我想知道我的错误是什么，或者是否有人对我应该解决的问题有指导？我不知道如何解决这个问题。用谷歌搜索了几个小时，但没有找到类似的东西。

【解决方案1】：

问题似乎是密码已更改，并且要设计发送电子邮件，但邮件程序存在问题

注册一个免费的 heroku 邮件插件，设置它，配置发送电子邮件的设备，然后重启你的 dyno

邮件问题

vendor/bundle/ruby/2.3.0/gems/mail-2.6.6/lib/mail/message.rb:2149:in `do_delivery'
vendor/bundle/ruby/2.3.0/gems/mail-2.6.6/lib/mail/message.rb:237:in `block in deliver'
vendor/bundle/ruby/2.3.0/gems/actionmailer-5.1.4/lib/action_mailer/base.rb:558:in `block in deliver_mail'

设计触发器

vendor/bundle/ruby/2.3.0/gems/devise-4.3.0/lib/devise/models/recoverable.rb:134:in `send_reset_password_instructions'
vendor/bundle/ruby/2.3.0/gems/devise-4.3.0/app/controllers/devise/passwords_controller.rb:13:in `create'

【讨论】：

我已经将以下代码添加到我的项目中，并且已经让 Sendgrid 工作了一段时间：Rails.application.initialize! ActionMailer::Base.smtp_settings = { :address => 'smtp.sendgrid.net', :port => '587', :authentication => :plain, :user_name => ENV['SENDGRID_USERNAME'], :password => ENV['SENDGRID_PASSWORD'], :domain => 'heroku.com', :enable_starttls_auto => true }
尝试从模型的设计设置中删除 :recoverable 和 :confirmable

【解决方案2】：

我最终只是重置了整个数据库来修复它（我仍在开发中，所以这没什么大不了的）。如果您在生产中遇到此问题，我建议您使用rails console 手动重置您的用户密码。这应该有助于解决问题。由于我的 ISP 阻止了 5000 端口以便能够运行 heroku run rails console，我在连接到 Heroku 时也遇到了问题。
