styles.76a1111….css:1 Failed to load resource: the server responded with a status of 404 (Not Found)
runtime.06daa30….js:1 Failed to load resource: the server responded with a status of 404 (Not Found)

Answer 1

您需要将<base href="/">更改为<base href="./">

Answer 2

尝试以下说明，

使用AppModule的路由器配置

RouterModule.forRoot(appRoutes, { useHash: true })
从index.html删除基本URL并在AppModule中动态添加

import { APP_BASE_HREF } from '@angular/common'; providers: [{ provide: APP_BASE_HREF, useValue: '/' }],

Answer 3

您无法直接从index.html文件夹打开dist。您必须使用某种反向代理服务器。

您可以使用Nginx。

修改以下配置并将其添加到您的nginx.conf文件中：

location /angular {
   alias "C:\\<Your Project Location>\\dist";   
   index index.html index.htm;
   try_files $uri $uri/ /index.html =404;
}

然后，您可以通过以下方式访问项目dist文件：
http://localhost/angular

您的错误也将得到解决。

假设您的angular.json文件已正确定义了baseHref和deployUrl。
示例：

{
  ...
  "projects": {
    "<Your project>": {
      ...
      "architect": {
        "build": {
          ...
          "options": {
            "baseHref": "/angular/",
            "deployUrl": "/angular/",
            ...
          }
        }
      }
    }
  }
}
