'Ich konnte pg-0.12.2 in keiner der Quellen finden' wenn ich rspec starte

Question

Ich arbeite an der Erstellung der Twitter-Klon-App in Hartls Rails Tutorial. Ich klonte meinen Git Repo (https://github.com/stewartmccoy/rails_tutorial) und legte Code auf meinen PC, der vorher auf meinem Arbeitscomputer war. Meine Entwicklerumgebung könnte also etwas anders sein als in meiner Gemfile angegeben.

Meine Umgebung: Mac OS 10.6.8 Rails 3.2.13 Rubin 1.9.3p392 (2013.02.22 Revision 39386) [x86_64-darwin10.8.0]

end 

Wie dem auch sei, ich versuche, den Test nur nach Listing 8 laufen.18 (http://ruby.railstutorial.org/chapters/sign-in-sign-out#sec-reviewing_form_submission):

$ bundle exec rspec spec/models/user_spec.rb 

Und ich bekomme diese Fehlermeldung:

Could not find pg-0.12.2 in any of the sources 
Run `bundle install` to install missing gems. 

Also, ich laufe bundle install und und erhalten diesen Fehler:

An error occurred while installing pg (0.12.2), and Bundler cannot continue. 
Make sure that `gem install pg -v '0.12.2'` succeeds before bundling. 

Schließlich habe ich versucht PATH=$PATH:/Library/PostgreSQL/9.2/bin sudo gem install pg und bekam :

Vorschläge?

Vielen Dank im Voraus für Ihre Hilfe!

Answer 1

Sie sollten überprüfen, welche Adapter Sie auf config/database.yml haben. Wahrscheinlich haben Sie den Postgres- oder Pg-Adapter mit der Test Umgebung eingerichtet.

jedoch auf Ihrem Gemfile, haben Sie Setup Postgres nur für die Produktion:

group :production do 
    gem 'pg', '0.12.2' 
end 

, wenn Sie die Testumgebung hinzufügen und Bündel erneut ausführen, sollte es funktionieren:

group :test, :production do 
    gem 'pg', '0.12.2' 
end 

Auch Siehe die Lösung von this answer:

Versuchen Sie, den Edelstein mit diesem Befehl zu installieren:

gem install pg -- --with-pg-config= 'PATH_TO_YOUR_PG_CONFIG' 

Wenn Sie nicht wissen, wo Ihr pg_config ist, führen Sie diesen Befehl ein:

which pg_config 

BTW, hast du bereits Postgres auf Ihrem Desktop installieren? Alles, was Sie brauchen, ist das Postgres-Entwicklungspaket, um den Edelstein zu installieren.
