请问typscript中editor属性改如何定义？

Creator 2.x
#1

如题：
@ccclass
export class xxx extends cc.Component {

editor: {
    requireComponent: cc.Canvas
}

}

我尝试如上定义没有任何效果，求助~~

还需要添加一个装饰器，
const {ccclass, requireComponent} = cc._decorator;

@ccclass
@requireComponent(cc.Sprite)
class SpriteCtrl extends cc.Component {
    // ...
}

多谢多谢
