.com/mxcl/homebrew/issues/17312">this</a> brew issue with sqlite3, I did</p>
  
  <pre><code>brew rm sqlite python python3
  </code></pre>
  
  <p>then </p>
  
  <pre><code>brew install python python3
  </code></pre>
  
  <p>This installed python2.7.5 as the default interpreter and as brew installs pip along with python, I thought I would be able to</p>
  
  <pre><code>pip install virtualenv
  </code></pre>

  <pre><code>-bash: /usr/local/share/python/pip: /usr/local/Cellar/python/2.7.3/bin/python: bad interpreter: No such file or directory
  </code></pre>
  
  <p>How can I get around/fix this? Should I be creating a symlink between </p>
  
  <pre><code>/usr/local/share/python/pip --&gt; /usr/local/Cellar/python/2.7.5/bin/pip-2.7
  </code></pre>
