  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-1712.write-test'

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:

  http://peak.telecommunity.com/EasyInstall.html

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

我正在运行Python 2.7.3并且没有安装任何软件包,除了默认情况下,OSX Mountain Lion上的pip和virtualenv.

你的Python安装有些搞砸了.

首先,跑步sudo virtualenv foo没有任何意义.virtualenv的重点是,您不需要root访问权来安装包.你永远不需要sudo来使用virtualenv.

其次,/Library/Python/2.7/site-packages/virtualenv.py默认情况下不包括Mountain Lion.有东西安装在那里,所以当你说"没有安装任何软件包,除了默认情况下",你就错了.根据您的安装方式,可能安装错误.

看起来即使你正在创建virtualenv,它也试图安装包/Library/Python/2.7/site-packages/,这是不可能的.可能是你曾经sudo easy_install安装virtualenv,或手动放入一些包/Library/Python/2.7/site-packages/？

我建议你不要安装和卸载你安装的任何东西,让你的系统恢复到标准的Mac OS X设置,然后使用virtualenv-burrito,这是一个一步的命令,将为你安装virtualenv和pip无需考虑:https://github.com/brainsik/virtualenv-burrito
