  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。

Answer 1

你的Python安装有些搞砸了。

首先，运行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。您将从不需要sudo才能使用virtualenv。

其次，Mountain Lion默认不包含/Library/Python/2.7/site-packages/virtualenv.py。有什么东西安装在那里，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。

看来即使您正在创建virtualenv，它也会尝试将软件包安装到/Library/Python/2.7/site-packages/中，这是不可能的。可能是您使用sudo easy_install安装virtualenv，还是手动将一些软件包放在/Library/Python/2.7/site-packages/中？

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，将安装virtualenv和无需任何思考就可以为您提供：https://github.com/brainsik/virtualenv-burrito

Answer 2

哎呀，忘了写这个问题的答案。

我的Python目录有一大堆权限和包相关的问题;最后完成了卸载，然后从Python.org安装了最新版本。

此后一直很好。

无法在OSX上运行virtualenv？

sudo virtualenv foo

virtualenv foo
