这是一件更容易做的事情，对您来说可能会更好。打开一个终端（“应用程序”->“实用程序”->“终端”），并将其作为外壳脚本运行。您也可以运行单个命令。
#!/bin/sh
cd ~
# Downloads python setuptools for 2.6
curl -o setuptools-0.6c11-py2.6.egg http://pypi.python.org/packages/2.6/s/setuptools/setuptools-0.6c11-py2.6.egg#md5=bfa92100bd772d5a213eedd356d64086
# installs it, will probably prompt you for password
sudo sh setuptools-0.6c11-py2.6.egg
# clean up and delete egg
rm setuptools-0.6c11-py2.6.egg
我只是在自己的Mac机器上执行此操作，安装顺利完成。您是否打开了终端来执行此操作？
我将setuptools下载到我的Downloads文件夹中，然后打开一个终端，并执行以下操作：
> cd ~/Downloads
> sudo sh setuptools-0.6c11-py2.6.egg
