在尝试进行Angular教程时,我遇到了很多试图执行路由器部分的问题。起初我根本无法进行编译,它说无法找到路由器,导致我尝试升级到3.0.0 alpha以及其他我甚至无法记住的潜在解决方案。最终我得到了它的编译,但是当我尝试查看页面时,我得到的只是默认的“正在加载...”文本以及JS控制台中的控制台错误:
<div class="grid-headers">
<div class="grid-column-date grid-header-item">Date</div>
<div class="grid-column-col1 grid-header-item">Col1</div>
<div class="grid-column-col2 grid-header-item">Col2</div>
<div class="grid-column-col3 grid-header-item">Col3</div>
</div>
<ul class="grid-content">
<li ng-repeat="item in vm.gridItems" class="grid-row">
<div class="grid-column-date grid-row-item"></div>
<div class="grid-column-col1 grid-row-item"></div>
<div class="grid-column-col2 grid-row-item"></div>
<div class="grid-column-col3 grid-row-item"></div>
</li>
</ul>
我的index.html看起来像这样:
localhost/:18 Error: Error: XHR error (404 Not Found) loading http://localhost:3000/router(…)(anonymous function) @ localhost/:18
http://localhost:3000/node_modules/@angular/router/router.umd.js Failed to load resource: the server responded with a status of 404 (Not Found)
我的package.json看起来像:
<html>
<head>
<base href="/">
<title>My lil' tour o' 'roes</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="styles.css">

我是网络开发的新手,不知道其他文件/信息会有什么帮助,但会尝试用人们建议的内容更新帖子。我在OS X(El Capitan 10.11.5)上运行,在Visual Studio Code中开发并使用Vivaldi(基于Chrome)作为我的Web浏览器。

Angular将所有模块移动到bundles
子目录(see the breaking changes for rc.2 here)。在system.config中,您需要将路由器包映射到该目录:
var packages = {
/* Other packages..*/
'@angular/router': { main: 'bundles/router.umd', defaultExtension: 'js' }
}
