Gulp-autoprefixer throwing ReferenceError: Promise is not defined

Question

I try to make a gulp compile my sass then autoprefixit with gulp-autoprefixer but i'm getting an error.

var gulp = require('gulp'),
    sass = require('gulp-sass'),
    autoprefixer = require('gulp-autoprefixer');

gulp.task('test', function(){
    gulp.src('_sass/main.sass')
        .pipe(sass())
        .pipe(autoprefixer()) 
        .pipe(gulp.dest('./assets/css')); 
});

I'm trying to run this Gulpfile.js and i'm using :

"gulp": "~3.9.0",
"gulp-sass": "~2.0.4",
"gulp-autoprefixer": "~3.0.1",

and NPM version 1.3.10

When i run gulp test i get this :

/home/matei/Tests/test-4/node_modules/gulp-autoprefixer/node_modules/postcss/lib/lazy-result.js:152
        this.processing = new Promise(function (resolve, reject) {

I don't really know what i'm doing wrong. Is not working when i use sass or plain css. I think is something with my files.

Had the same issue. For me, updating node didn't work but adding this at the very beginning of my gulpfile did:

require('es6-promise').polyfill();
