使用gulp uglify的未处理错误事件

Question

我使用gulp-uglify和gulp-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'))
})

然而，当我运行gulp scripts时，我得到了一个错误。这是错误堆栈跟踪：

          throw er; // Unhandled 'error' event
                ^

你知道哪里出问题了吗？Gulp版本为3.9.0，节点版本为0.12.7。

找到问题所在。它是由'./development/assets/js/lib/angular.min.js.map'引起的。uglify无法处理映射文件。
