debugging - 无法为 jruby 运行调试器

Question

我尝试遵循 jruby 调试器的各种在线引用，但它不起作用。

我尝试过以下操作:首先更改为 root(不能像普通用户一样工作)然后:

jruby -S gem install ruby-debug-base


jruby -S gem install ruby-debug-base

但是下面的命令失败了:

jruby --debug -S rdebug ./classifier-wf.rb 

Gem::LoadError: Could not find columnize (>= 0.1) amongst [jdbc-mysql-5.1.24, rake-10.0.3, ruby-debug-0.10.4, ruby-debug-base-0.10.4-java]

             (root) at /opt/jruby-1.7.3/bin/rdebug:22

我正在运行 jruby 1.7.3。谢谢。

使用 Pry而不是其他调试器 gem，您很快就会对它上瘾。
