私はRubyとpostgresqlに非常に慣れていません。
走ろうとすると
ruby scrpit/server, rake db:migrate, rake db:seed
私はこれを取得します。
Rails 2.3.11 application starting on http:/0.0.0.0:3000
warning: already initialized constant SESSION_SECRET
Faraday: you may want to install system_timer for reliable timeouts
/home/user/.rvm/gems/ruby-1.8.7-p371/gems/activerecord-.3.11/lib/active_record/connection_adapters/postgresql_adapter.rb:941:in `initialize': could not connect to server: Connection refused (PGError)
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
私はubuntu 12.04、ruby 1.8.7、rails-2.3、gem 1.5.3を使用しています
