gulp.series（）在运行多个任务时不起作用

I am trying to run multiple gulp tasks one after another in synchronised fashion

but i got the following error

TypeError: gulp.series is not a function

Code

gulp.task('default',function () {
    gulp.watch('resources/assets/js/components/*.js', function() {
        gulp.series('scripts','compress');
    });
}) 

If you want to use gulp.series and gulp.parallel you need gulp 4.0.

To get 4.+ which is technically in beta but has been around for a long time, use gulp v4

npm i gulp@4.0.0-alpha.2

Also you may install gulp version 4 using:

npm i gulpjs/gulp#4.0 --save-dev
