瑞克“没有这样的文件要加载-Java"即使是“哪个红宝石"->茹比 [英] Rake "no such file to load -- java" even when `which ruby` -> jruby

问题描述

我是Ruby noob(rube?)，无法配置我的环境以获取rake来构建具有Java依赖项的内容.

I am a Ruby noob (rube?) and am having trouble configuring my environment to get rake to build something with a Java dependency.

我跑步

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

并获得

PATH=/tmp/jruby-dodge:...确保which ruby实际上解析为指向/opt/local/bin/jruby的符号链接.

The PATH=/tmp/jruby-dodge:... makes sure that which ruby actually resolves to a symlink to /opt/local/bin/jruby.

与jruby相关的没有要加载的文件-java"吗? java -version发出java version "1.6.0_29"，所以我认为启动JVM不会失败.

Is "no such file to load -- java" related to jruby at all? java -version emits java version "1.6.0_29" so I don't think there is a failure to start up a JVM.

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

When using rake to build something with Java dependencies for use under jruby, does it matter whether rake is running under jruby or ruby? If so, how do I specify that?

推荐答案

rvm似乎让我玩弄了多个红宝石.

It looks like rvm lets me juggle multiple rubies.

安装RVM 说明了如何安装它.

rvm install jruby

确保rvm了解jruby.

rvm use jruby

更新环境，以使ruby表示jruby.

宝石似乎是按红宝石的口味来安装的.

Gems seem to be installed per-flavor of ruby.
