from Crypto.Cipher import AES
在python中要使用到crypto相关的库，但是网上的解决方法能用的没有几个。
首先我告诉大家为什么不能安装，其次告诉一种真正的方法。
pycrypto，pycrytodome和crypto是一个东西，crypto在python上面的名字是pycrypto它是一个第三方库，但是已经停止更新三年了，所以不建议安装这个库；
windows下python3.6安装也不会成功！
这个时候pycryptodome就来了，它是pycrypto的延伸版本，用法和pycrypto 是一模一样的；
所以，我现在告诉一种真的解决方法：直接安装：
pip install pycryptodome
这里有一个注意点
一定要安装Microsoft Visual C++ Build Tools
如果不安装，直接会报错，下图是报错中的部份截图

（亲测，目前不用改文件夹名字了） 但是，在使用的时候导包是有问题的，这个时候只要修改一个文件夹的名称就可以完美解决这个问题
C:\Users\Administrator\AppData\Local\Programs\Python\Python36\Lib\site-packages
找到这个路径，下面有一个文件夹叫做crypto,将c改成C，对就是改成大写就ok了！！！
