Gulp only refreshes once on PHP file update, not at all on CSS changes

[sittingpilgrim]

Working in a WAMP environment (Windows 10, PHP 7.1, Node v8.11.3, Gulp v2.0.1); running the fictional university lesson, section 7; the setup worked fine, but after the automatic reload after a PHP worked only once. Fixed this by added a done(); command after reload:
gulp.watch('./**/*.php', function() { browserSync.reload(); done(); });
See https://stackoverflow.com/questions/29801070/gulp-browser-sync-only-works-once
To fix the CSS I added a semi-colon after the cb() command in the waitforscripts task:
gulp.task('waitForScripts', gulp.series('scripts', function(cb) { browserSync.reload(); cb(); }))

Hello if you are using Local then in your settings file your themeLocation should be like this './wp-content/themes/fictional-university-theme/'
You dont need the /app/ in the front
Happy coding!

@sittingpilgrim I added done() like you suggested. Live reload works, but now I get a reference error in the console:

[14:00:15] Starting '<anonymous>'...
[14:00:15] '<anonymous>' errored after 6.92 ms
[14:00:15] ReferenceError: done is not defined

    at processTicksAndRejections (internal/process/task_queues.js:79:9)

I figured changing the code to gulp.watch('./**/*.php', function(done) { browserSync.reload(); done(); }); would fix the error, but then the live reload stops working again.

(to be clear, everything works, I just wanted to document this weird behavior here for future readers)

add callback function inside gulp.watch

gulp.watch('./**/*.php', function(done) {
    browserSync.reload();
    done();
  });
