angular - Angular 4，无法访问该网站

我在角度4中面临以下问题（在使用ng服务启动服务器之后）。我正在尝试点击网址http://localhost:4200/，但我收到的网页显示的消息为＆＃34;此网站无法到达＆＃34;。

下面是nodejs .npm和angular versions。

    PS E:\MyLearning\Angular4Examples\firstapp> node -v
    v8.11.1
    PS E:\MyLearning\Angular4Examples\firstapp> npm -v
    5.6.0
    PS E:\MyLearning\Angular4Examples\firstapp> ng -v
