此错误。

更新：

我试图再次安装MySQL，越来越：

Successfully installed mysql-2.7.3-x86-mswin32 1 gem installed Installing ri documentation for mysql-2.7.3-x86-mswin32... Installing RDoc documentation for mysql-2.7.3-x86-mswin32... ERROR: While generating documentation for mysql-2.7.3-x86-mswin32 ... MESSAGE:

在我看来，你是错过了MySQL的宝石。

尝试

gem install mysql
