【问题描述】：
过去两天我一直在转圈圈。我正在将应用程序从 Rails 2.3.12 升级到 Rails 3.0.0。它在 ruby 1.9.3 上。
我正在慢慢研究供应商/插件并将它们更新为相关的宝石。
我的问题是这样的：当我尝试运行服务器时出现此错误：
/Users/camillavk/.rvm/gems/ruby-1.9.3-p551@rails3/gems/rack-1.2.8/lib/rack/builder.rb:35: stack level too deep (SystemStackError)
经过大量搜索后，我了解到这可能是因为我运行的是旧版本的 Rack (1.2.8)。然后我尝试更新它并收到此错误：
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
bundler (~> 1.0.0) ruby
Current Bundler version:
bundler (1.8.2)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
为什么我要在我的 Gemfile 中指定 bundler (~> 1.0.0)？因为这个错误：
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
rails (= 3.0.0) ruby depends on
bundler (~> 1.0.0) ruby
Current Bundler version:
bundler (1.8.2)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running `gem install bundler`?
但是我在当天早些时候遇到了这个问题，我知道我可以使用这个来捆绑更新和捆绑安装：
bundle _1.0.22_ install
强制它使用它需要的 bundler 版本（仅仅在 Gemfile 中指定它是不够的，你可以在上面的错误中看到...）
所以我使用它。但它不再起作用，而是给我这个错误：

我在这里找到的与此相关的所有其他问题在错误中都有一个额外的行，说明哪个宝石正在破坏它......我没有，所以不知道如何开始解决这个问题。
我是不是把自己挖进了一个深坑，再也出不来了？有没有人对如何开始解决这个问题有任何想法或建议？ Rails 3 显然想要 Bundler 1.0.22，但我看到的每个答案都告诉我升级 Bundler！
以防万一有人认为他们能弄明白，这是我的 gemfile：
