wingw-w64安装时 the file has been downloaded incorrectly!

参考：https://stackoverflow.com/questions/46455927/mingw-w64-installer-the-file-has-been-downloaded-incorrectly

windows10 开发一个GO项目时使用了cgo，依赖gcc，根据其他博客下载了mingw-w64-installer.exe在线安装，但下载文件时报了错

解决方法如下：

离线安装MinWG-w64

1. 访问链接https://sourceforge.net/projects/mingw-w64/files/，下载离线包并解压到你想要安装的目录
   

2. 选择版本后下载

点击下载后正常情况下应该是下载失败的（如果能正常下载应该就不会看见我了），这个时候复制浏览器链接，打开迅雷，新建下载就可以下载了（迅雷yyds）!

4. 解压到任意目录，配置环境变量

在环境变量后面要加/bin

5. 测试
打开cmd/powershell，执行gcc -v，若正常输出表示没有问题

总结

简单的来说就是sourceforge出问题了（或者是我们网络本身有问题），wingw-w64-installer.exe是在线安装，下载的还是sourceforge上面的东西，所以我们就不使用wingw-w64-installer.exe下载，手动下载解压就可以了；
其次，流程无法访问下载链接我们通过迅雷可以直接下载，如果是网络问题大家就可以使用其他kexueshangwang的方式解决。
