使用Java运行Node.js

我需要使用Java运行一些node.js程序

我的代码看起来像这样

String filePath= "/home/gilles/eclipse-workspace/informationGewinnungApp/videotool/src/videotool.js"; String option1 = "-m resources/WetterBerich"; String option2 = "--bg_content resources/logo.png";

ProcessBuilder Pb =
           new ProcessBuilder("node",filePath+option1+option2);
         Map<String, String> env = pb.environment();
         env.put("VAR1", "myValue");
         env.remove("OTHERVAR");
         env.put("VAR2", env.get("VAR1") + "suffix");
         pb.directory(new File("/usr/bin"));
         File log = new File("log");
        // pb.redirectErrorStream(true);
         pb.redirectError(ProcessBuilder.Redirect.INHERIT);
         pb.redirectOutput(Redirect.appendTo(log));
         Process p = pb.start();
         assert pb.redirectInput() == Redirect.PIPE;
         assert pb.redirectOutput().file() == log;
         assert p.getInputStream().read() == -1;

但是我得到这个错误

module.js:549 throw err; ^
