Ruby on Rails：Code Rot

Question

长话短说，我启动了我的系统，当我告诉Rubymine运行开发时，我得到了这个结果。

/home/barnabus/.rvm/rubies/ruby-1.9.3-p385/bin/ruby -e $stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) /home/barnabus/Projects/Ruby/houston/script/rails server -b 0.0.0.0 -p 3000 -e development

我从来没有见过这个错误，我真的不知道在哪里以及如何继续，因为有太多这是在框架代码发生的事情。

任何帮助，非常感谢。

诀窍是看到它是一个正在发展的宝石。所以我去了并卸载了这个宝石。

bundle exec gem uninstall actionpack 

它抱怨依赖关系。

You have requested to uninstall the gem: 
actionpack-3.2.8 
actionmailer-3.2.8 depends on [actionpack (= 3.2.8)] 
railties-3.2.8 depends on [actionpack (= 3.2.8)] 
rails-3.2.8 depends on [actionpack (= 3.2.8)] 
rspec-rails-2.12.2 depends on [actionpack (>= 3.0)] 
simple_form-2.0.4 depends on [actionpack (~> 3.0)] 
If you remove this gems, one or more dependencies will not be met. 
Continue with Uninstall? [Yn] Y 

但这并不重要，因为我们要重新安装它。

Successfully uninstalled actionpack-3.2.8 
ERROR: While executing gem ... (NoMethodError) 
undefined method `delete' for #<Bundler::SpecSet:0x00000002c53b20> 

之后做我不得不重新安装它，这样做，我只是跑

bundle install 

我回到了正轨。
