[LayaAirIDE 2.0]prop 识别不到

新手，刚学习，是我哪里弄错了吗，请大佬们解答下小弟遇到的问题，谢谢
 
已经申明了prop，IDE中已经识别到了，但vscode报未定义，IDE F8编译时也不通过
 
代码：
export default class Index extends Laya.Script {
    /* @prop {name: speed, tips: "速度", type: Number, default: 10} */ 
    constructor() {
        super();
    } 
    onAwake() {
        console.log("场景渲染完成", this.speed);
    }
}
 
IDE中报错：

[15:26:35] Using gulpfile E:\myLaya\demo2\.laya\compile.js
