【问题描述】：

一切都很顺利......

gem 'mail' 已安装

输入> $ rails g 脚手架用户名：字符串电子邮件：字符串

输入 > $ rake db:migrate（我可以在 http://localhost:3000/users/new 上看到它）然后...

输入 > $ rails g mailer user_mailer

在这个命令中我得到了这个巨大的错误——它是什么以及如何解决它？

【问题讨论】：

可以发config/initializers/setup_mail.rb的内容吗？
您的应用程序中在哪里引用了DevelopmentMailInterceptor？
@dmarkow 已按要求发布 setup_mail.rb....
这是您的setup_mail.rb 文件的全部内容吗？错误信息引用了该文件的第 14 行，但您发布的内容只有大约 8 行。

【解决方案1】：

这是我的 config/initializers/setup_mail.rb 的内容

我正在使用 Heroku 和 Sendgrid，并且已经安装了插件。

我需要先安装“邮件”gem，文档没有提到吗？？

ActionMailer::Base.smtp_settings = {
:address        => "smtp.sendgrid.net",
:port           => "25",
:authentication => :plain
:user_name      => "apxxxxx@heroku.com",
:password       => "9XXXXXXXXX",
:domain         => "www.myapp.com",
}

我知道现在是什么问题 - 用户名和密码输入后没有逗号！

【讨论】：

@我是否应该将缺少的逗号放入答案中以便更清楚？！
