Ruby on rails 添加Linkedin身份验证时发生迁移错误

我正在尝试在我的rails应用程序中使用Linkedin的api进行身份验证。我对rails非常陌生，所以我遵循了这个指南

我尝试运行rake db:migrate，但出现了这个错误。下面是完整的跟踪。我还添加了environment.rb文件，因为我认为这就是问题所在，但我不确定。另外，如果有人对如何在rails中使用linkedin API有更好的指导，请分享！谢谢你的帮助

environment.rb文件

require File.expand_path('../application', __FILE__)

config.app_domain = 'somedoamin.com'

config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.default_url_options = { host: config.app_domain }
config.action_mailer.smtp_settings = {
  address: 'smtp.gmail.com',

  user_name: 'someuser',

 }

Rails.application.initialize!

您的environment.rb确实是问题所在。其中的所有配置代码：

config.app_domain = 'somedoamin.com'

config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.default_url_options = { host: config.app_domain }
config.action_mailer.smtp_settings = {
  address: 'smtp.gmail.com', 
  port: '587',
  enable_starttls_auto: true,
  user_name: 'someuser',
  password: 'somepass',
  authentication: :plain,
  domain: 'somedomain.com'
 }

在错误的地方。它应该在application.rb或config/environments/development.rb中，如果它是特定于开发的。

o，我认为这是可行的，但我现在遇到了这个错误。抱歉，不确定评论中的格式如何。。无效的路由名称，已在使用：'new_user_session'这里是我的路由文件'Rails.application.routes.draw do design_for:users root'pageshome'get about=>pagesabout创建关于路径designe_for:users，：controllers=>{omniauth_callbacks:'omniauth_callbacks'}match'/users/:id/finish_signup'=>'usersfinish_signup'，via:[：get，：patch]，：as=>：完成注册是的，你应该开始一个新问题。
