当在终端执行Python脚本时，出现以下报错，说明你的Python缺少biplist库！

AmpawdeiMac:~ Ampaw$ /Users/Ampaw/Desktop/test.py
Traceback (most recent call last):
File "/Users/Ampaw/Desktop/test.py", line 3, in <module>
    from biplist import *
ImportError: No module named biplist
AmpawdeiMac:~ Ampaw$

  注意：Mac自带的Python是没有biplist库的，如果你的Python脚本需要添加biplist库才可以运行，应先安装biplist库。

安装方式

   1. 使用setuptools工具安装，下载地址：http://pypi.python.org/pypi/setuptools 可以找到正确的版本进行下载
   2. 直接安装biplist库，下载地址：https://pypi.python.org/pypi/biplist

具体操作

   第一种方式，可以自行 百度 来安装工具，这里主要介绍第二种方式直接下载安装biplist库。

1. 下载biplist库压缩文件，并解压缩
2. 终端执行命令，切换到biplist库文件目录

cd ~/biplist库文件

3. 终端执行命令，安装biplist库

sudo python setup.py install

4. 执行命令后，显示以下信息时，表示biplist库，安装成功！
