What causes the ReferenceError: reqire is not defined error in gulp 4?

Question

JavaScript

Already killed half a day on all sorts of errors.
Googled, read something on the github, but I never found a solution.
Looks like I have very little understanding of what I'm dealing with.

gulpfile.js

'use strict';

const gulp = require('gulp');
const pug = require('gulp-pug');
const sass = reqire('gulp-sass');

const html = () => {
  return gulp.src('./pages/index.pug')
    .pipe(pug({
      pretty: true
    }))
    .pipe(gulp.dest('./build'))
}

const style = () => {
  return gulp.src('./src/style/style.scss')
    .pipe(sass())
    .pipe(gulp.dest('./build/css'))
}

exports.html = html;
exports.style = style;

exports.default = gulp.series(html, style);

package.json

{
  "name": "pug-starter",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "gulp": "^4.0.2",
    "gulp-pug": "^4.0.1",
    "gulp-sass": "^4.1.0"
  }
}
