【问题描述】：

我正在使用 omniauth-facebook gem，当我转到 /auth/facebook 时，我得到了：

undefined method `path' for "https://graph.facebook.com":String

这让我发疯了。

config/initializers/omniauth.rb

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, [xxx], [xxx]
end

config/routes.rb

match 'auth/:provider/callback', to: 'sessions#create'
match 'auth/failure', to: redirect('/')

我使用的是 1.9.2

完整的堆栈跟踪：
