使用rails控制台的RuntimeError，rails服务器按预期工作。
我正在使用Mac OSX SL
ruby版本ruby 2.2.3p136 (2015-06-17 revision 50924) [i386-darwin10.0]
rails version Rails 4.2.2
如果我将bundle console与require_relative 'config/environment.rb'一起使用，则通常可以使用
/usr/local/lib/ruby/gems/2.2.0/gems/railties-4.2.2/lib/rails/application.rb:351:in `initialize!': Application has been already initialized. (RuntimeError)

打开终端并移至项目目录并运行它。
rails console
或者如果您已经在项目中，则从那里运行相同的命令。
iMac-di-Mario:store4 mario$ pwd /Users/mario/Sites/store4 $ rails console
