昨天买了 Agile Web Development with Rails， 今天就照着书上第四章所写很期待的写了个 Hello Rails。 不过碰到一个奇怪的问题， 我打 localhost:3000 是ｏｋ的，可见 server 有跑起来。 但我 ruby generate controller Say 之後， 也在 app/controllers/say_controller.rb 中定义了 hello app/views/say/ 底下也已照书中写好了 hello.rhtml， localhost:3000/say/hello 却是 Not found 请问可能是哪里出错了呢？ 我的作业系统是 Ubuntu 6.06 server 是用 webrick （ruby server webrick 所跑起来） 先谢谢各位的解惑，我自己搞有点久了… @"@ --- 以下是开 webrick 那个 terminal 所输出的错误讯息… #<NameError: uninitialized constant Breakpoint> ["../config/../vendor/rails/activesupport/lib/active_support/dependencies.rb:123:in `const_missing'", "../config/../vendor/rails/activesupport/lib/active_support/dependencies.rb:131:in `const_missing'", "../config/../vendor/rails/activesupport/lib/active_support/dependencies.rb:133:in `const_missing'", "../config/../vendor/rails/railties/lib/dispatcher.rb:75:in `reset_after_dispatch'", "../config/../vendor/rails/railties/lib/dispatcher.rb:46:in `dispatch'", "../config/../vendor/rails/railties/lib/webrick_server.rb:115:in `handle_dispatch'", "../config/../vendor/rails/railties/lib/webrick_server.rb:81:in `service'", "/usr/lib/ruby/1.8/webrick/httpserver.rb:104:in `service'", "/usr/lib/ruby/1.8/webrick/httpserver.rb:65:in `run'", "/usr/lib/ruby/1.8/webrick/server.rb:173:in `start_thread'", "/usr/lib/ruby/1.8/webrick/server.rb:162:in `start_thread'", "/usr/lib/ruby/1.8/webrick/server.rb:95:in `start'", "/usr/lib/ruby/1.8/webrick/server.rb:92:in `start'", "/usr/lib/ruby/1.8/webrick/server.rb:23:in `start'", "/usr/lib/ruby/1.8/webrick/server.rb:82:in `start'", "../config/../vendor/rails/railties/lib/webrick_server.rb:67:in `dispatch'", "../config/../vendor/rails/railties/lib/commands/servers/webrick.rb:59", "../config/../vendor/rails/activesupport/lib/active_support/dependencies.rb:147:in `require'", "../config/../vendor/rails/railties/lib/commands/server.rb:30", "server:3"] [2007-05-29 15:27:08] ERROR `/say/hello' not found. 127.0.0.1 - - [29/May/2007:15:27:08 CST] "GET /say/hello HTTP/1.1" 404 279 - -> /say/hello --
