I was trying to install cvxopt to my OSX system. But It didn't work. I just followed the instruction of the standard installation on: http://cvxopt.org/install/#standard-installation. The response from the terminal is as follows:

running install 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-527.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.

Anyone could help me? Thank you very much~

You are trying to install the package to a system owned folder location. You can overcome this by running sudo python setup.py installm but you will end up with a mess of installed libraries. Rather create a virtual environment in a location that your user owns. This way you keep your main python install clean and can chop and change versions as you need.
