今天,我給了JRuby一個嘗試與Apache的Mahout一起使用它。但是我對調試器有問題。當我把debugger
陳述放在一個特定的地方時,它並不止於此。它在腳本末尾停止,然後當然沒有變量可用。這是我的Gemfile:JRuby調試器無法按預期工作
source 'https://rubygems.org'
platform :jruby do
gem "jruby_mahout"
gem "ruby-debug"
end
這是腳本:
require 'rubygems'
require 'ruby-debug'
puts "I am called"
debugger
puts "I should not be called before the debugger"
但輸出是:
I am called
/usr/local/rvm/gems/[email protected]/gems/ruby-debug-base-0.10.4-java/lib/ruby-debug-base.rb:215 warning: tracing (e.g. set_trace_func) will not capture all events without --debug flag
I should not be called
/usr/local/rvm/gems/[email protected]/gems/ruby-debug-0.10.4/cli/ruby-debug/interface.rb:129
finalize if respond_to?(:finalize)
(rdb:1)
我不知道爲什麼會有這樣的警告tracing (e.g. set_trace_func) will not capture all events without --debug flag
,因爲我開始與腳本jruby test.rb --debug
我安裝JRuby 1.7.3與RVM在我的OS X 10.8,並呼籲jruby -version
當我得到這樣的輸出:
jruby 1.7.3 (1.9.3p385) 2013-02-21 dac429b on Java HotSpot(TM) 64-Bit Server VM 1.6.0_43-b01-447-11M4203 [darwin-x86_64]
NameError: undefined local variable or method `rsion' for main:Object
(root) at -e:1
也許安裝壞了,或者說我做某事錯。任何建議如何解決這個問題?
