Question

我是一名RoR新手，尝试使用readme运行todos示例。运行捆绑工作正常：

$ bundle
Using rake (0.9.2.2) 
Using chunky_png (1.2.5) 
Using fssm (0.2.8.1) 
Using sass (3.1.15) 
Using compass (0.11.7) 
Using json (1.6.5) 
Using rack (1.4.1) 
Using thor (0.14.6) 
Using rake-pipeline (0.6.0) from https://github.com/livingsocial/rake-pipeline.git (at master) 
Using rake-pipeline-web-filters (0.6.0) from https://github.com/wycats/rake-pipeline-web-filters.git (at master) 
Using bundler (1.0.22) 
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

捆绑exec rakep服务器对我不起作用：

$ bundle exec rakep server

任何想法为什么？

目前，Rake Pipeline仅在Ruby 1.9下运行。这可能是可修复的，应该被认为是Rake Pipeline中的一个错误。无论如何，我建议将Ruby 1.9.3与RVM一起使用。
