使用angular2的系统in中的错误-高图

Question

在使用RC5配置angular2-高级图表时，我得到以下错误

产品:15错误: TypeError:无法读取属性'type‘of null(…)(匿名函数)@ product:15ZoneDelegate.invoke @ zone.js:332Zone.run @zone.js:225(匿名函数)@ zone.js:586ZoneDelegate.invokeTask @ zone.js:365Zone.runTask @ zone.js:265drainMicroTaskQueue @ zone.js:491ZoneTask.invoke @ zone.js:435

我的系统is如下

/**
 * System configuration for Angular 2 samples
 * Adjust as necessary for your application needs.
 */
(function(global) {
  // map tells the System loader where to look for things
  var map = {
    'app':                        'app', // 'dist',
    '@angular':                   'node_modules/@angular',
    'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
    'rxjs':                       'node_modules/rxjs',
    'angular2-highcharts':        'node_modules/angular2-highcharts/dist',
    'highcharts/highstock.src':   'node_modules/highcharts/highstock.js'
  };
  // packages tells the System loader how to load when no filename and/or no extension
  var packages = {
    'app':                        { main: 'main.js',  defaultExtension: 'js' },
    'rxjs':                       { defaultExtension: 'js' },
    'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' },
    'angular2-highcharts' :       { main: 'index', defaultExtension: 'js' }
  };
  var ngPackageNames = [
    'common',
    'compiler',
    'core',
    'forms',
    'http',
    'platform-browser',
    'platform-browser-dynamic',
    'router',
    'router-deprecated',
    'upgrade',
  ];
  // Individual files (~300 requests):
  function packIndex(pkgName) {
    packages['@angular/'+pkgName] = { main: 'index.js', defaultExtension: 'js' };
  }
  // Bundled (~40 requests):
  function packUmd(pkgName) {
    packages['@angular/'+pkgName] = { main: '/bundles/' + pkgName + '.umd.js', defaultExtension: 'js' };
  }
  // Most environments should use UMD; some (Karma) need the individual index files
  var setPackageConfig = System.packageWithIndex ? packIndex : packUmd;
  // Add package entries for angular packages
  ngPackageNames.forEach(setPackageConfig);
  var config = {
    map: map,
    packages: packages
  };
  System.config(config);
})(this);

这是我的app.module.ts

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule }    from '@angular/forms';
import { routing }       from './app.routing';
import { AppComponent }  from './app.component';
import { ProductDetail } from './detail.component';
import { CHART_DIRECTIVES } from 'angular2-highcharts';

@NgModule({
    imports:      [ BrowserModule, routing,FormsModule , CHART_DIRECTIVES],
    declarations: [ AppComponent,Detail ],
    exports:[Detail],
    bootstrap:    [ AppComponent ]
})
export class AppModule { }

Answer 1

您正在导入导入数组中的CHART_DIRECTIVES。imports数组专门用于导入模块，而不是其他任何东西。

因此，要么需要等待Angular2 -高级图表将它们的指令打包到Angular2 RC5模块中，然后只需导入该模块，要么现在需要将CHART_DIRECTIVES移动到“声明”数组中。
