很难根据提供的信息确切地知道您的安装所处的状态。
/usr/local/bin是Apple提供的默认安装位置，
/usr/bin/easy_install因此很可能是通过某种方式调用了它，而不是
easy_install通过运行
shsetuptools...脚本来安装该位置。无需在
--install-dirsetuptools中使用参数，也无需
PYTHONPATH指向框架site-packages目录。那会自动发生。而且，您不应修改
PATH变量两次，而只需使用第一个PATH并导出即可。
从python.org安装程序中新安装的Python 2.6.5开始，并执行新的终端会话，以下是整个过程：
