無法在3.2.6系統上啓動Rails服務器

Question

我有一個嘗試啓動我的Rails項目的主要問題。我正在使用rails 4.0.0項目並嘗試在Rails 3.2.6系統上運行它。我的工作環境使用Rails 3.2.6環境，我的系統在家裏工作（Mac mini）使用rails 4.自那時起我開始使用我的Linux筆記本電腦，它具有Rails 3.2.6，就像我的僱主使用的一樣。

這是我的錯誤跟蹤：

這裏是我的environment.rb文件中：

# Load the Rails application. 
require File.expand_path('../application', __FILE__) 

# Initialize the Rails application. 
MockDevices2::Application.initialize! 

這裏是我的boot.rb文件：

# Set up gems listed in the Gemfile. 
ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', __FILE__) 

require 'bundler/setup' if File.exists?(ENV['BUNDLE_GEMFILE']) 
require 'thread'

Answer 1

你可以發佈你的routes.rb嗎？好像問題出在

from /home/ironmantis7x/RoR_projects/mock_devices2/config/routes.rb:10:in `block in <top (required)>' 

這發生在我身上，問題是，我使用的

root 'welcome#index' 

代替

root to: 'welcome#index' 

和軌道3不一樣，
