title: Virtualenv: Command not found
body: <p>I'm having problems trying to create my virtualenv folders' since my terminal says that virtualenv seems not to be installed. </p>
  
  <p>What did I do:</p>
  
  <pre><code>sudo pip install virtualenv
  </code></pre>
  
  <p>with this response:</p>

  ==&gt; Caveats
  Pip and setuptools have been installed. To update them
    pip install --upgrade pip setuptools
  
  You can install Python packages with
    pip install &lt;package&gt;
  
  They will install into the site-package directory
    /usr/local/lib/python2.7/site-packages
  
  See: https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/Homebrew-and-Python.md

  <p>I don't know how it says "Not installed" but when I run <code>python --version</code> I'm getting <code>Python 2.7.6</code> but if I go to usr/local/bin I can not see any python 2.7 or something what I see is a lot of python3.</p>
  
  <p>Any help? or suggestion to try to resolve this will be very aprecciated.</p>
  
  <p><strong>ANSWER:</strong></p>
  
  <p>I've resolved this issue uninstalling the virtualenv and installing again without any extra configuration or something.</p>
  
  <pre><code>sudo pip uninstall virtualenv
  sudo pip install virtualenv
  </code></pre>
