Problemi durante il tentativo di avviare Bind Server

Question

Scusa se questa è una brutta domanda, sto cercando di impostare inizialmente rotaie, quindi non so davvero cosa sto facendo.Nel tutorial che sto seguendo arriva a un punto in cui è dire di eseguire "Server Rails", tuttavia questo sta restituendo alcuni risultati imprevisti. (Vedi sotto)

Macbookpro:First Cameron$ sudo rails server

Scusa se questo non è necessario, ma non sono davvero sicuro cosa fare con esso.

Answer 1

Non penso che tu sia solo in questo errore. Assicurati di coordinare le vostre versioni Gem e ancora meglio se specificare le versioni dei tuoi binari e Gemme Ruby per evitare potenziali conflitti nelle versioni.

Pubblicare il tuo Gemfile sarebbe utile, ma senza vederlo, direi di specificare la tua versione Ruby nella parte superiore del tuo Gemfile come:

source 'https://rubygems.org'
ruby '2.0.0'

.

Quindi specificare la versione delle rotaie.Mentre non ho avuto problemi a fornire solo:

gem 'rails'

.

Potresti essere sicuro e specificare una versione come:

gem 'rails', '4.0.2'

.

Quindi eseguire: bundle install per la tua app.

Answer 2

Dai un'occhiata al seguente tutorial.Mi rendo conto che è per Windows, tuttavia ha risolto tutti i problemi iniziali che stavo avendo con la mia prima installazione.

Il punto principale che mi ha aiutato ad installare perfettamente era;

Eseguire gem update su una nuova installazione per assicurarsi che tutto sia aggiornato
