config.gemBundlerの使用に問題があり、（私が知る限り）以前のように、どこかで宝石を必要とせずに宝石にアクセスできるようになりました。Rails 3アプリでは、次のGemfileように定義しました。

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"

それから私は走りますgem bundle、それはそれをすべて期待通りに束ねます。その中にenvironment.rb含まれているファイル内boot.rbは次のようになります。

しかし、自分の宝石、たとえば、、などにアクセスしようとすると、次MongoMapperのようになります。PaperclipHaml

NameError: uninitialized constant MongoMapper

同じことが他の宝石にも当てはまります。Bundlerには、古いRails 2.0のようなgemは含まれていませんか？または、私のシステムで何かが台無しになっていますか？

どんな助けでもありがたいです、ありがとう！

Bundlerで最新バージョンにアップグレードする必要があります。これを行ったら、以前のバージョンをすばやく削除し、gem cleanupGemfileを修正してから、を実行してbundle lockから、次のコードをconfig/preinitializer.rbファイルに追加します。

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
