The Angular Compiler requires TypeScript 3 4 0 and 3 5 0 but 3 5 3 was found instead

Question

I'm getting the following error when I do npm run build:

The Angular Compiler requires TypeScript >=3.4.0 and <3.5.0 but 3.5.3 was found instead.

I've tried following things separately:

npm install typescript@">=3.4.0 <3.5.0". Then deleted node_modules and package.json. Run npm install

npm update --force. Then deleted node_modules and package.json. Run npm install

I'm still getting the error:

My package.json contains following dependencies:

  "dependencies": {
    "@angular/animations": "8.1.0",
    "@angular/cdk": "^8.0.2",
    "@angular/cli": "^8.1.0",

    "ts-node": "~8.3.0",
    "tslint": "~5.18.0",
    "typescript": "^3.4.5"
  }

ng --version gives following output:
