typescript 报错 Missing return type on function 编译不下去

class Snake {//表示蛇得元素head: HTMLElement;bodies: HTMLCollection; //蛇身体包括蛇头//获取蛇得容器element: HTMLElement;constructor() {this.element = document.getElementById("snikeAnimal");this.head = document.querySelector("#snikeAnimal > div") as HTMLElement;this.bodies = this.element.getElementsByTagName("div");}//获取蛇得坐标（蛇头）get X() {return this.head.offsetLeft;}get Y() {return this.head.offsetTop;}//设置蛇头得坐标***set X(value: number) {    // console.log(this.head.style.left)this.head.style.left = value + "px";}set Y(value: number) {this.head.style.top = value + "px";} ***//蛇增加身体得方法addBody() {//向element 中添加一个divthis.element.insertAdjacentHTML("beforebegin", "<div></div>");}
}```## set X set Y  编译出差在 .eslintrc.js文件中 rules添加  "@typescript-eslint/explicit-module-boundary-types": "off", // ts每个函数都要显式声明返回值
