angular - ng-bootstrap 不工作如果 'ngb-xx' 是一个 Angular 组件，那么验证它是这个模块的一部分

Question

获取消息

If 'ngb-xx' is an Angular component, then verify that it is part of this module

对于我尝试的每个 Angular Bootstrap 组件

设置过程

npm install angular-cli
ng new project 
npm install 
npm install  --save bootstrap 
npm install --save @ng-bootstrap/ng-bootstrap

在 app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http' ;

import { NgbModule } from '@ng-bootstrap/ng-bootstrap' ;

import { AppComponent } from './app.component';
import { NgForm } from '@angular/forms/src/directives/ng_form';


@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    NgbModule.forRoot()
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

在 .angular-cli.json

  "styles": [
    "styles.css", 
    "../node_modules/bootstrap/dist/css/bootstrap.min.css"
  ],

甚至尝试添加 npm install --save jquery 和 .angular-cli.json

  "scripts": [ 
    "../node_modules/jquery/dist/jquery.js",
    "../node_modules/bootstrap/dist/js/bootstrap.min.js"
  ],

在 app.component.html 添加

  <ngb-tabset> 
      <ngb-tab title="test">
        <template ngbTabContent> 
            xxx ss
        </template>
      </ngb-tab>

      <ngb-tab title="test">
          <template ngbTabContent> 
              xxxs ss
          </template>
        </ngb-tab>
  </ngb-tabset>
<p>
  <ngb-alert [dismissible]="false">
    <strong>Warning!</strong> Better check yourself, you're not looking too good.
  </ngb-alert>
</p>

CSS似乎可以工作，但业力错误并且没有js

Failed: Template parse errors: 'ngb-tab' is not a known element:

1. If 'ngb-tab' is an Angular component, then verify that it is part of this module.

2. If 'ngb-tab' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.

("

仅加勒特

Failed: Template parse errors: Can't bind to 'dismissible' since it isn't a known property of 'ngb-alert'.

1. If 'ngb-alert' is an Angular component and it has 'dismissible' input, then verify that it is part of this module.

2. If 'ngb-alert' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.

3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component.

请帮忙谢谢

看起来问题似乎来自业力/ Jasmine 设置

这是我的 karma.conf.js

//Karma 配置文件，更多信息见链接
// https://karma-runner.github.io/1.0/config/configuration-file.html

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular/cli'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular/cli/plugins/karma')
    ],
    client:{
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    coverageIstanbulReporter: {
      reports: [ 'html', 'lcovonly' ],
      fixWebpackSourcePaths: true
    },
    angularCli: {
      environment: 'dev'
    },
    reporters: ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['Chrome'],
    singleRun: false
  });
};

问题在这里:

npm install angular-cli
ng new project 
npm install 
npm install  --save bootstrap 
npm install --save @ng-bootstrap/ng-bootstrap

创建项目后忘记进入目录

npm install angular-cli
ng new project 
cd 'project' // <-------------- Here , you missed this
npm install 
npm install  --save bootstrap 
npm install --save @ng-bootstrap/ng-bootstrap

我可以在这里找到的另一个问题是 <template ngbTabContent>
更改 <template ngbTabContent>至 <ng-template ngbTabContent>并且 </template>至 </ng-template> .
