Ich folge den Schienen Cast Video here aber wenn ich versuche, meinen Server laufen bekomme ich einen Fehler "nicht initialisierte Konstante OmniAuth (NameError)". Wenn ich diese Datei entferne, startet der Server und die Homepage wird angezeigt, außer der Link zur Facebook Login Authentifizierung gibt einen Routing Fehler zurück "Keine Route stimmt mit [GET]"/auth/facebook "überein.omniauth facebook uninitialzed konstanter Fehler

Meine Frage ist ähnlich wie diese stackoverlfow Frage here aber mir ist im Entwicklungsmodus.

der gesamte Code ist das gleiche ich wodnering bin, was das ist. Bitte helfen Sie!

auch wenn die/initializers ist/Omniaut h.rb ist in seinem Ordner Ich kann das Benutzermodell nicht generieren Ich muss es entfernen, um dies zu tun?

Ich habe die neueste Version von omniauth-facebook Gem installiert und ran Bundle installieren.

'provider: facebook, ENV [ 'FACEBOOK_APP_ID'], ENV [ 'FACEBOOK_SECRET']' diese Zeile in 'initializers/devise.rb' Datei sein sollte, wenn Sie zufällig ersinnen verwenden. versuchen Sie auch, weitere Details hinzuzufügen – Abhinay

nicht nur mit den Schienen gegossen Beispiel und folgende Dokumentation auf Github für Omniauth und Omniauth-facebook –

hast du sowohl omniauth als auch omniauth-facebook in deiner gemfile? wie:

gem 'omniauth' 
gem 'omniauth-facebook'

Ja beide Edelsteine installiert sind. –

diese Antwort ist eigentlich richtig. Es war mein Mangel an Verständnis in der CMD-Zeile, und, den Edelstein IN die gemfile. nicht nur über die cmd-Zeile installieren. –
