升级到 jruby 1.7.0 并使用 ruby​​-debug 后，我得到以下输出：

[INFO] Unable to bind key for unsupported operation: backward-delete-word
[INFO] Unable to bind key for unsupported operation: backward-delete-word
[INFO] Unable to bind key for unsupported operation: down-history
[INFO] Unable to bind key for unsupported operation: up-history

[INFO] Unable to bind key for unsupported operation: up-history
[INFO] Unable to bind key for unsupported operation: down-history
(rdb:1)

并且调试器没有响应，我只能执行 <CTRL>-Z 来退出并终止进程。目前谷歌搜索这些行中的任何一个目前都出现零结果，所以完全不确定在哪里看。

我有同样的问题，偶然发现了一个解决方法。它也可能对你有用。

当您收到提示时，按“v”并输入，您将处于调试器模式！
