Angular2教程(英雄之旅) : 找不到“ Angular2-in-memory-web-api”模块
我一直在跟踪 教程。在 Http 章节中更改 app/maint.ts之后，我通过命令行启动应用程序时出现了错误:
App/main.ts (5,51) : 错误 TS2307: 无法找到模块‘ angular2-in-memory-web-api’。
(Visual Studio Code 在 main.ts 中给出了相同的错误——红色波浪形下划线。)
这是我的 systemjs.config.js:
/**
* 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'
};
// 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': { defaultExtension: 'js' },
};
var ngPackageNames = [
'common',
'compiler',
'core',
'http',
'platform-browser',
'platform-browser-dynamic',
'router',
'router-deprecated',
'upgrade',
];
// Add package entries for angular packages
ngPackageNames.forEach(function(pkgName) {
packages['@angular/'+pkgName] = { main: pkgName + '.umd.js', defaultExtension: 'js' };
});
var config = {
map: map,
packages: packages
}
System.config(config);
})(this);
这是我的 app/main.ts:
// Imports for loading & configuring the in-memory web api
import { provide } from '@angular/core';
import { XHRBackend } from '@angular/http';
import { InMemoryBackendService, SEED_DATA } from 'angular2-in-memory-web-api';
import { InMemoryDataService } from './in-memory-data.service';
// The usual bootstrapping imports
import { bootstrap } from '@angular/platform-browser-dynamic';
import { HTTP_PROVIDERS } from '@angular/http';
import { AppComponent } from './app.component';
bootstrap(AppComponent, [
HTTP_PROVIDERS,
provide(XHRBackend, { useClass: InMemoryBackendService }), // in-mem server
provide(SEED_DATA, { useClass: InMemoryDataService }) // in-mem server data
]);
