Angular2教程(英雄之旅)：找不到模块'angular2-in-memory-web-api‘
我一直在关注Tutorial。在Http章节中更改app/maint.ts后，通过命令行启动应用程序时出现错误：
app/main.ts(5,51)：错误TS2307:找不到模块'angular2-in-memory-web-api‘。
(Visual Studio代码在main.ts中给出了同样的错误-红色的波浪形下划线。)
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

对我来说，唯一的解决方案是将angular2-in-memory-web-api升级到0.0.10。
在package.json集合中
'angular2-in-memory-web-api': '0.0.10'在dependecies块和systemjs.config.js集合中
'angular2-in-memory-web-api': { main: 'index.js', defaultExtension: 'js' }在packages对象中。

对于使用当前CLI工具创建的项目，我通过安装
npm install angular-in-memory-web-api --save，然后执行导入为
import { InMemoryWebApiModule } from 'angular-in-memory-web-api/in-memory-web-api.module';My package.json

以下是对我有效的方法：
我注意到package.json有以下版本：
"angular2-in-memory-web-api"："0.0.20“
注意名称中的"2“。
然而，当引用InMemoryWebApiModule时，它使用的是'angular- in -memory-web-api‘，名称中没有2。所以我添加了它，它解决了这个问题：
从‘angular2-in-memory-web-api’导入{ InMemoryWebApiModule }；
注释：我在https://github.com/angular/in-memory-web-api的通知部分找到了这个
从v.0.1.0开始，npm包从angular2-in-memory-
-api重命名为当前名称angular2-in-memory-web-api。0.0.21之后的所有版本都以此名称发布。确保更新您的package.json和import语句。
