title: Python ImportError: No module named serial
body: <p>I have installed Python 2.7.5 on Ubuntu 12.4 on a DELL LATITUDE E4300 64 bit and ran:</p>
  
  <pre><code>sudo pip install pyserial
  </code></pre>
  
  <p>nevertheless when running:</p>
  
  <pre><code>sudo python main.py 
  </code></pre>
  
  <p>I receive the following error message:</p>
  
  <pre><code>Traceback (most recent call last):
    File "main.py", line 4, in &lt;module&gt;
      from mySerial import *
    File "/home/oscar/ath10k/tools/sanity_test/src/mySerial.py", line 6, in &lt;module&gt;
      import serial
  ImportError: No module named serial
  </code></pre>
  
  <p>I looked on other posts but none of them helped me to solve this problem. I don't know what else to do I also ran:</p>
  
  <pre><code>sudo -H pip install pyserial
  </code></pre>
  
  <p>and</p>
  
  <pre><code>sudo pip install pyserial --upgrade
  </code></pre>
  
  <p>Any help will be greatly appreciated.</p>
  
  <p>Kind regards.</p>
  
  <p>Oscar.</p>
