我开始学习Angular 2。这是我的角度2组件：

import {Component} from 'angular2/core';

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

我错过了什么？ts文件到JS的转换由VisualStudio编辑器自动完成，因此必须正确

我的Gulp和NodeJS版本都是今天下载的最新版本。

你使用的是哪个版本的uglify js和Gulp uglify？它适用于我的版本：uglify js（2.6.2）和Gulp uglify（1.5.3）。我在Gulp uglify（1.5.3）上遇到了同样的错误。此外，我不断删除组件以简化它，我发现根错误源于类声明。我只需要一个空类，它就会抛出这个错误。 
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"));
});
