TypeScript/TSLint:TSLint无法通过baseUrl识别根相对导入

Question

根据这个解决方案，我通过tsconfig.json中的baseUrl编译器选项使用根相对导入，但我遇到了一个问题，Atom IDE向我显示了如下错误：

Cannot find module 'core/nav-menu/nav-menu.component'.

导入看起来像(在src/app/core/nav-menu.module.ts中(：

import { NavMenuComponent } from 'core/nav-menu/nav-menu.component';

Atom中的TSLint找不到根相关的导入文件，但Angular编译器对它们没有问题。

我不确定我的tslint.json配置是否错误。。。在我在同一台机器上的另一个项目中，所有这些都如预期的那样工作，但我无法发现这个项目有什么不同，导致了这个问题。

附带说明一下，为什么baseUrl: "app"不是默认值？为什么文件相对导入看起来像是Angular/TypeScript开发的标准。这太疯狂了。

Answer 1

您的基本url错误：

您的tsconfig.json必须设置为："baseurl": "./"

你的tsconfig.app.ts中不需要baseurl，它应该被删除。

正如评论中所建议的那样，导入路径也应该更新。在导入路径前面添加"src/app"。

如果您的结构如下，并且您正在运行Angular 6:，则适用于此

* project
| - src
| | - app (with app files like app.modules.ts)
| | - tsconfig.app.json
| - tsconfig.json

也许你篡改了文件，试图找出问题所在。这也是新生成的Angular项目的标准配置。
