Angular 10 : Import using module alias not resolved/Path Mapping not recognised in VSCode

Question

因此，我将 Angular 8.2(项目模板)中的项目更新到版本 10，并按照 https://update.angular.io/ 中的说明进行操作。一切都很好，但是当实现路径映射时，痛苦开始了，我到处都是这个错误:

Cannot find module '@environments/environment' or its corresponding type declarations.ts(2307)

此错误适用于 @环境 和 @模块 ，在路径中声明，其他没有显示任何错误，因为它们没有被使用。
现在，使用 时项目正在正确构建构建 ，没试过 ng build --prod ，没有出现错误，但 Visual Studio 代码 (v1.46.1) 正在向我展示有错误的导入，这就是我有:
src/tsconfig.json

{
  "files": [],
  "references": [
    {
      "path": "./tsconfig.app.json"
    },
    {
      "path": "./e2e/tsconfig.json"
    }
  ]
}

src/tsconfig.app.json

{
  "extends": "./tsconfig.base.json",
  "compilerOptions": {
    "outDir": "./lw/app",
    "types": []
  },
  "files": ["src/main.ts", "src/polyfills.ts"],
  "include": ["src/**/*.d.ts"],
  "exclude": ["src/test.ts", "src/**/*.spec.ts"]
}

src/tsconfig.base.json

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "src",
    "outDir": "./dist/lw",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "module": "es2020",
    "moduleResolution": "node",
    "importHelpers": true,
    "target": "es2015",
    "emitDecoratorMetadata": true,
    "noImplicitAny": false,
    "typeRoots": ["node_modules/@types"],
    "lib": ["es2018", "dom"],
    "paths": {
      "@angular/*": ["./node_modules/@angular/*"],
      "@assets/*": ["assets/*"],
      "@environments/*": ["environments/*"],
      "@api/*": ["app/api/*"],
      "@components/*": ["app/components/*"],
      "@login/*": ["app/login/*"],
      "@models/*": ["app/models/*"],
      "@pages/*": ["app/pages/*"],
      "@services/*": ["app/services/*"],
      "@shared/*": ["app/shared/*"]
    }
  },
  "angularCompilerOptions": {
    "fullTemplateTypeCheck": true,
    "strictTemplates": true,
    "strictInjectionParameters": true
  }
}

注意:已尝试使用 "baseUrl": "src"和 "baseUrl": "./src"和 "baseUrl": "./"并且没有任何变化。

这里还有一张我的项目是如何组织的图片

另外发生的一件非常奇怪的事情是，例如我有 2 个服务(我在每个服务中都有问题)一个 城市服务 (正在使用)和色彩服务 (未使用)，城市服务 没有显示任何错误，我可以访问模块定义 (F12)，但在 中色彩服务 具有相同结构的问题出现并以红色显示。

Answer 1

我已经通过以下更改解决了这个问题。

复制来自 tsconfig.base.json 的所有代码或 tsconfig.app.json至tsconfig.json归档并删除 tsconfig.base.json或 tsconfig.app.json .

更改tsconfig.app.json的路径或 tsconfig.base.json延伸至

 {
 "extends": "../tsconfig.json" 
 ...
 }

下面是tsconfig.json的代码文件。

A) 如果你有一个活跃的 ng serve，重启 ng serve

CTRL + C
ng serve

B)如果您没有有效的 ng 服务，请执行以下操作:
