Question

我是一个非常有角度的初学者。最近开始使用VS 2017和Angular-CLI。

面临两个麻烦。

接下来是当我执行应用程序时，它不反映更改，直到我运行NG build in命令。我从windows powershell执行命令。因此，一旦页面加载或执行之前，如果我运行 NG BUILD ，当页面显示其具有所有更改时。不明白为什么。

接下来是当我从控制台执行 NG SERVE 然后执行应用程序时，只显示标题栏文本。内容部分或正文中的任何内容都不是空的。所以为了让它再次显示，我需要打破应用程序然后 NG BUILD ，然后运行它就像以前一样显示页面。

这些是我的package.json

中的配置

Answer 1

按照与从角度安装到另一个文件夹中的“ ng serve”相同的过程进行。我也遇到了同样的问题，因此我在另一个文件夹中再次尝试了相同的过程，它可以工作。现在不再有空白页。

在控制台Visual Studio 2017中尝试NG SERVE时页面内容未加载Angular-CLI
