奇怪的語法錯誤不一致JRuby中

我遇到在OS X和Ubuntu的生產主機上運行的JRuby之間的不一致。在我的生產主機，我有以下幾點：奇怪的語法錯誤不一致JRuby中

~ $ java -version 
java version "1.6.0_22" 
Java(TM) SE Runtime Environment (build 1.6.0_22-b04) 
Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03, mixed mode) 
~ $ rvm use jruby-1.6.8 
Using /home/ubuntu/.rvm/gems/jruby-1.6.8 
~ $ rvm list rubies 

rvm rubies 

=> jruby-1.6.8 [ x86_64 ] 
* ruby-1.9.2-p318 [ x86_64 ] 

# => - current 
# =* - current && default 
# * - default 

~ $ irb 
jruby-1.6.8 :001 > def foo(*args) 
jruby-1.6.8 :002?> end 
=> nil 
jruby-1.6.8 :003 > foo(1, 
jruby-1.6.8 :004 >   2, 
jruby-1.6.8 :005 >  ) 
SyntaxError: (irb):5: syntax error, unexpected tRPAREN 

    )

這是（我相信）有效的Ruby代碼，但更重要的是，它似乎是有效的JRuby的代碼，因爲它適用於我的OS X框細：

~ $ java -version 
java version "1.6.0_35" 
Java(TM) SE Runtime Environment (build 1.6.0_35-b10-428-11M3811) 
Java HotSpot(TM) 64-Bit Server VM (build 20.10-b01-428, mixed mode) 
~ $ rvm use jruby-1.6.8 
Using /Users/lwiman/.rvm/gems/jruby-1.6.8 
~ $ rvm list rubies 

rvm rubies 

    jruby-1.6.4 [ x86_64 ] 
    jruby-1.6.7 [ x86_64 ] 
=> jruby-1.6.8 [ x86_64 ] 
* ruby-1.9.2-p290 [ x86_64 ] 
    ruby-1.9.3-p194 [ x86_64 ] 

# => - current 
# =* - current && default 
# * - default 

~ $ irb 
jruby-1.6.8 :001 > def foo(*args) 
jruby-1.6.8 :002?> end 
=> nil 
jruby-1.6.8 :003 > foo(1, 
jruby-1.6.8 :004 >   2, 
jruby-1.6.8 :005 >  ) 
=> nil 
jruby-1.6.8 :006 >

解決此問題的任何幫助將不勝感激！

解決它！（在昨天工作了好幾個小時，在把它放到StackOverflow上20分鐘後解決了它，問題是由於某種原因，Jruby默認爲Ruby 1.8模式，我不完全確定它爲什麼在我的OS X計算機上工作，但是加入compat.version=1.9我.jrubyrc文件的伎倆見：https://github.com/jruby/jruby/wiki/ConfiguringJRuby

的JRuby 1.7.0吼叫默認情況下是在1.8模式下，從1.7.0 JRuby的將默認爲1.9模式 – mpapis

默認在1.9模式下安裝JRuby： 'RVM安裝JRuby -C -Djruby.default.ruby.version = 1.9' http://samuel.kadolph.com/2011/10/jruby-with-1-9-mode-as-the-default-with- rvm/ – RecursivelyIronic

rm有一個快捷方式，適用於jruby和rbx：'rvm install jruby --1.9' – mpapis
