【问题描述】：

我昨天在一个 ruby on rails 应用程序 (v2.3) 上进行开发，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）

仅供参考：我对 Rails 还是很陌生。

安装 RVM 后：

好的，所以我设置了 RVM 并确保 ruby (1.8.7) 和 rails (2.3.11) 的版本已安装并配置为默认值。

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

从系统中安装所有的 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，我收到以下错误：（我错过了什么？）

【问题讨论】：

您是否重新安装了rails？例如。通过bundle install
是的，ruby 的默认版本已更改，您的所有 gem 都需要重新安装/重建。如果在 mac 上开发，您可能需要查看 int rvm 或 rbenv 以保留您的 ruby / gems 与系统 ruby 分开，因此您不受这些更改的影响，并且可以更好地控制版本等。
我现在正在设置 RVM。我会及时通知你进展情况。
好的，所以我用我为解决这个问题而采取的步骤更新了我的问题。（设置 RVM）
如果您使用的是 RVM，您可能需要rvm implode 并从最新版本重新开始。

【解决方案1】：

从这个问题中要了解的主要一点是，您不能依赖操作系统来获取您的 ruby 版本或您在 ruby 项目中使用的 gem。当您创建额外的 ruby 应用程序时，您可能会再次遇到此问题。

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

-  To manage the Ruby versions use rbenv or rvm
