This is probably an incompatibility issue between your TypeScript version and some of your @types packages. I'll walk you through the solution with a step by step example:

  1. Go to your package.json and look for you TypeScript and @types versions:
  "devDependencies": {
    // ...
    "@types/deep-freeze": "0.1.1",
    "@types/jasmine": "3.5.10",
    "@types/lodash.isequal": "4.5.5",
    "@types/lodash.mergewith": "4.6.6",
    "@types/lodash.remove": "4.7.6",
    "@types/lodash.some": "4.6.6",
    // ...
    "typescript": "2.9.2",
    // ...
  }

  1. For each of your @types packages do: npm dist-tags @types/<your-types-package-name>. You'll now see a table that indicates which TypeScript version works with each of the @types package version

  2. Update your @types in your package.json with the corresponding versions

If the solution does not work try updating TypeScript to a newer version!

In case your using "typescript": "~3.1.6" in the package.json file, change "@types/node" version to "@types/node": "14.6.2", in the package.json file, That solved my problem..

  • Very nice! This was my problem too, It happens when typescript is not compatible with your node version. – flup May 04 '22 at 17:46
