耙「沒有這樣的文件加載-java」即使當`ruby` - > jruby

我是一個Ruby noob（rube？），並且在配置我的環境時遇到了問題，使rake可以構建一些具有Java依賴性的東西。耙「沒有這樣的文件加載-java」即使當`ruby` - > jruby

我跑

$ PATH=/tmp/jruby-dodge:"$PATH" rake

，並得到

/opt/local/bin/ruby -S rspec spec/contextual_spec.rb 
/opt/local/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- java (LoadError)

rake aborted! 
/opt/local/bin/ruby -S rspec spec/contextual_spec.rb failed 

Tasks: TOP => default => spec 
(See full trace by running task with --trace)

的PATH=/tmp/jruby-dodge:...可以確保which ruby實際上解析爲一個符號鏈接/opt/local/bin/jruby。

是否「根本沒有這樣的文件加載 - java」與jruby有關？ java -version發出java version "1.6.0_29"，所以我認爲沒有啓動JVM失敗。

當使用rake構建Java依賴關係的東西在jruby下使用時，rake是在jruby還是ruby下運行？如果是這樣，我該如何指定？

它看起來像rvm讓我玩弄多個紅寶石。

Installing RVM說明如何安裝它。

rvm install jruby

確保rvm知道jruby。

rvm use jruby

更新環境使ruby表示jruby。

寶石似乎被安裝每個味道的紅寶石。
