我认为这是WebStorm的问题,而不是核心Angular问题。
这是我按 Alt + Enter 时导入的方式,然后当我打开网页时,它为node_module
显示404。
import {Router} from "../../../../node_modules/@angular/router/src/router";
import {ActivatedRoute} from "../../../../node_modules/@angular/router/src/router_state";
之前它曾经像这样导入,这是对的:
import {Router, ActivatedRoute} from "@angular/router";
它过去常常工作,但现在它不会从system.config.js
中的映射文件导入。我不知道为什么会这样。我试图改变system.config.js
和tsconfig.json
中的差异。不知道它是否与此有关。
我的System.config.js:
/**
* System configuration for Angular samples
* Adjust as necessary for your application needs.
*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
// angular bundles

在.idea目录中的projectName.iml文件中,我有一行
<content url="file://$MODULE_DIR$/node_modules" />
这似乎对我造成了问题,将其删除并重新开始工作。

我遇到了同样的问题,并帮助我使用文件 - &gt;使高速缓存/重新启动无效并删除.idea中的文件(只需将其留空)。之后进口对我来说很好。
