javascript - 构建 Angular 8 项目时出现空白页面，但使用“ng serve”可以完美运行

Question

我的项目正在使用“ng serve”命令，但在构建时只显示一个空白屏幕。此消息显示在控制台中：

Angular 正在开发模式下运行。调用 enableProdMode() 以启用生产模式。

没有加载路由，模板中间只有一个空标签。

我尝试了 AOT 和 JIT。生产和发展模式。全部空白

我刚刚在这里发布了这个项目：https ://razesheydaei.ir

这是我的 angular.json 文件：

              "tsconfig.spec.json",
              "e2e/tsconfig.json"

            "exclude": ["**/node_modules/**"]
          }
        },
        "e2e": {

          }
        }
      }
    }
  },
  "defaultProject": "ui"
}

还有 tsconfig.json：

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "module": "esnext",
    "moduleResolution": "node",
    "importHelpers": true,
    "target": "es2015",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2018",
      "dom"
    ]
  },
  "angularCompilerOptions": {
    "fullTemplateTypeCheck": true,
    "strictInjectionParameters": true
  }
}

和路线：

const routes: Routes = [
  {
    path: '',
    component: MainComponent,
    canActivate: [AuthGuard],

    children: [
      {
        path: 'user',
        loadChildren: () => import('./systems/user/user.module').then(mod => mod.UserModule)
      },
      {
        path: 'usergroup',
        loadChildren: () => import('./systems/user-group/user-group.module').then(mod => mod.UserGroupModule)
      },
      {
        path: 'flight',
        loadChildren: () => import('./systems/flight/flight.module').then(mod => mod.FlightModule)
      }
    ]
  },
  {
    path: '',
    component: SimpleComponent,
    children: [
      {
        path: '',
        component: LoginComponent
      },
      {
        path: 'login',
        component: LoginComponent
      }
    ]
  },
  {
    path: '**',
    component: LoginComponent
  }
];

我认为问题出在您的应用服务器上

如果你使用 nginx 试试这个配置

      worker_processes  1;

      events {
          worker_connections  1024;
      }

      http {
          server {
              listen 80;
              server_name  localhost;
              access_log off;

              root   /usr/share/nginx/html;
              index  index.html index.htm;
              include /etc/nginx/mime.types;

              gzip on;
              gzip_min_length 1000;
              gzip_proxied expired no-cache no-store private auth;
              gzip_types text/plain text/css application/json application/javascript application/x-javascript text/xml application/xml application/xml+rss text/javascript;

              location / {
                  try_files $uri $uri/ /index.html;
              }
          }
      }

在这里尝试使用 docker 是 dockerfile

FROM nginx:alpine

COPY nginx.conf /etc/nginx/nginx.conf

WORKDIR /usr/share/nginx/html
COPY dist/out-tsc/ .
