<template>
  <main>
    <div class="part0"></div>
    <div class="part1">
      <canvas class="can0"></canvas>
    </div>
    <div class="part2">
      <div></div>

<script setup>
import {watch} from "vue";
import CanvasSelect from "canvas-select";

const can1 = new CanvasSelect('can0', 'https://unpkg.com/canvas-select@2.3.4/one.jpg');
let props = defineProps({
  int0: {
    type: Number,
    default: 0
  }
});
watch(props, (val) => {
  console.log(val.int0);
});
</script>

CanvasSelect的第一个参数既可以是css选择器，也可以是一个dom对象。你这里需要把"can0"改成".can0"
