node util.log

If you experience the error “util.pump is not a function” while running a Node.js app or a Node.js snippet, it’s because the app code is too old for the current Node.js runtime.

如果在运行Node.js应用程序或Node.js代码段时遇到错误“ util.pump不是函数”，这是因为该应用程序代码对于当前的Node.js运行时而言太旧了。

The pump() method that Node.js provided wrote a readable to a writable stream using this syntax:

Node.js提供的pump()方法使用以下语法将可读写入可写流：

util.pump(readableStream, writableStream)

This method is now gone, deprecated for a long time and removed when Node.js 6.0 was released in April 2016.

该方法现已消失，不推荐使用很长时间，并于2016年4月发布Node.js 6.0时将其删除。

Luckily, it’s easy to fix this problem.

幸运的是，解决此问题很容易。

Replace the above syntax with:

将以上语法替换为：

const { pipeline } = require('stream')//...pipeline(readableStream, writableStream, () => {})

The third argument is a callback function that will be called when the pipeline is done.

第三个参数是在完成管道后将调用的回调函数。
