错误：安装mysql2时出错：错误：无法构建gem原生扩展.在Mac 10.12上

I tried every solution similar to the question:

最近,我从ubuntu转移到Mac,我试图在Sierra上安装mysql gem,之后我安装了Ruby,Rails,MysqL,

我也输入brew install MysqL,它可以下载MysqL而不是gem,所以我的问题并不相似.

我输入了这个MysqL –version

我使用EditLine包装器为osx10.12(x86_64)获得了MysqL Ver 14.14 distrib 5.7.16

我试图安装MysqL2 gem for rails来构建一个新的应用程序

我输入了这个sudo gem install MysqL2并得到了这个错误：

解决方法:

我的问题很好的答案,感谢@Holger只是在githup ld: library not found for -lssl` after Mac OS Sierra upgrade上引用这个问题
