有我有开发人员正在开发的现有项目，我必须在他们的版本上做前端工作。我已经有红宝石在我的机器上运行良好，直到我尝试他们的版本。红宝石未能安装
看来mysql2不想安装。
以下是错误日志：

Make sure that `gem install mysql2 -v '0.3.12'` succeeds before bundling.
东西我曾尝试：
- 在这个具体问题 几乎每一个计算器的问题 - 手动安装MySQL（须藤宝石安装mysql - - -with-mysql-config =/usr/local/mysql/bin/mysql_config）
- 卸载ruby并重新安装
- 卸载rvm a次使用resintalling
- http://railsinstaller.org/
- mysql2 gem fails to compile with MySQL 5.6.12 on OS X with Homebrew
使用BREW安装也尝试和得到这个：
酿造安装mysql

在一个有点损失，以什么去做。我运行OSX。
你在使用什么操作系统？ – Shelvacu
