我使用的omniauth Facebook的寶石和去/auth/facebook當我越來越：Rails的omniauth Facebook的未定義的方法`路徑」爲‘https://graph.facebook.com’：字符串
undefined method `path' for "https://graph.facebook.com":String
這讓我感到非常緊張。
配置/初始化/ omniauth.rb
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, [xxx], [xxx]
end
的config/routes.rb中
match 'auth/:provider/callback', to: 'sessions#create'
match 'auth/failure', to: redirect('/')
我使用1.9.2
