Node.js fs.createWriteStream 未定义 function

Question

I am trying to write data to a text file in Node.js. When initializing the write stream I get the following error message:

Answer 1

Be sure you have included at the top of your node program

var fs = require('fs');

Also It looks like you spelled 'Stream' incorrectly

fs.createWriteSteam > fs.createWriteStream

Answer 2

Another issue that may come up is trying to get createWriteStream from 'fs/promises'. It doesn't exist on 'fs/promises'. (At least on NodeJS version 14);

My solution was to import both:

var fs = require('fs');
var fsPromises = require('fs/promises');
