JS_Parse_Error uglify Angular 2组件

Question

我开始使用Angular 2.这是我的Angular 2组件：

import {Component} from 'angular2/core';

@Component({
    selector: 'my-app',
    template: '<h1>My First Angular 2 App</h1>'
})
export class AppComponent { };

在Javascript文件中翻译为：

System.register(['angular2/core'], function(exports_1, context_1) {
    "use strict";
    var __moduleName = context_1 && context_1.id;
    var __decorate = (this && this.__decorate) || function (decorators, target, key, desc) {
        var c = arguments.length, r = c < 3 ? target : desc === null ? desc = Object.getOwnPropertyDescriptor(target, key) : desc, d;
        if (typeof Reflect === "object" && typeof Reflect.decorate === "function") r = Reflect.decorate(decorators, target, key, desc);
        else for (var i = decorators.length - 1; i >= 0; i--) if (d = decorators[i]) r = (c < 3 ? d(r) : c > 3 ? d(target, key, r) : d(target, key)) || r;
        return c > 3 && r && Object.defineProperty(target, key, r), r;
    };
    var __metadata = (this && this.__metadata) || function (k, v) {
        if (typeof Reflect === "object" && typeof Reflect.metadata === "function") return Reflect.metadata(k, v);
    };
    var core_1;
    var AppComponent;
    return {
        setters:[
            function (core_1_1) {
                core_1 = core_1_1;
            }],
        execute: function() {
            let AppComponent = class AppComponent {
            };
            AppComponent = __decorate([
                core_1.Component({
                    selector: 'my-app',
                    template: '<h1>My First Angular 2 App</h1>'
                }), 
                __metadata('design:paramtypes', [])
            ], AppComponent);
            exports_1("AppComponent", AppComponent);
        }
    }
});
//# sourceMappingURL=app.component.js.map

当我尝试使用此任务进行uglify时：

gulp.task('uglifyAppLibs', function (done) {
    gulp.src('./wwwroot/app/app.component.js')
    .pipe(gp_uglify())
    .pipe(gp_rename({
        suffix: '.min'
    }))
    .pipe(gulp.dest("./wwwroot/app"));
});

我收到此错误：

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

我在这里缺少什么？ ts文件到JS的转换是由Visual Studio编辑器自动完成的，所以它必须是正确的。

我的Gulp和NodeJS版本都是今天最新下载的。
