昨天我在rails应用程序（v2.3）上使用ruby进行开发，并决定将我的iMac更新为OSX Mavericks。现在，每次我尝试在本地运行我的应用程序时，都会出现以下错误。有谁知道造成这种情况的原因是什么？
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之前它工作正常。
我注意到的事情：
仅供参考：我还是铁杆的新手。
安装RVM后： 好的，我设置了RVM，并确保安装并配置了ruby（1.8.7）和rails（2.3.11）的版本作为默认值。
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
将v1.8.7设置为默认版本：
rvm --default use 1.8.7
安装Rails v2.3.11：
gem install rails -v 2.3.11
从系统安装所有宝石
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，我收到以下错误:(我错过了什么？）

从这个问题中要理解的主要问题是，你不能依赖于ruby版本的操作系统或你在ruby项目中使用的gem。当您创建其他ruby应用程序时，您可能会再次遇到麻烦。
- To manage the gems use Bundler
Bundler maintains a consistent environment for each ruby applications.
- To manage the Ruby versions use rbenv or rvm
