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：

Don't know how to set rpath on your system, if MySQL libraries are not in path mysql2 may not load

Setting libpath to /usr/local/Cellar/mysql/5.7.16/lib

creating Makefile

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
