我有一个使用Angular 4中的新路由器在本地制作的应用程序，但路由在Plunker中无法使用，相反，你必须使用旧的不推荐使用的路由器，才能使路由在Plunk中正常工作。我正在将我的应用程序从本地机器移植到Plunker进行演示，除了路由之外，一切都很好。这是我在控制台上得到的错误：
错误：(SystemJS)类型错误：router_depleted_1.RouteConfig不是一个函数
不知道怎么了。有人能帮忙吗？。以下是实现弃用路由器的文件：
SystemJS配置文件
var angularVersion;
if(window.AngularVersionForThisPlunker === 'latest'){
angularVersion = ''; //picks up latest
}
else {
angularVersion = '@' + window.AngularVersionForThisPlunker;
}

以下是Plunker，可以看到问题：
DEMO应用程序Plunker
查看src/main.ts，然后查看src/app.component.ts
基本上base href在路由、中起着至关重要的作用
当我们在Plunker中运行应用程序时，我们需要像下面这样设置基本href，以便它正确设置
<script>document.write('<base href="' + document.location + '" />');</script>
我已经更新了您的Plunker以解决问题，
