我正在使用gulp-uglifyandgulp-concat来缩小和连接我的 js 文件，如下所示：
gulp.task('scripts', function() {
gulp.src([
'./development/assets/js/lib/jquery-1.11.2.min.js',
'./development/assets/js/lib/foundation.min.js',
'./development/assets/js/lib/angular.min.js',
'./development/assets/js/lib/angular.min.js.map',
'./development/assets/js/lib/angular-ui-router.min.js',
'./development/assets/js/lib/angular-animate.js',
'./development/assets/js/lib/angular-sanitize.min.js',
'./development/assets/js/lib/loading-bar.min.js',
'./development/assets/js/lib/angular-sanitize.min.js',
'./development/assets/js/lib/toastr.min.js',
'./development/assets/js/lib/angular-datepicker.js',
'./development/assets/js/lib/angucomplete-alt.js',
'./development/assets/js/lib/d3.v3.min.js',
'./development/assets/js/lib/mm-foundation.min.js',
'./development/assets/js/lib/ng-text-truncate.js',
'./development/assets/js/lib/angular-lazy-loader.min.js',
'./development/assets/js/lib/jquery-jvectormap-2.0.3.min.js',
'./development/assets/js/lib/jquery-jvectormap-world-mill.js',
'./development/assets/js/lib/jquery.tagcanvas.min.js',
'./development/assets/js/lib/angular-touch.min.js',
'./development/assets/js/lib/slick.min.js',
'./development/assets/js/lib/angular-slick.min.js',
'./development/assets/js/lib/d3.tip.js',
'./development/assets/js/lib/angular-pageslide-directive.js',
'./development/assets/js/app.js',
'./development/assets/js/lib/upload.js',
'./development/assets/js/controllers/**/*.js',
'./development/assets/js/services/**/*.js',
'./development/assets/js/filters/**/*.js',
'./development/assets/js/directives/**/*.js'
])
.pipe(concat('production.js'))
.pipe(uglify())
.pipe(gulp.dest('./production/assets'))
})
但是，当我运行时gulp scripts出现错误。这是错误堆栈跟踪：
events.js:85
throw er; // Unhandled 'error' event

知道出了什么问题吗？Gulp 版本为 3.9.0，节点版本为 0.12.7。
