1、首先去https://pypi.python.org/pypi/setuptools下载到最新的setuptools压缩包，比如：setuptools-11.3.zip。
2、然后解压到某一个文件目录下。
3、然后用如下命令做安装。
python setup.py install。
4、安装完成后，在C:\Python27\Lib\site-packages的目录下出现了，类似于：setuptools-11.3-py2.7.egg文件，表示安装成功。
5、然后继续安装pip，看如下的安装命令的安装过程就可以了。
看到最后一行是：
Finished processing dependencies for pip
表示安装成功了。
c:\Python27\Scripts>easy_install.exe pip
