body: <p>I'm having trouble installing mysql-python. Created a new virtualenv and when installing mysql-python... here's the error message:</p>
  
  <pre><code>(env)$ pip install mysql-python
  Collecting mysql-python

  <p>Using homebrew, I have installed:</p>
  
  <ul>
  <li>libressl</li>
  <li>openssl</li>
  <li>openssl@1.1</li>
  <li>mysql</li>
  </ul>
  
  <p>Already tried to <code>brew link</code> but brew refuses to do so.</p>
  
  <p>The OS is MacOS Sierra.</p>
  
  <p>Can anyone help? Thanks!</p>
