我正在尝试根据http://angular.io上的快速入门设置 Angular 2。我已经按照指南中的描述完全复制了每个文件，但是当我运行npm start并打开浏览器选项卡时，在控制台中出现以下错误，我得到“正在加载...”:
Uncaught SyntaxError: Unexpected token < (program):1
__exec @ system.src.js:1374
Uncaught SyntaxError: Unexpected token < angular2-polyfills.js:138
Evaluating http://localhost:3000/app/boot
Error loading http://localhost:3000/app/boot
这是我的
app.component.ts:import {Component} from 'angular2/core';
@Component({
selector: 'my-app',
template: `<h1>My First Angular 2 App</h1>`
})
export class AppComponent {
}
我的
boot.ts:import {bootstrap} from 'angular2/platform/browser';
import {AppComponent} from './app.component';
bootstrap(AppComponent);
我的
index.html:<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Angular 2 Quick Start</title>
<script src="node_modules/es6-shim/es6-shim.js"></script>
<script src="node_modules/angular2/bundles/angular2-polyfills.js"></script>
<script src="node_modules/systemjs/dist/system.src.js"></script>

<script>
System.config({

defaultExtension: 'js'
}
});
System.import('app/boot')
.then(null, console.error.bind(console));
</script>
</head>
<body>
<my-app>Loading...</my-app>
</body>
</html>
我的
package.json:{
"name": "angular2-quickstart",
"version": "0.1.0",
"scripts": {
"tsc": "tsc",
"tsc:w": "tsc -w",
"lite": "lite-server",
"start": "concurrent \"npm run tsc:w\" \"npm run lite\" "
},
"license": "MIT",
"dependencies": {
"angular2": "2.0.0-beta.0",
"systemjs": "0.19.6",
"es6-promise": "^3.0.2",
"es6-shim": "^0.33.3",
"reflect-metadata": "0.1.2",

},
"devDependencies": {
"concurrently": "^1.0.0",
"lite-server": "^1.3.1",
"typescript": "^1.7.3"
}
}
最后是我的
tsconfig.json:{
"compilerOptions": {
"target": "ES5",
"module": "system",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"removeComments": false,
"noImplicitAny": false
},
"exclude": [
"node_modules"
]
}
在此先感谢您的帮助。
最佳答案
尝试更换它
System.config({
packages: {
format: 'register',
defaultExtension: 'js'
}
});
有了这个
System.config({
packages: {
app: { // must match your folder name
format: 'register',
defaultExtension: 'js'
}
}
});
我试图对他们的快速入门应用略有不同的文件夹结构，并遇到相同的问题。我发现“包装”对象上的属性名称必须与父文件夹匹配。
