Bundler不加载宝石

Question

我一直在使用Bundler的问题，并能够访问我的宝石，而无需要求他们在某个地方，因为config.gem曾经为我做过（据我所知）。在我的Rails 3应用程序，我定义我的Gemfile像这样：

clear_sources 
source "http://gemcutter.org" 
source "http://gems.github.com" 
bundle_path "vendor/bundler_gems" 

## Bundle edge rails: 
git "git://github.com/rails/arel.git" 
git "git://github.com/rails/rack.git" 
gem "rails", :git => "git://github.com/rails/rails.git" 

## Bundle 
gem "mongo_mapper", :git => "git://github.com/jnunemaker/mongomapper.git" 
gem "bluecloth", ">= 2.0.0" 

然后我跑gem bundle，它捆绑了这一切像预期。这里面包括内boot.rb的environment.rb文件时，它看起来是这样的：

# DO NOT MODIFY THIS FILE 
module Bundler 
file = File.expand_path(__FILE__) 
dir = File.dirname(file) 

    ENV["PATH"]  = "#{dir}/../../../../bin:#{ENV["PATH"]}" 
    ENV["RUBYOPT"] = "-r#{file} #{ENV["RUBYOPT"]}"

    def source_index.refresh! 
    super 
    Bundler.add_specs_to_index 
    end 
end 

但是，当我尝试访问任何我的宝石，例如中MongoMapper，Paperclip，Haml，等我得到：

NameError: uninitialized constant MongoMapper 

这同样适用于任何其他宝石。 Bundler是否不包含旧的Rails 2.0那样的宝石？或者是我的系统搞砸了？

任何帮助将不胜感激，谢谢！

您需要升级到Bundler上的最新版本。一旦你这样做，删除以前的版本有快速gem cleanup，解决您的Gemfile，然后做一个bundle lock然后将下面的代码添加到config/preinitializer.rb文件：

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 

# Auto-require all bundled libraries. 
Bundler.require
