how to force gulp run the gulpfile.babel.js instead of gulpfile.js (both are in same directory)? [duplicate]

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')
.pipe(sass())
.pipe(autoprefixer())
.pipe(gulp.dest('ps_app/public/css/custom'));
});
gulp.task('sass', function() {
return gulp.src('ps_app/public/sass/*.scss')
.pipe(sass())
.pipe(autoprefixer())
.pipe(gulp.dest('ps_app/public/css/custom'));
});

The specific tasks I run are npm start and 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

Gulp - output files not created

Below is a gulp task that has been created to compile angular2 tests written in typescript.
var path = require('path');
var gulp = require('gulp');
var conf = require('./conf');
var debug = require('gulp-debug');
var browserSync = require('browser-sync');
var $ = require('gulp-load-plugins')();
var typescript = require('typescript');
var tsTestProject = $.typescript.createProject({
target: 'es5',
sortOutput: true,
typescript: typescript,
experimentalDecorators: true
});
gulp.task('scripts-test', [], function () {
var gulpStream = gulp.src([
path.join(conf.paths.src, '/app/references.test.ts'),
path.join(conf.paths.src, '/app/**/*.spec.ts')
])
.pipe(debug())
.pipe($.sourcemaps.init())
.pipe($.typescript(tsTestProject)).on('error', conf.errorHandler('TypeScript'))
.pipe($.sourcemaps.write())
.pipe(gulp.dest('tmptest'))
.pipe(browserSync.reload({ stream: true }))
.pipe($.size());
return gulpStream;
});
Here's the log related to the task.
[20:47:45] Starting 'scripts-test'...
[20:50:18] TypeScript: emit succeeded (with errors)
[20:50:18] Finished 'scripts-test' after 2.53 min
Yet no output files (typescripts compiled into js) are created to a tmptest folder as given in the task. gulp-debug shows that all the files given in gulp.src are acquired to the stream. Any idea as to why this is happening?

Update: Errors with postCSS and Babel in Gulpfile

Goal
I'm updating my old gulpfile.js, which used to be mainly for compiling my Sass into CSS, but now I'm trying to get Gulp to do the following:
Sync browser, whip up localhost server - DONE
Compile Sass => CSS - DONE
Show any JavaScript errors with JSHint - DONE
Compile ES6 => ES6 with Babel (WORKING ON)
Minify all assets (WORKING ON)
Show project file size - DONE
Deploy index.html, style.css and images to S3 (WORKING ON)
Watch files, reload browser when .scss or .html changes - DONE
Problem
Trying to minify my Javascript and also create a scripts.min.js
file, it keeps adding the suffix min to every new minified JavaScript
file.
Folder structure
index.html
gulpfile.js
package.json
.aws.json
.csscomb.json
.gitignore

style.css

Hi i can't solve all your problems but I had also a similar issue with the babel and ES6 fat arrow functions (using babelify and browserify). To solve the problem try to pass:
stage: 0
to your babel.js gulp plugin. If error will still occurs then try to pass also:
experimental: true
For more information please have a look "experimental" section on babel.js site.

How to debug Express app launched by nodemon via Gulpfile in WebStorm 10?

How can I start debugging this application in Webstorm? I've tried 'Edit Configuration' panel, setting up NodeJS configuration and Gulpfile configuration, but still no luck.
I just don't understand how to actually implement this kind of debug process.
Any help would be appreciated. Thanks.

Turns out you have to set bin/www in JavaScript file setting and everything will be working as supposed to.
