在用Python3+版本中遇到下载安装pycrypto等或其他第三方插件报错的问题
（试过很多百度上的方法，什么卸载重装，什么下载whl文件，都没用，以下是总结的解决方案）
1.首先是常见error，缺少C++组件（如不是此问题，请跳过看一下一个问题）：
报错内容：Microsoft Visual C++ 14.0 is required.
报错原因：组件缺失
解决办法：根据python版本下载安装不同的组件就行了，如果你用的也是 Python3.5 以上高版本，
恭喜你直接使用我这里的下载链接下载Microsoft Visual C++ 14.0就行了

2.组件inttypes.h报错，错误内容：

错误原因：默认文件语法错误
解决办法（以上问题已解决的前提，安装好了Microsoft Visual Studio 14.0）：
1. 找到你Microsoft Visual Studio 14.0的安装路径，并切到指定地址
我的地址是：C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include
2. 复制stdint.h文件到下面截图指定路径
例如我的地址是：C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt
3. 然后修改这个报错地址的文件，#include <stdint.h> 改为 #include "stdint.h"
注意是英文的双引号！！
如下图：
最后就是再安装就成功了，上图：
