error: unknown option `--print-config' in a new nestjs project

[itays]

🐛 Bug Report

• tslint-to-eslint-config version: 0.1.9
• ESLint version: 6.0.1
• Node version: 12.4.0

Actual Behavior

currently nestjs framework still ships with tslint. I created a new nestjs project and run npx tslint-to-eslint-config and got:

Could not start tslint-to-eslint:
Command failed: tslint --print-config "./tslint.json"
error: unknown option `--print-config'

Expected Behavior

eslint json file should be created

Reproduction

install the nestjs cli tool:
npm i -g @nestjs/cli
create a nestjs project:
nest new project-name
cd into the newly created project and run npx tslint-to-eslint-config

👋 Thanks for the bug report @itays! If you update your TSLint version to 5.18.0, the issue will go away.

The problem is that TSLint added the --print-config flag only recently, and tslint-to-eslint-config relies on it. I'll send a PR to add an explicit dependency to this package on sufficient tslint and typescript versions.

[JoshuaKGoldberg]

This should be fixed in 0.2.0:

npx tslint-to-eslint-config@0.2

Please do post here if that doesn't fix this bug for you! 🚀

[JoshuaKGoldberg]

FYI: as of 0.2.2, the error message when the TSLint version is too low will explicitly indicate it should be updated.

❌ Could not start tslint-to-eslint: ❌
TSLint v5.18 required. Please update your version.

@JoshuaKGoldberg Do I need exactly 5.18v?

[JoshuaKGoldberg]

Oh interesting. You should be able to use 5.20.1, and generally anything >=5.18. Would you mind filing a new issue with your project details?

Oddly still getting this in a NextJS project where we use TSLint:

Ah, it was:
"extends": ["tslint-react", "tslint-config-prettier", "react-hooks"],

react-hooks never resolved, I don't even remember if that ever resolved to anything or when that was added. Removed and works.
