from Crypto.Cipher import AES
在python中要使用到crypto相關的庫，但是網上的解決方法能用的沒有幾個。
首先我告訴大家為什么不能安裝，其次告訴一種真正的方法。
pycrypto，pycrytodome和crypto是一個東西，crypto在python上面的名字是pycrypto它是一個第三方庫，但是已經停止更新三年了，所以不建議安裝這個庫；
windows下python3.6安裝也不會成功！
這個時候pycryptodome就來了，它是pycrypto的延伸版本，用法和pycrypto 是一模一樣的；
所以，我現在告訴一種真的解決方法：直接安裝：
pip install pycryptodome
這里有一個注意點
一定要安裝Microsoft Visual C++ Build Tools
如果不安裝，直接會報錯，下圖是報錯中的部份截圖

（親測，目前不用改文件夾名字了） 但是，在使用的時候導包是有問題的，這個時候只要修改一個文件夾的名稱就可以完美解決這個問題
C:\Users\Administrator\AppData\Local\Programs\Python\Python36\Lib\site-packages
找到這個路徑，下面有一個文件夾叫做crypto,將c改成C，對就是改成大寫就ok了！！！
