Angular 4路由怪异的行为:除非在页面刷新上，否则不要渲染儿童模块

我一直在寻找这种怪异行为的解决方案。

Angular 4控制台或JavaScript控制台中没有错误
- 使用角CLI（Angular 4）

我使用角路由器的行为极为奇怪。我正在尝试从父苹果模块加载具有自己的模块的子路由。该路线在/产品

在/产品模块（products.module.ts）：我有3个路线：

/products/概述
/products/intro [重定向到/products]
/products/product/：产品

产品模块应该在Global AppModule的Navbar下具有自己的Navbar，该Navbar在products.component.component.html组件模板中的路由器范围上方。

主要问题：当我加载页面（不使用Angular Routerlink）时

两个Navbars都是可见的
加载的页面（EX/INTRO）可见NAVBAR，但子组件（Introcomponent）是 not 可见
但是，当我导航到/产品模块路由中的任何其他子程序时（ex/概述或/product/：product）：它的呈现不错。因此，在整页上加载的任何路线都不可见。

最奇怪的部分：当我将页面（刷新）加载到不是/products（ex/home）的路由上时，然后使用主纳维尔键导航到/产品：ul>

Navbar是看不到 ????????

可见的子组件（ex/intro组件）

这在过去几天里一直引起了我的大量地狱。

现在，一些代码：

app.module.ts [main AppModule]

    declarations: [
        AppComponent,
        HomeComponent,

这是我在Stackoverflow上的第一个"寻求帮助"帖子，所以让我知道我是否可以改进。

我试图研究各种形式和教程，并引用了Angular Doc进行路由

编辑：添加一些图片以进行更多澄清

主页：http：//prntscr.com/gskex5

products [/products/intro]（导航到使用Routerlink）：http：//prntscr.com/gskf2h（丢失了产品Navbar）在刷新中，纳维托变得可见，但介绍组件消失了：http：//prntscr.com/gskfaq

但是，当我单击产品导航中的另一个组件时，它可以正常工作：http：//prntscr.com/gskfhf

如果我刷新，则组件消失了，剩下NAV：http：//prntscr.com/gskfna现在，无论出于何种原因，如果我回到介绍，它都可以正常工作：http：//prntscr.com/gskfra

基本上，当页面最初加载时加载的任何路由，都有问题[不可见组件]。如果最初加载的路线不是/产品；产品Navbar不可见。

在这种相当奇怪的情况下，我能够通过使用Angular-cli生成新的Angular 4应用程序来解决这种奇怪的行为： ng new new

我猜这与我正在运行的Angular版本有关。

对于我的新项目， @angular 版本设置为**^4.0.0*。

在旧项目中，版本设置为4.3.1

我猜想这与v4.3.1的错误文件中的一个更改有关：

路由器：candeactivate守卫应从下到顶部（1AC78BF），关闭＃15657

路由器：应在配置时导航到同一URL 更改（4340BEA），关闭＃15535

路由器：应运行解析器同时（EC89F37），关闭＃14279

路由器：终端自定义匹配器（5D275E9）中的路线
