我想使用当前版本的bundler（从 0.8 到 0.9 有很多变化）来管理我的 Rails 应用程序的 gem。首先，我在Gemfileapp 文件夹的根目录中创建了一个并添加了所有需要的 gem。然后我将（按照手册中的建议）将以下代码放入我的config/environment.rb：

begin
  # Require the preresolved locked set of gems.
  require File.expand_path('../.bundle/environment', __FILE__)
rescue LoadError
  # Fallback on doing the resolve at runtime.
  require "rubygems"
  require "bundler"
  Bundler.setup
end

bundle install完成后似乎工作正常Your bundle is complete!。但是在启动我的应用程序时，我收到以下错误：

$ ruby script/server

这里有什么问题？

Arrrg，刚按下发送按钮，就有了解决问题的想法。捆绑器手册说：“[...] 在代码的开头包含以下内容。” 对于 Rails 应用程序，您必须将提到的部分放在底部config/environment.rb才能正确设置所有内容：

RAILS_GEM_VERSION = '2.3.5' unless defined? RAILS_GEM_VERSION

require File.join(File.dirname(__FILE__), 'boot')

Rails::Initializer.run do |config|
...
end

# Put the bundler related stuff here!
begin
  # Require the preresolved locked set of gems.
  require File.expand_path('../.bundle/environment', __FILE__)
rescue LoadError
  # Fallback on doing the resolve at runtime.
  require "rubygems"
  require "bundler"
  Bundler.setup
end
