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

我通过brew&rbenv安装了rails.版本如下:
Ruby版本: ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin16]
Rails版本: Rails 4.2.6
MySql版本: mysql-5.7.16
拉起终端实例并运行:
brew doctor
构建mysql gem的一个或多个依赖项可能已过时.
你必须运行:
brew update
您最近也可能升级到OS X的Sierra版本.确保您的XCode命令行工具是最新的.跑:
xcode-select --install
通过运行以下命令确保您接受新版XCode的许可:
sudo xcodebuild -license
