title: pyserial, ImportError: No module named serial
body: <p>I know this question have been asked several times, but none of the solutions I saw solved my problem. </p>
  
  <p>I have been trying to use the serial library from Sublime Text 2 in my mac.</p>
  
  <pre><code>import serial
  </code></pre>
  
  <p>Everytime I call this library, I get this message: </p>
  
  <pre><code>  Traceback (most recent call last):
      File "/Users/andreapatri/Desktop/test.py", line 1, in &lt;module&gt;
        import serial
    ImportError: No module named serial
    [Finished in 0.0s with exit code 1] 
  </code></pre>
  
  <p>I already installed python 3</p>
  
  <pre><code>brew install python3
  </code></pre>
  
  <p>and pyserial</p>
  
  <pre><code>sudo pip install pyserial
  </code></pre>
