作为一个新手Angular程序员,我试图将之前的 Angular 2.0.0-beta17 web 应用程序升级到 Angular 2.3.0。现在我在加载/启动应用程序时遇到了问题。
我的设置如下:
出于解决方案目的,目前我复制了所有的 node_modules 到 web 目录中,因此不应该缺少任何文件。
我已经在Google和Stackoverflow上搜索了几个小时,但是没有找到解决这个问题的方法。你能告诉我如何解决吗?非常感谢您的帮助!如果需要,我可以提供代码库,请问您是否需要呢?

package.json
每次更改 package.json
后,我都会丢弃并重新构建模块文件夹,因此它是最新的。

index.html(仅脚本部分):
我根据我的文件/目录结构设置了路径。
<script type="text/javascript" src='/js/lib/es6-shim/es6-shim.min.js'></script>
<script type="text/javascript" src="/js/lib/rxjs/bundles/Rx.min.js"></script>
<script type="text/javascript" src="/js/lib/zone.js/dist/zone.min.js"></script>
<script type="text/javascript" src="/js/lib/reflect-metadata/Reflect.js"></script>
<script type="text/javascript" src='/js/lib/systemjs/dist/system.src.js'></script>
<script type="text/javascript">
System.config({
packages: {
js: {
format: 'register',
defaultExtension: 'js'
}
},
paths: {
'@angular/*': 'js/lib/@angular/*/index.js',
'rxjs/*': 'js/lib/rxjs/*.js'
}
});
System.import('js/boot').catch(function(err){ console.error(err); });
</script>
boot.ts(已由我的gulpfile成功转换为js)尝试在第1行加载angular-core。
import '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { Http, Response, Headers } from '@angular/http';
import { FeedbackFormComponent } from './feedback-form.component';
platformBrowserDynamic().bootstrapModule(FeedbackFormComponent);
在 System.import (index.html) 之前的所有内容 似乎 都已经准备就绪。 加载了 lib 文件,没有出现 404 等错误。但是我一直收到以下错误:

node_modules
。这样会破坏路径。 - Roman C
