ImportError：没有名为 pip 的模块

Question

新手上路，请多包涵

操作系统：Mac OS X 10.7.5 Python 版本：2.7.5

我已经从 https://pypi.python.org/pypi/setuptools 安装了带有 ez_setup.py 的 setuptools 1.0 然后我从 https://pypi.python.org/pypi/pip/1.4.1 下载了 pip.1.4.1 pkg .

在 iTerm 中运行 (sudo) python setup.py install 表明

然后我输入 pip install ，错误信息显示如下

以前遇到过同样问题的任何人都可以给我一些解决方法吗？
