Errore durante il tentativo di angularjs con rails: metodo non definito `register_engine 'per nil: NilClass (NoMethodError)

Sono nuovo sia per angularjs che per le rotaie. Nella mia nuova società dobbiamo usare il rubino su rotaie con angularjs. Dopo aver preso le esercitazioni per angularjs e ruby su rail separatamente, stavo provando come entrambi avrebbero funzionato insieme usando il seguente link: https://thinkster.io/angular-rails#generating-activerecord-models Dopo aver seguito tutti i passaggi fino all'argomento "Integrazione del front-end con la pipeline di asset" (inclusi i passaggi in questo argomento) quando ho eseguito il comando rotaie s il seguente errore viene:Errore durante il tentativo di angularjs con rails: metodo non definito `register_engine 'per nil: NilClass (NoMethodError)

Utilizzando rotaie versione 4.2.5

seguito è un frammento del Gemfile:

source 'https://rubygems.org' 

    gem 'angular-rails-templates' 

    gem 'rails', '4.2.5' 

    gem 'sqlite3' 

    gem 'sass-rails', '~> 5.0' 

    gem 'uglifier', '>= 1.3.0' 

    gem 'jbuilder', '~> 2.0' 

    gem 'sdoc', '~> 0.4.0', group: :doc 


    group :development, :test do 

     gem 'byebug' 

    end 

group :development do 

gem 'web-console', '~> 2.0' 

gem 'spring' 

end

Hai già risolto il problema effettuando il downgrade della gemma come spiegato nella mia risposta? – Mario

Se la risposta ha risolto il tuo problema, dovresti accettarlo, altrimenti puoi chiedere di più. @Ashi – Mario

@marcpt nessuno dei suggerimenti ha funzionato. Ho eliminato tutto e ho ripreso i passaggi e ha funzionato. Sembra che abbia seguito qualsiasi passaggio in modo errato o mancato. Grazie per l'aiuto! – Ashi

Ho avuto lo stesso problema. Era un problema relativo ai "pignoni". Prova ad installare una versione precedente aggiungendo gem 'sprockets', '2.12.3' al tuo file gem e quindi aggiorna le tue gemme eseguendo bundle update. Ha funzionato per me.

2.12.4 ha risolto anche il problema per me, ma nessuno dei seguenti: 3.0.3, 3.1.0, 3.2.0, 3.3.5, 3.4.1. 3.5.2. A proposito, non sto usando AngularJS. –

Perché si riferisce a 'socket'? –

@NewAlexandria è 'pignoni' non' prese ' –
