ruby-on-rails - 在 OSX Mavericks 之后无法加载此类文件 -- script/../config/boot (LoadError)

Question

我昨天在 Rails 应用程序 (v2.3) 上开发了一个 ruby​​，并决定将我的 iMac 更新到 OSX Mavericks。现在，每次我尝试在本地运行我的应用程序时，都会收到以下错误。有谁知道这是什么原因造成的？

像这样运行:

script/server -e development

错误:

 /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- script/../config/boot (LoadError)
        from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require'
        from script/server:2:in `<main>'

脚本/服务器(文件)

#!/usr/bin/env ruby
require File.dirname(__FILE__) + '/../config/boot'
require 'commands/server'

在安装 OSX Mavericks 之前它运行良好。

我注意到的事情:

• 现在安装的ruby版本是2.0(之前是v1.8.7)

仅供引用:我对 Rails 还是很陌生。

安装 RVM 后:

好的，所以我设置了 RVM 并确保安装了 ruby​​ (1.8.7) 和 rails (2.3.11) 版本并将其配置为默认版本。

已安装的 RVM:

curl -L https://get.rvm.io | bash -s stable --rails

安装 Ruby 1.8.7:

rvm install ruby-1.8.7-p374

设置v1.8.7为默认版本:

rvm --default use 1.8.7

安装 Rails v2.3.11:

gem install rails -v 2.3.11

安装系统中的所有gem

rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system

现在，当我运行我的应用程序时，出现以下错误:(我错过了什么？)

从这个问题中要了解的主要事情是，您不能依赖于您的 ruby​​ 版本或您在 ruby​​ 项目中使用的 gem 的操作系统。当您创建其他 ruby​​ 应用程序时，您可能会再次遇到这个问题。

-  To manage the gems use Bundler
   Bundler maintains a consistent environment for each ruby applications. 

-  To manage the Ruby versions use rbenv or rvm
