How can I specify the gulpfile to use?

So I have two gulpfiles in this site I'm working on, one for the whole project which only watches and compiles sass and one inside a Foundation Emails project which is kept in a subdirectory in the project. When I try running any scripts or gulp tasks inside this Foundation subdirectory it runs the default task of the outer gulpfile. How can I make it so that when I'm in the subdirectory it only uses that gulpfile?

Outermost gulpfile:

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

gulp.task('default', function() {
return watch('ps_app/public/sass/*.scss')
gulp.task('sass', function() {
return gulp.src('ps_app/public/sass/*.scss')

Foundation Emails Subdirectory gulpfile:

import gulp from 'gulp';
import plugins from 'gulp-load-plugins';
import browser from 'browser-sync';
import rimraf from 'rimraf';
import panini from 'panini';
import yargs from 'yargs';
import lazypipe from 'lazypipe';
import inky from 'inky';
import fs from 'fs';
import siphon from 'siphon-media-query';
import path from 'path';
import merge from 'merge-stream';
import beep from 'beepbeep';
import colors from 'colors';

const $ = plugins();

// Look for the --production flag
const PRODUCTION = !!(yargs.argv.production);

// Declar var so that both AWS and Litmus task can use it.

// Build the "dist" folder by running all of the above tasks
gulp.series(clean, pages, sass, images, inline));

// Build emails, run the server, and watch for file changes
gulp.series('build', server, watch));

// Build emails, then send to litmus
gulp.series('build', creds, aws, litmus));

// Build emails, then zip
gulp.series('build', zip));

// Delete the "dist" folder
// This happens every time a build starts
function clean(done) {
rimraf('dist', done);

// Compile layouts, pages, and partials into flat HTML files
// Then parse using Inky templates
function pages() {
return gulp.src('src/pages/**/*.html')
root: 'src/pages',
layouts: 'src/layouts',
partials: 'src/partials',
helpers: 'src/helpers'

// Reset Panini's cache of layouts and partials
function resetPages(done) {

// Compile Sass into CSS
function sass() {
return gulp.src('src/assets/scss/app.scss')
.pipe($.if(!PRODUCTION, $.sourcemaps.init()))
includePaths: ['node_modules/foundation-emails/scss']
}).on('error', $.sass.logError))
.pipe($.if(!PRODUCTION, $.sourcemaps.write()))

// Copy and compress images
function images() {
return gulp.src('src/assets/img/**/*')

// Inline CSS and minify HTML
function inline() {
return gulp.src('dist/**/*.html')
.pipe($.if(PRODUCTION, inliner('dist/css/app.css')))

// Start a server with LiveReload to preview the site in
function server(done) {
server: 'dist'

// Watch for file changes
function watch() {
gulp.watch('src/pages/**/*.html').on('change', gulp.series(pages, inline, browser.reload));
gulp.watch(['src/layouts/**/*', 'src/partials/**/*']).on('change', gulp.series(resetPages, pages, inline, browser.reload));
gulp.watch(['../scss/**/*.scss', 'src/assets/scss/**/*.scss']).on('change', gulp.series(resetPages, sass, pages, inline, browser.reload));
gulp.watch('src/assets/img/**/*').on('change', gulp.series(images, browser.reload));

// Inlines CSS into HTML, adds media query CSS into the <style> tag of the email, and compresses the HTML
function inliner(css) {
var css = fs.readFileSync(css).toString();
var mqCss = siphon(css);

var pipe = lazypipe()
.pipe($.inlineCss, {
applyStyleTags: false,
removeStyleTags: false,
removeLinkTags: false
.pipe($.replace, '<!-- <style> -->', `<style>${mqCss}</style>`)
.pipe($.replace, '<link rel="stylesheet" type="text/css" href="css/app.css">', '')
.pipe($.htmlmin, {
collapseWhitespace: true,
minifyCSS: true

return pipe();

// Ensure creds for Litmus are at least there.
function creds(done) {
var configPath = './config.json';
try { CONFIG = JSON.parse(fs.readFileSync(configPath)); }
catch(e) {
console.log('[AWS]'.bold.red + ' Sorry, there was an issue locating your config.json. Please see README.md');

// Post images to AWS S3 so they are accessible to Litmus test
function aws() {
var publisher = !!CONFIG.aws ? $.awspublish.create(CONFIG.aws) : $.awspublish.create();
var headers = {
'Cache-Control': 'max-age=315360000, no-transform, public'

return gulp.src('./dist/assets/img/*')
// publisher will add Content-Length, Content-Type and headers specified above
// If not specified it will set x-amz-acl to public-read by default

// create a cache file to speed up consecutive uploads

// print upload updates to console

// Send email to Litmus for testing. If no AWS creds then do not replace img urls.
function litmus() {
var awsURL = !!CONFIG && !!CONFIG.aws && !!CONFIG.aws.url ? CONFIG.aws.url : false;

return gulp.src('dist/**/*.html')
.pipe($.if(!!awsURL, $.replace(/=('|")(\/?assets\/img)/g, "=$1"+ awsURL)))

// Copy and compress into Zip
function zip() {
var dist = 'dist';
var ext = '.html';

function getHtmlFiles(dir) {
return fs.readdirSync(dir)
.filter(function(file) {
var fileExt = path.join(dir, file);
var isHtml = path.extname(fileExt) == ext;
return fs.statSync(fileExt).isFile() && isHtml;

var htmlFiles = getHtmlFiles(dist);

var moveTasks = htmlFiles.map(function(file){
var sourcePath = path.join(dist, file);
var fileName = path.basename(sourcePath, ext);

var moveHTML = gulp.src(sourcePath)
.pipe($.rename(function (path) {
path.dirname = fileName;
return path;

var moveImages = gulp.src(sourcePath)
.pipe($.htmlSrc({ selector: 'img'}))
.pipe($.rename(function (path) {
path.dirname = fileName + '/assets/img';
return path;

return merge(moveHTML, moveImages)
.pipe($.zip(fileName+ '.zip'))

return merge(moveTasks);

The specific tasks I run are
npm start
npm run build
which do these tasks in my package.json in the same subdirectory as the Foundation Emails:

"scripts": {
"start": "gulp",
"build": "gulp --production",
"zip": "gulp zip --production",
"litmus": "gulp litmus --production"

Thank you for any help you can give.

You can use the --gulpfile CLI parameter to manually specify the gulpfile:

--gulpfile <gulpfile path> will manually set path of gulpfile. Useful if you have multiple gulpfiles. This will set the CWD to the gulpfile directory as well
