AssertionError [ERR_ASSERTION]: Task function must be specified
I am attempting to refactor some legacy code I wrote 2 years ago. A gulpfile.js file to be precise.
It seems like the problem is here:
// gulp.task('default', ['browserify', 'copy'], function() {
// return gulp.watch('src/**/*.*', ['browserify', 'copy']);
// });
I commented it out and replaced it with this:
gulp.task('default', gulp.series('browserify', 'copy'), function() {
return gulp.watch('src/**/*.*', ['browserify', 'copy']);
});
Not good enough. The whole file looks like this:
var gulp = require('gulp');
var browserify = require('browserify');
var reactify = require('reactify'); // Converts jsx to js
var source = require('vinyl-source-stream'); // Converts string to a stream
gulp.task('browserify', function() {
browserify('./src/js/main.js')
.transform('reactify')
.bundle()
.pipe(source('main.js'))
.pipe(gulp.dest('dist/js'));
});
gulp.task('copy', function() {
gulp.src('src/index.html').pipe(gulp.dest('dist'));
gulp.src('src/css/*.*').pipe(gulp.dest('dist/css'));
gulp.src('src/images/*.*').pipe(gulp.dest('dist/images'));
gulp.src('src/js/vendors/*.*').pipe(gulp.dest('dist/js'));
});
// gulp.task('default', ['browserify', 'copy'], function() {
// return gulp.watch('src/**/*.*', ['browserify', 'copy']);
// });
gulp.task('default', gulp.series('browserify', 'copy'), function() {
return gulp.watch('src/**/*.*', ['browserify', 'copy']);
});
I have read through some of the getting started documentation, but what I have read thus far has not helped me refactor this.

This issue faced me because of the version of gulp I installed using npm i gulp
to solve this quickly, downgrade to that gulp version you used before 2 years and everything will work fine.

With Gulp 4.0 the way you run tasks in series has got changed. You can read and get what you want using below link
