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

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

10

我正在使用根相对导入，通过在 tsconfig.json 中使用 baseUrl 编译器选项，根据这个解决方案，但我遇到了一个问题，Atom IDE 显示了类似以下的错误提示信息：

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

导入的代码看起来像这样（在 src/app/core/nav-menu.module.ts 中）：

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

Atom中的TSLint无法找到根相关的导入文件，但Angular编译器没有问题。

我不确定我的tslint.json配置有什么问题...在我这台机器上的另一个项目中，所有这些都按预期工作，但我找不出这个项目与其他项目的区别，导致了这个问题。

顺便问一下，为什么baseUrl: "app"不是默认设置？为什么文件相关的导入似乎是Angular/TypeScript开发的标准？这太疯狂了。

在你的项目中，这个组件的引用在哪里 Cannot find module 'core/nav-menu/nav-menu.component.. 分享一下代码。 - eduPeeth

好的，我编辑了一个导入示例。每个根相对导入都会出现相同的错误。 - BBaysinger

你尝试设置 rootDirs 设置了吗？那可能会有所帮助。 - David

这不是tslint的问题。 - Aluan Haddad

您的基础URL不正确：

您的tsconfig.json必须设置为： "baseurl": "./"

您的tsconfig.app.ts中不需要baseurl，应将其删除。

如评论中建议的那样，导入路径也应进行更新。在导入路径前面添加“src / app”。

如果您的结构如下，并且正在运行Angular 6，则适用此方法：

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

也许您在尝试找出问题时篡改了文件。这也是新生成的Angular项目的标准配置。
