It isn't a bug in Bundler (or Rails), It's a bug (?!) in gems system, I think... So.. I also have gem 'rawr', which have file 'bundler.rb' and gems system load it instead of 'bundler/../bundler.rb'.
这不是 Bundler（或 Rails）中的错误，而是 gems 系统中的错误（？！），我想......所以......我也有 gem 'rawr'，它有文件 'bundler.rb' 和 gems系统加载它而不是'bundler/../bundler.rb'。
I removed rawr, but now I can't use jemini... But my problem closed now.
我删除了rawr，但现在我不能使用jemini……但我的问题现在已经解决了。

it works after adding:
添加后即可使用：
gem install bundler
and after adding:
添加后：
gem 'bundler'
in line 2 in config/boot.rb (just after require 'rubygems')
在 config/boot.rb 的第 2 行中（就在 require 'rubygems' 之后）

Please confirm paths of ruby and rake command.
请确认ruby和rake命令的路径。
$ which ruby
/usr/bin/ruby
$ which rake
/usr/local/bin/rake
I got the same error. In my case, I installed Rails with /usr/bin/ruby, but rake uses /usr/local/bin/ruby. This is why I got the error related to Bundler.
我得到了同样的错误。就我而言，我使用 /usr/bin/ruby 安装 Rails，但 rake 使用 /usr/local/bin/ruby。这就是我收到与 Bundler 相关的错误的原因。

I had upgraded my rubygems to 1.5.0 but I needed to also put ruby-1.9.2-p180 as my default ruby version in RVM. This did the trick for me.
我已将 rubygems 升级到 1.5.0，但我还需要将 ruby-1.9.2-p180 作为我在 RVM 中的默认 ruby 版本。这对我有用。

I had the problem on Mac, because several gems (including bundler) were installed in "/opt/local/lib/ruby/gems/1.8", which is loaded by default by RubyGems in irb, but not in rake.
我在 Mac 上遇到了这个问题，因为在“/opt/local/lib/ruby/gems/1.8”中安装了几个 gems（包括 bundler），它默认由 irb 中的 RubyGems 加载，但不在 rake 中。
Here is how I fixed it, it is probably not perfect, but at least it works:
这是我修复它的方法，它可能并不完美，但至少它有效：
Find the path(s) you need by going in irband doing
require 'rubygems' Gem.path => ["/Users/joel/.gem/ruby/1.8", "/opt/local/lib/ruby/gems/1.8"]These are the default paths, so if everything works for you in irb they're good.
Now, in boot.rb, add (use your paths if they differ of course)
Gem.path.push "/opt/local/lib/ruby/gems/1.8" Gem::Specification.find_by_name('bundler').activateRight after
require 'rubygems'
通过进入irb并执行，找到您需要的路径
require 'rubygems' Gem.path => ["/Users/joel/.gem/ruby/1.8", "/opt/local/lib/ruby/gems/1.8"]这些是默认路径，所以如果在 irb 中一切正常，它们就很好。
现在，在boot.rb 中，添加（当然，如果它们不同，请使用您的路径）
Gem.path.push "/opt/local/lib/ruby/gems/1.8" Gem::Specification.find_by_name('bundler').activate紧随其后
require 'rubygems'
Hope this solves it for you, at least I'm glad I fixed it for me so I can finally use Rails 3 !
希望这可以为您解决问题，至少我很高兴我为我修复了它，这样我终于可以使用 Rails 3 了！
