Node.js 防止错误 destruct 崩溃 gulp watch

我正在运行gulp 3.6.2，下面的任务是通过在线示例设置的

gulp.task('watch', ['default'], function () {
  gulp.watch([
    'views/**/*.html',        
    'public/**/*.js',
    'public/**/*.css'        
  ], function (event) {
    return gulp.src(event.path)
      .pipe(refresh(lrserver));
  });

  gulp.watch(['./app/**/*.coffee'],['scripts']);
  gulp.watch('./app/**/*.scss',['scss']);
});

每当我的咖啡脚本中出现错误时，手表就会停止——显然不是我想要的.

As recommended elsewhere I tried this

gulp.watch(['./app/**/*.coffee'],['scripts']).on('error', swallowError);
gulp.watch('./app/**/*.scss',['scss']).on('error', swallowError);
function swallowError (error) { error.end(); }

但它似乎不起作用.

我做错了什么？

为了回应@Aperçu的回答，我修改了我的swallowError方法，并try 了以下方法:

gulp.task('scripts', function () {
  gulp.src('./app/script/*.coffee')
    .pipe(coffee({ bare: true }))
    .pipe(gulp.dest('./public/js'))
    .on('error', swallowError);
});

重新启动，然后在我的咖啡文件中创建了一个语法错误.同样的问题:
