Rails控制檯無效（RuntimeError）

Question

RuntimeError與Rails控制檯，Rails服務器按預期工作。

我使用的是Mac OSX SL

紅寶石版ruby 2.2.3p136 (2015-06-17 revision 50924) [i386-darwin10.0]

軌版本Rails 4.2.2

如果我使用bundle console與require_relative 'config/environment.rb'它正常工作

打開終端轉到您的項目目錄並運行它。

rails console 

或者如果您已經在您的項目中，則從那裏運行相同的命令。

iMac-di-Mario:store4 mario$ pwd /Users/mario/Sites/store4 $ rails console
