Problem mit posgresql - db: create flags Fehler

Question

Ich versuche, eine neue Schienen App mit pg einzurichten. Der Edelstein installiert, aber wenn ich rails db:create laufen bekomme ich diesen Fehler in meinem Terminal:

Specified 'postgresql' for database adapter, but the gem is not loaded. Add `gem 'pg'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord). 
    Couldn't create database for {"adapter"=>"postgresql", "pool"=>5, "timeout"=>5000, "database"=>"db/spaces_development"} 
    rails aborted! 
    Gem::LoadError: Specified 'postgresql' for database adapter, but the gem is not loaded. Add `gem 'pg'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord). 

Das ist mein Gemfile & database.yml hat jemand bekam eine Ahnung, was ich falsch mache?

Answer 1

Typo: gem 'pq', ist, was Sie in Ihrem gemfile haben, während es gem 'pg'

Auch sollte nicht vergessen bundle install um sicherzustellen, dass das Schmuckstück zu laufen ist installiert und bereit zu rocken & roll
