所以我一直在修改 Devise 视图，当我查看 Forgot Password 视图，然后点击注册的电子邮件地址并单击“向我发送重置密码说明”时，令我惊讶的是，我收到了这个：

这是服务器日志：

我做错了什么，我该如何解决？

【解决方案1】：

安装devise后告诉你至少需要复制以下内容

config.action_mailer.default_url_options = { :host => 'localhost:3000' }

致config/environments/development.rb

为邮寄者设计需要。

我正在根据控制器规范测试请求，并且恰好需要该行。谢谢

【解决方案2】：

Devise 需要一些额外的配置才能通过电子邮件重置密码。除了用于实际发送重置电子邮件的电子邮件帐户和密码之外，它还需要一个主机来发送电子邮件。
