python库的安装步骤总共分为3步，具体的安装方法如下：

1、首先下载“python”安装下载库；如果没有配置python的环境变量，那么先要在“环境变量PATH”一项里加入“python安装目录”选项；

2、解压后，在命令行中执行“cd”到“distribute”文件夹目录，输入pytho”执行，等待安装完成；

3、在环境变量中，加入安装目录“cripts”文件夹，解压下载好的第三方库，在命令行执行到解压后目录，最后点击界面“确认”按钮即可。

总结：

【方法一】: 通过setuptools来安装python模块
首先下载
NOTE: 最好下载个setuptools，本人是15.2版本，里面包含了ez_setup
运行 python ez_setup.py
D:\work\installation\setuptools-15.2\setuptools-15.2>python ez_setup.py > 1.txt
Extracting in c:\users\admini~1\appdata\local\temp\tmpbxikxf
Now working in c:\users\admini~1\appdata\local\temp\tmpbxikxf\setuptools-15.2
