Question

我正在尝试让ngx-bootstrap（首先是TooltipModule）在我的.net core 2.1 angular 6应用程序中工作（我已经从angular 5升级到了6）。我遵循了ngx-bootstrap:tooltip的指示。

所以我执行以下步骤：-

1. npm install ngx-bootstrap --save 

2. // RECOMMENDED (doesn't work with system.js)
   import { TooltipModule } from 'ngx-bootstrap/tooltip';
   // or
   import { TooltipModule } from 'ngx-bootstrap';

   @NgModule({
     imports: [TooltipModule.forRoot(),...]
   })
   export class AppModule(){}

3. <button type="button" class="btn btn-primary"
       tooltip="Vivamus sagittis lacus vel augue laoreet rutrum faucibus.">
     Simple demo
   </button>

然后，我启动应用程序，并在浏览器上显示“无法获取/”错误。如果我从AppModules Imports中删除了TooltipModule，则该应用程序将正常加载。

当我检查开发人员控制台时，它说：“无法加载资源：服务器以404（）localhost /：1状态响应”

我正在使用Angular CLI：6.1.1和Node：10.7.0，请帮忙。

这是我的angular.json文件：-

Answer 1

好的，所以我设法找出了问题所在。我真的很傻。我正在运行npm install ngx-bootstrap-保存在错误的文件夹中。所以我将其CD命名为my-app-folder / ClientApp的正确文件夹，运行命令，package.json显示ngx-bootstrap，而node_modules现在具有ngx-bootstrap文件夹，并且导入模块有效：)

Answer 2

尝试：

ng add @ng-bootstrap/schematics

更新package.json：

"@ng-bootstrap/schematics": "^2.0.0-alpha.1",
"@ng-bootstrap/ng-bootstrap": "^2.0.0-alpha.0",

更新app.module.ts（在导入中）：

NgbModule.forRoot()

更新angular.json（以样式显示）：

        {"input": "./node_modules/bootstrap/dist/css/bootstrap.css"}

.net核心angular 6应用ngx-bootstrap无法正常工作错误：“无法获取/”
