我在我的 MAC (Mavericks 10.9.1) 上安装了 RVM 和 rails，并尝试运行 rake db:create。但是我经常收到这个错误：

另外，如何正确安装 MySQL 服务器以便设置默认密码？它要求我在 Windows 机器上输入密码，但在我安装 MySQL5 + server 时它没有。谢谢！

【问题讨论】：

你是怎么安装mysql的？也许是 MySQL 安装程序或自制软件？
自制。然后我从安装程序安装。依然没有。我都重新安装了，有什么建议吗？

尝试通过自制软件重新安装mysql。并重新安装mysql gem
gem install mysql -- --with-mysql-config path/to/mysql_config
