我正在将应用程序升级到Rails 3，并且已经逐步完成它，例如用gemfile中的相关gem替换所有旧插件 .
我似乎已经陷入困境，因为现在每当我尝试运行服务器时，我都会得到这个：
=> Booting WEBrick
=> Rails 3.0.0 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

/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)
我已经谷歌搜索了很多年，并得出结论，它仍然是因为其中一个插件，我只是无法弄清楚哪一个 . 我已经单独删除了每一个，但没有一个有所作为 .
我发现了这三个相似的问题，但它们并没有真正帮助我....
Stack level too deep error after running bundle update
SystemStackError at the rack level in Ruby 1.9.2, not 1.8.7
Stack level too deep trying to update from 3.0 to 3.1
