Angular 11:为什么编译器在编译期间找不到'GeolocationPosition'?“找不到名称'GeolocationPosition'"； [英] Angular 11: Why can't the compiler find 'GeolocationPosition' during compiling? "Cannot find name 'GeolocationPosition'"

问题描述

为什么角度编译器找不到 GeolocationPosition 和 GeolocationPositionError ?VSC不会给出错误，只有在编译时才会给出错误.

Why does the angular compiler can't find GeolocationPosition and GeolocationPositionError? VSC doesn't give an error and only during compiling it gives me an error.

Error: src/app/modules/shared/services/position.service.ts:10:46 - error TS2304: Cannot find name 'GeolocationPosition'.

10   private positionSource = new ReplaySubject<GeolocationPosition>(1);

我通过改用 any 类型来解决此问题，但是我很好奇为什么Angular会给我错误以及如何解决此问题.

I worked around this by putting the any type instead, but I'm just curious why Angular is giving me the error and how I can fix this.

我已经尝试了不同的编译器目标( es5 ， es6 ， es2018 )，但是没有运气.已经安装了 @ types/core-js ，但是也没有任何运气.我可能缺少任何@types模块吗?

I've already tried different compiler targets (es5, es6, es2018) but with no luck. Already installed @types/core-js but also without any luck. Is there any @types module that I'm missing perhaps?

这是我当前的tsconfig.json

This is my current tsconfig.json

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "forceConsistentCasingInFileNames": true,
    "strict": true,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true,
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "moduleResolution": "node",
    "importHelpers": true,
    "target": "es5",
    "module": "es2020",
    "lib": [
      "es2018",
      "dom"
    ]
  },
  "angularCompilerOptions": {
    "strictInjectionParameters": true,
    "strictInputAccessModifiers": true,
    "strictTemplates": true
  }
}

推荐答案

在打字稿4.0.x中，此类型称为 Position .在打字稿4.1.x中，它已重命名为 GeolocationPosition .

In typescript 4.0.x this type was called Position. In typescript 4.1.x it was renamed to GeolocationPosition.

我想您会发现您的VS Code使用的是内置的打字稿版本，而您的项目使用的是较早版本.

I think you'll find that your VS Code is using its built in version of typescript and that your project is using an earlier version.

要解决:

npm install --save-dev typescript@4.1.2
