亲，你示例代码都错了吧，应该是 myCanvas

[H246802]

import QrCodeWithLogo from 'qr-code-with-logo'
import LocalImage from './Avatar.png'

const myCanvas = document.createElement('canvas')
//  append应该是myCanvas
document.getElementsByTagName('body')[0].appendChild(canvas)

QrCodeWithLogo.toCanvas({
  canvas: myCanvas,
  content: 'https://cdn.blog.cloudself.cn',
  width: 380,
  logo: {
    src: LocalImage,
    // src: 'https://cdn.blog.cloudself.cn/images/avatar.png',
    radius: 8
  }
})
