是否可以从Java中的ScriptEngineManager设置我的jruby的gem路径?问题是我使用的是压缩的jruby解释器(jruby-complete.jar)并且不可能使用预先安装的gem获得此包,所以我正在尝试使用ScriptEngineManager从Java运行jruby并重定向宝石的路径,我已经安装在我的硬盘上。

示例:

public class Main {
    public static void main(String[] args) {
        StringBuffer jruby = null;
        ScriptEngine runtime = null;

        try {
            runtime = new ScriptEngineManager().getEngineByName("jruby");
            jruby = new StringBuffer();

            jruby.append("require 'ruby/Libraries.rb'");
            jruby.append("\r\n");
            jruby.append("if __FILE__ == $0");
            jruby.append("\r\n");
            jruby.append("\tzkan = ZKANWritter.new(\"");
            jruby.append("G:/path/output.xls");
            jruby.append("\",\"");
            jruby.append("G:/path/kanban.txt");
            jruby.append("\",\"//path/LT CUU.tab\")");
            jruby.append("\r\n");
            jruby.append("\tzkan.write(2)");
            jruby.append("\r\n");
            jruby.append("end");

            runtime.eval(jruby.toString());
        } catch (Exception ex) {
            System.out.println("Error: " + ex.getMessage());
        }
    }
}

先谢谢

我刚刚设置了环境变量RUBYLIB& GEM_HOME以编程方式来自ruby:

ENV["RUBYLIB"] = "lib/libs"
ENV["GEM_HOME"] = "lib/gems"

require "library-1.rb"
...
require "library-n.rb"
