若出现报错问题，请下载老版本的gsap

 "gsap": "^2.1.3",

代码如下：

<template>
  <div class="overall">
    <div class="text-box">
      <span class="dot"></span>
      <span class="dot"></span>
      <span class="dot"></span>
    </div>
    <svg height="0" width="0">
      <defs>
        <clipPath id="svgTextPath">
          <!-- textLength 文字的长度 此处对应容器的宽度  x y 为横纵坐标位置 -->
          <text x="0" y="180" textLength="700px">learning</text>
          <text x="200" y="300" textLength="250px">vue</text>
        </clipPath>
      </defs>
    </svg>
  </div>
</template>

<script>
import { TweenLite } from "gsap";
export default {

    this.move();
  },
  methods: {
    move() {
      let box = document.querySelector(".text-box");
      let dt = document.querySelectorAll(".dot");
      window.addEventListener("mousemove", function(e) {
        for (let i = 0; i < dt.length; i++) {
          //圆灯相对于 容器的坐标位置
          let x = e.pageX - box.offsetLeft - dt[i].offsetWidth / 2;
          let y = e.pageY - box.offsetTop - dt[i].offsetHeight / 2;
          TweenLite.to(dt[i], i + 0.2, {
            x: x,
            y: y,
            ease: Back.easeOut.config(1.7)
          });
