Question

我在ng2-slider项目中无法使用Angular 2 CLI。有关详细信息，请参阅以下屏幕截图。

错误：

在angular-cli.json

{
  "project": {
    "version": "1.0.0-beta.15",
    "name": "testbed-app"
  },
  "apps": [
    {
      "root": "src",
      "outDir": "dist",
      "assets": "assets",

        "../node_modules/primeng/resources/primeng.min.css",
        "../node_modules/font-awesome/css/font-awesome.css",
        "../node_modules/angular2-calendar/scss/angular2-calendar.scss",
        "styles.css"
      ],
      "scripts": [
        "../node_modules/jquery/dist/jquery.js",
        "../node_modules/bootstrap/dist/js/bootstrap.js",
        "../node_modules/tether/dist/js/tether.js",

        "../node_modules/angular2-calendar/dist/umd/angular2-calendar.js",
        "../node_modules/ng2-slider-component/ng2-slider.component.js",
        "../node_modules/ng2-slideable-directive/slideable.directive.js",
        "../node_modules/ng2-styled-directive/ng2-styled.directive.js"

      ],
      "environments": {
        "source": "environments/environment.ts",
        "dev": "environments/environment.ts",
        "prod": "environments/environment.prod.ts"

    }
  ],
  "addons": [
    "../node_modules/font-awesome/fonts/*.+(otf|eot|svg|ttf|woff|woff2)"
  ],
  "packages": [],
  "e2e": {
    "protractor": {
      "config": "./protractor.conf.js"
    }
  },
  "test": {
    "karma": {
      "config": "./karma.conf.js"
    }
  },
  "defaults": {
    "styleExt": "css",
    "prefixInterfaces": false
  }
}

然后在package.json

{
  "name": "testbed-app",
  "version": "0.0.0",
  "license": "MIT",
  "angular-cli": {},
  "scripts": {
    "start": "ng serve",

    "@angular/platform-browser": "2.0.0",
    "@angular/platform-browser-dynamic": "2.0.0",
    "@angular/router": "3.0.0",
    "angular2-calendar": "^0.3.3",

    "ng2-styled-directive": "^1.0.5",
    "primeng": "^1.0.0-beta.17",
    "primeui": "^4.1.15",
    "rxjs": "5.0.0-beta.12",
    "tether": "^1.3.7",
    "ts-helpers": "^1.1.1",
    "zone.js": "^0.6.23"
  },
  "devDependencies": {
    "@types/jasmine": "^2.2.30",
    "angular-cli": "1.0.0-beta.15",
    "codelyzer": "~0.0.26",

    "ts-node": "1.2.1",
    "tslint": "3.13.0",
    "typescript": "2.0.2"
  }
}

然后在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 { routing } from './app.routes';

import { AppComponent } from './app.component';
import { HeaderComponent } from './template/header/header.component';
import { ConfigurationComponent } from './view/configuration/configuration.component'; 
import { Ng2SliderComponent } from "ng2-slider-component/ng2-slider.component";

@NgModule({
  declarations: [
    AppComponent,
    HeaderComponent,
    ConfigurationComponent,
    Ng2SliderComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    routing    
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

然后在configration.component.ts

import { Component, OnInit } from '@angular/core';


@Component({
  selector: 'app-configuration',
  templateUrl: './configuration.component.html',
  styleUrls: ['./configuration.component.css']
})
export class ConfigurationComponent implements OnInit {

  constructor() { }

  ngOnInit() {
  }
  plainValueChanged(event, container:any) {
      var el = this.getElement(container);
      //el.innerText = event.startValue;
  }

  getElement(data){
      if (typeof(data)=='string') {
          return document.getElementById(data);
      }
      if (typeof(data)=='object' && data instanceof Element) {
          return data;
      }
      return null;
  }
}

Answer 1

ng2-slider-component断开，不再维护。目前有27个未决问题，其中许多是6个月或更长时间。我知道这不是你想要的答案......：）

Answer 2

在app.module.ts试试：

import { Ng2SliderComponent } from 'ng2-slider-component/ng2-slider.component';
import { SlideAbleDirective } from 'ng2-slideable-directive/slideable.directive';
import { Ng2StyledDirective } from 'ng2-styled-directive/ng2-styled.directive';

@NgModule({
  declarations: [
    SlideAbleDirective,
    Ng2StyledDirective,
    Ng2SliderComponent
  ],
  exports: [
    Ng2SliderComponent,
    Ng2StyledDirective
  ]
})

我正在使用systemjs.config.js，现在它正在为我工作。

对于那些使用systemjs.config.js的人：

System.config({
    paths: {
      'ng2-slider-component': 'node_modules/ng2-slider-component/',
      'ng2-slideable-directive': 'node_modules/ng2-slideable-directive/',
      'ng2-styled-directive': 'node_modules/ng2-styled-directive/',
    },
    packages: {
      'ng2-slider-component': {
        main: './ng2-slider.component.system.js',
        defaultExtension: 'system.js'
      },
      'ng2-slideable-directive': {
        main: './slideable.directive.js',
        defaultExtension: 'js'
      },
      'ng2-styled-directive': {
        main: './ng2-styled.directive.js',
        defaultExtension: 'js'
      }
    }
  });

ng2-slider-component + angular 2 final + angular cli
