【问题描述】：
错误信息： "没有路线匹配 [GET] "/auth/google_oauth2"
查看页面链接：
<%= link_to "Log In with Google", "/auth/google_oauth2" %>
相关宝石：
gem 'omniauth'
gem 'dotenv-rails'
gem 'omniauth-google-oauth2'
初始化文件：
Rails.application.config.middleware.use OmniAuth::Builder do
provider :google_oauth2, ENV["GOOGLE_CLIENT_ID"],ENV["GOOGLE_CLIENT_SECRET"], skip_jwt: true
end
我以此为指导：Medium Guide
我现在已经在开发者工具上完成了两次设置应用程序的过程，以获取客户端 ID 和密钥，以防万一出现问题，并且两次我都遇到了同样的错误。我是编码新手，所以我确信这是非常愚蠢和明显的事情，但我似乎无法找到它。 感谢您的帮助！
编辑：
我的路线文件中也有：
get '/auth/:provider/callback' => 'sessions#omniauth'

【问题讨论】：
-
您是否将
get '/auth/:provider/callback' => 'sessions#omniauth'添加到config/routes.rb？routes.rb文件确定当有人访问您的应用程序中的路径时会发生什么（在本例中为/auth/google_oauth2）。错误告诉你 Rails 在路由列表中找不到任何告诉它该做什么的东西。 -
感谢您的回复，是的，我的路线中确实有这个问题，并且出现了同样的错误。我刚刚尝试使用 GitHub 登录进行设置，但实际上我得到了同样的无路由匹配错误......还有其他东西可以做到这一点吗？我的omniauth版本？添加要发布的路线信息。
-
您能否运行
rails routes并将结果添加到您的问题中？ -
添加到我的帖子的rails路线结果中。
-
另外，需要注意的是，我认为，我刚刚完成了使用 github 设置omniauth 的过程，并且出现了同样的“无路由匹配获取”错误...
