Gulp：与管道工的错误消息和通知

Question

In this example , it states you can use Gulp-Plumber and Gulp-Notify to display a message and sound each time there is an error. Gulp-Plumber will ensure that Gulp watch will continue to run.

However, when I try it, I keep on getting this error message, which causes Gulp to stop:

events.js:72
        throw er; // Unhandled 'error' event

Here is my code:

var gulp            = require('gulp'),
    sass            = require('gulp-ruby-sass'),
    jshint          = require('gulp-jshint'),
    uglify          = require('gulp-uglify'),
    rename          = require('gulp-rename'),
    concat          = require('gulp-concat'),
    notify          = require('gulp-notify'),
    plumber         = require('gulp-plumber'),



  var onError = function(err) {
        notify.onError({
                    title:    "Gulp",
                    subtitle: "Failure!",
                    message:  "Error: <%= error.message %>",
                    sound:    "Beep"
                })(err);

        this.emit('end');
         };


//Scripts Task
gulp.task('scripts', function() {
    gulp.src('frontend/build/js/*.js')
    .pipe(jshint('.jshintrc'))
    .pipe(jshint.reporter('default'))
    .pipe(concat('main.js'))
    .pipe(gulp.dest('frontend/dist/js'))
    .pipe(rename({suffix: '.min'}))
    .pipe(uglify())
    .pipe(gulp.dest('frontend/dist/scripts'))
       .pipe(notify({ 
           sound: "Frog"
    }));
});


//Styles Task
gulp.task('styles', function() { 
    return sass('frontend/build/scss/', {style: 'expanded'})
    .pipe(plumber({errorHandler: onError}))
    .pipe(gulp.dest('frontend/dist/css/'))
    .pipe(rename({suffix: '.min'}))
    .pipe(gulp.dest('dist/styles'))
    .pipe(notify({ // Add gulpif here
           sound: "Pop"
   }));

});

The only difference between my code and the example is that I have moved onError as a global function so it can be used in both the scripts and styles task. However, even if I move it back inside the styles function, the same error message occurs.

(the code I have posted is abbreviated, the full code can be found here )

Also, is there a way to hide the notification message on success so I just get the sound? Thanks!

您可能现在已经知道了这一点，但是在完整的代码中，onError函数的作用范围是您的样式任务，您也没有在脚本任务的任何地方使用管道工。
