mysql - 无法创建新应用程序 "rails new todo -d mysql"

Question

我想通过执行以下命令来创建一个新的 Rails 应用程序。

$rails new todo -d mysql

但在此过程中我收到了错误消息。

我使用的是 OS X Yosemite(10.10.5) 和 MySQL(5.7.9)

Ruby版本也是这样。

请给我解决此错误的任何想法。

$ruby -v
ruby 2.1.7p400 (2015-08-18 revision 51632) [x86_64-darwin14.0]


$ rails new todo -d mysql
