Why am I getting gulp-changed error?

Question

My gulpfile is below -

'use strict';

//dependencies
var gulp = require('gulp');
var sass = require('gulp-sass');
var minifyCss = require('gulp-clean-css');
var uglify = require('gulp-uglify');
var rename = require('gulp-rename');
var changed = requrie('gulp-changed');

Error after runnning gulp. Error is for var changed = requrie('gulp-changed'); -

ReferenceError: requrie is not defined

    at Liftoff.handleArguments (/usr/lib/node_modules/gulp-

Gulp version - 3.9.1 React native version - 2.0.1 I have installed all the dependencies both globally and for the project alone.

Answer 1

there iss a spelling mistake

Replace this

var changed = requrie('gulp-changed');

by

var changed = require('gulp-changed');
