在nodejs文档中，streams部分说我可以做fs.createReadStream(url || path)。但是，当我真正这样做时，它告诉我Error: ENOENT: no such file or directory。我只想将视频从可读流传输到可写流，但我坚持创建一个可读流。

我的代码：

const express = require('express')
const fs = require('fs')
const url = 'https://www.example.com/path/to/mp4Video.mp4'
const port = 3000

app.get('/video', (req, res) => {
    const readable = fs.createReadStream(url)
})
app.listen(port, () => {
    console.log('listening on port ' + port)
})

错误：

listening on port 3000
events.js:291
      throw er; // Unhandled 'error' event
      ^
