Question

我正在尝试使用Typescript和ASP.NET Core设置Angular2。这是package.json：

{
  "name": "testappuit",
  "version": "1.0.0",
  "license": "ISC",
  "dependencies": {
    "@angular/common": "2.0.0-rc.6",
    "@angular/compiler": "2.0.0-rc.6",
    "@angular/compiler-cli": "0.6.0",
    "@angular/core": "2.0.0-rc.6",
    "@angular/forms": "2.0.0-rc.6",
    "@angular/http": "2.0.0-rc.6",
    "@angular/platform-browser": "2.0.0-rc.6",
    "@angular/platform-browser-dynamic": "2.0.0-rc.6",
    "@angular/router": "3.0.0-rc.2",
    "@angular/upgrade": "2.0.0-rc.6",
    "core-js": "^2.4.1",
    "reflect-metadata": "^0.1.3",
    "rxjs": "5.0.0-beta.11",
    "systemjs": "0.19.27",
    "zone.js": "^0.6.17",
    "bootstrap": "^3.3.6"
  },
  "devDependencies": {
    "typescript": "^1.8.10",
    "typings":"^1.3.2"
  }
}

和tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false,
    "outDir": "../wwwroot/app"
  },
  "exclude": [
    "node_modules",
    "wwwroot"
  ]
}

和systemjs.config.js

(function (global) {
    System.config({
        paths: {
            'npm:': 'node_modules/'
        },
        map: {
            app: 'app',
            '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
            '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
            '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
            '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
            '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
            '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
            '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
            '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
            'rxjs': 'npm:rxjs',
            'angular2-in-memory-web-api': 'npm:angular2-in-memory-web-api',
        },
    packages: {
                app: {
                    main: './main.js',
                    defaultExtension: 'js'
                },
                rxjs: {
                    defaultExtension: 'js'
                },
                'angular2-in-memory-web-api': {
                    main: './index.js',
                    defaultExtension: 'js'
                }
            }
        });
    })(this);

和app.component.ts：

import { Component } from '@angular/core';
@Component({
    selector: 'my-app',
    template: '<h1>My First Angular 2 App</h1>'
})
export class AppComponent { }

app.module.ts：

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent }   from './app.component';
@NgModule({
    imports: [BrowserModule],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

和main.ts

/// <reference path="../../typings/globals/core-js/index.d.ts" />
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);

的index.html：

<html>
<head>
    <title>Angular 2 QuickStart</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="styles.css">
    <!-- 1. Load libraries -->
    <!-- Polyfill(s) for older browsers -->
    <script src="node_modules/core-js/client/shim.min.js"></script>
    <script src="node_modules/zone.js/dist/zone.js"></script>
    <script src="node_modules/reflect-metadata/Reflect.js"></script>
    <script src="node_modules/systemjs/dist/system.src.js"></script>
    <!-- 2. Configure SystemJS -->
    <script src="systemjs.config.js"></script>
    <script>
      System.import('app/main').catch(function(err){ console.error(err); });
    </script>
</head>
<!-- 3. Display the application -->
<body>
    <my-app>Loading...</my-app>
</body>
</html>

这是项目结构：

如果我尝试在浏览器中运行它，我会继续

未捕获的SyntaxError：意外的令牌未捕获的ReferenceError：系统未定义

帮我找出解决方案。

Answer 1

我相信这是因为你的systemjs.config.js不是你项目的根目录，试着用你的package.json将它移动到root。或者尝试在index.html I.E。

中直接映射到它

<script src="app/systemjs.config.js"></script>

或

<script src="wwwroot/app/systemjs.config.js"></script>

你甚至可能想要添加更高级别。还建议您将index.html放在项目的根目录下。如果您在运行应用程序时没有看到

Loading...

然后，这是一个提示，你的项目也没有看到你的index.html。

抱歉所有的编辑

另一个问题可能是您的项目无法找到应用程序＆＃39;因此，尝试将其映射到systemjs.config.js中，例如

map: {
        app: 'src/testappUI/wwwroot/app',
