ruby-on-rails - 为什么我的 AptanaStudio3.0 无法调试 Rails 应用程序？

Question

这个问题我谷歌了将近一整天，还是没有答案。我的 ruby​​ 版本是 1.9.3，Rails 是 3.2.1，在 Mac 10.6 操作系统上。

现在我的 gem 列表是:

linecache19 (0.5.13)
ruby-debug-base19 (0.11.26)
ruby-debug-ide19 (0.4.12)
ruby-debug19 (0.11.6)
ruby_core_source (0.1.5)

我想我拥有了我可能需要的所有东西，但调试器仍然无法在我的 AptanaStudio3 上运行。

当我调试一个 ruby​​ 程序时，我得到了这个错误:

Fast Debugger (ruby-debug-ide 0.4.9) listens on :51042
Exception in DebugThread loop: undefined method `is_binary_data?' for "Array (10 element(s))":String

当我调试 Rails 服务器时，我得到了这个错误:

Fast Debugger (ruby-debug-ide 0.4.9) listens on :51175

任何人都可以提供帮助，非常感谢!

原来ruby-debug-ide和ruby-debug19玩的不好，是名字空间冲突的问题。要在 Aptana3 上进行调试(我的特定版本是 3.0.9)，就是从 Gemfile 中删除对 ruby​​-debug19 的引用并运行:

bundle install

确保它也从 Gemfile.lock 文件中删除。

希望这对您有所帮助。
