输入> $ 导轨 G 脚手架 用户名：字符串 电子邮件：字符串

这是我
的配置/初始值设定项/setup_mail.rb 的内容
我正在使用Heroku和Sendgrid并安装了插件。
我是否需要先安装"邮件"gem，文档没有提到它？
ActionMailer::Base.smtp_settings = {
:address => "smtp.sendgrid.net",
:port => "25",
:authentication => :plain
:user_name => "apxxxxx@heroku.com",
:password => "9XXXXXXXXX",
:domain => "www.myapp.com",
}
我知道现在的问题是什么 - 用户名和密码条目后没有逗号！
