geolocation - Angular 11: Why can't the compiler find 'GeolocationPosition' during compiling? "Cannot find name 'GeolocationPosition'"

Question

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);

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.

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?

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
  }
}

I had the same issue and I solved changing local Angular CLI used by project.
Explanation:
I updated to Angular 11, but I forgot to update Angular CLI. The ng build gave me this output:

Your global Angular CLI version (9.1.7) is greater than your local
version (9.1.0). The local Angular CLI version is used.

Steps:
Update Angular CLI (if necessary)

npm install -g @angular/cli

Update npm

npm install -g npm

Then ng build output become:

Your global Angular CLI version (11.1.2) is greater than your local version (9.1.0). The local Angular CLI version is used.

Install npm-check-updates

npm i -g npm-check-updates

Execute ncu -u to view packages to update.
Execute npm install to update all packages.
After this, all should work.
