这个问题可以换个方式处理，把图片流输出到html，相当于开一个web服务。

I got the same problem.

and now,I use the "qrcode" lib to fix it.

just like that.

const qrcode = require('qrcode')

robot.on('scan', (url, code) => {
    qrcode.toDataURL(url, function (err, base64) {
      var base64Data = base64.replace(/^data:image\/png;base64,/, '')
      fs.writeFile('qrcode/out.png', base64Data, 'base64',
      function (err, data) {
        if (err) {
          console.log('err', err)
        }
      })
    })

    console.log(`Scan QR Code to login: ${code}\n${url}`)
  })

then. I got a picture.

Maybe it's not a good solution, but it works.

I wish there was a better way : )

An alternative way to solve this problem: use our Wechaty Online QRCode Image Generator

const QRCODE_URL = 'https://wechaty.github.io/qrcode/'
const url = QRCODE_URL + 'https://login.weixin.qq.com/l/YYk19JaKVA=='

console.log(url)

Then you can visit the output URL to get the QR Code image.

Should add to the FAQ.

TBD.
