Question

我是Ruby noob（rube？），我在配置环境时无法让rake构建具有Java依赖性的东西。

我跑

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

并获取

/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)

(See full trace by running task with --trace)

PATH=/tmp/jruby-dodge:...确保which ruby实际解析为/opt/local/bin/jruby的符号链接。

是＆＃34;没有这样的文件要加载 - java＆＃34;与jruby有关吗？ java -version发出java version "1.6.0_29"因此我认为无法启动JVM。

当使用rake构建具有Java依赖关系的东西以供在jruby下使用时，rake是否在jruby或ruby下运行是否重要？如果是这样，我该如何指定？

看起来rvm让我玩弄多颗红宝石。

Installing RVM解释了如何安装它。

rvm install jruby

确保rvm了解jruby。

rvm use jruby

更新环境，以便ruby表示jruby。

宝石似乎是按照红宝石的味道安装的。

耙“没有这样的文件加载 - java”即使`哪个ruby` - ＆gt; JRuby的
