Upgrading pip You are using pip version 7.1.2 to version 8.1.2
<p>Hi I am trying to upgrade my pip version to 8.1.2 
this command does not work:
    pip install --upgrade pip  </p>

<p>And I also tried to get it directly from the github directory, like explained here <a href="https://github.com/pypa/pip/archive/8.1.1.zip" rel="nofollow">https://github.com/pypa/pip/archive/8.1.1.zip</a> but then i get the following error:</p>

<pre><code>Checking .pth file support in /Library/Python/2.7/site-packages/
error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

    [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/test-easy-install-21442.pth'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /Library/Python/2.7/site-packages/

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

  https://pythonhosted.org/setuptools/easy_install.html

Please make the appropriate changes for your system and try again.
