python爬虫实例--网易云音乐排行榜爬虫

进过各种努力, 终于找到了个大神写的博客,3.6版本的python

　　    python 代码下载地址:  https://github.com/imyxuan/Netease

　　　from Crypto.Cipher import AES

　　　　第一次错误: 提示没有安装Visual Studio 2015 Microsoft Build Tools 14.0     

　　　　　　下载地址:   https://www.microsoft.com/en-us/download/details.aspx?id=48130

　　　　运行修复工具修复完了后提示c++有异常 ,需要扩展修复.....然后工具-->选项-->扩展-->开始扩展.然后再修复一遍,提示c++修复成功!!

　　　　　　只能百度了: ,安装这个弄的:

　　　　　　　　1.设置Microsoft Visual Studio 14.0的环境变量 VCINSTALLDIR 变量值 C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC（默认安装位置，请根据自己的安装位置确定）如图：

　　　　　　3.在命令行(cmd)中执行 set CL=-FI"%VCINSTALLDIR%\INCLUDE\stdint.h"

　　　　 终于安装成功了, 然后信心满满的重启了我的PyCharm, 结果运行的时候还是找不到那个Crypto模块,这是已经过去好几个小时了没办法, 只能百度了..

　　　　python 的Crypto 安装目录: C:\Users\Administrator\AppData\Local\Programs\Python\Python36\Lib\site-packages
