[dklymenk]

Do you want to request a feature or report a bug?

A bug.

Steps to reproduce

npm -g install oclif
oclif generate mynewcli
cd mynewcli
yarn test

What is the current behavior?

The tests pass but eslint shows the following warning:

=============

WARNING: You are currently running a version of TypeScript which is not officially supported by @typescript-eslint/typescript-estree.

You may find that it works just fine, or you may not.

SUPPORTED TYPESCRIPT VERSIONS: >=3.3.1 <4.5.0

YOUR TYPESCRIPT VERSION: 4.5.3

Please only submit bug reports when using the officially supported version.

=============

What is the expected behavior?

There should be no such warning in a freshly bootstrapped project.

---

My node version is v14.18.1 I don't have typescript installed globally on the system. Not sure why the error says your typescript version is 4.5.3 given that the project uses 4.4.3. yarn why @typescript-eslint/typescript-estree reports the following:

yarn why v1.22.17

Done in 0.84s.

Adding the following the .eslintrc works as a workaround, but it doesn't sound a good long term solution.

  "parserOptions": {
    "warnOnUnsupportedTypeScriptVersion": false
  }

Thanks.
