就是想体验GraalVM使用多语言的时候报错
public static void main(String[] args) {
System.out.println("Hello World from Java!");
Context context = Context.newBuilder().allowAllAccess(true).build();
context.eval("js", "print('Hello World from JavaScript!');");
context.eval("python", "print('Hello World from Python!')");
context.eval("ruby", "puts 'Hello World from Ruby!'");
}
报错信息

进程已结束，退出代码为 1
提示没安装 安装就好了(未配置graalvm的环境变量时, 应在graalvm包下的bin目录执行命令)
