IOError: [Errno 13] when installing virtualwrapper
<p>After successfully installling virtualenv in terminal with 'pip install virtualenv', I tried installing virtualwrapper  with 'pip install virtualenvwrapper' and something seems to have gone wrong with some code presenting in red instead of the usual white. There was about 20-30 lines of code in essence it said the following:</p>

<p>Installing collected packages: virtualenv-clone, pbr, stevedore, virtualenvwrapper</p>

<p>Exception:</p>

<p>Traceback (most recent call last):</p>

<p>Then there is a list of file paths shown, followed by..</p>

<blockquote>
  <p>IOError: [Errno 13] Permission denied:
  '/usr/local/lib/python2.7/dist-packages/clonevirtualenv.py'</p>
</blockquote>

<p>Does anyone know what could have gone wrong and how I can fix it?</p>

<p>Thanks</p>

<p>when it's about permission problem you have try with sudo(super user).</p>

<p>if Linux,</p>

<p><code>$ sudo pip install virtualenvwrapper</code></p>

<p>if Windows,</p>

<p>open cmd with administration privilege and then,</p>

<p><code>pip install virtualenvwrapper</code></p>

python virtualenvwrapper errno ioerror
