title: Getting "ImportError: No Module named yaml" error
body: <p>Computer: MacBook Pro mid 2012, running El Capitan 10.11.4</p>
  
  <p>Python version 2.7.10</p>
  
  <p>I've been trying to install ansible from source, and I've run these two commands (following the steps on ansibles documentation):</p>
  
  <pre><code>git clone git://github.com/ansible/ansible.git --recursive
  cd ./ansible
  </code></pre>
  
  <p>and then ran this</p>
  
  <pre><code>source ./hacking/env-setup
  </code></pre>
  
  <p>I've also already installed these packages</p>
  
  <pre><code>sudo pip install paramiko PyYAML Jinja2 httplib2 six
  </code></pre>
  
  <p>However, if I try and run ansible by typing it in the terminal, I get the following error.</p>
  
  <pre><code>Traceback (most recent call last):
  File "/Users/[myusr]/rock/ansible/bin/ansible", line 81, in &lt;module&gt;
  from ansible.cli.adhoc import AdHocCLI as mycli
  File "/Users/[myusr]/rock/ansible/lib/ansible/cli/__init__.py", line 27, in &lt;module&gt;
  import yaml
  ImportError: No module named yaml
  </code></pre>
  
  <p>What should be done here?</p>
