Error: "prettier/@typescript-eslint" has been merged into "prettier" in eslint-config-prettier 8.0.0

Overview

We are having an issue using prettier-standard alongside eslint & eslint-config-prettier. Upon running prettier-standard --lint we receive an error which seems to be related to this change in eslint-config-prettier. This error does not present when eslint-config-prettier is removed from our package.json.

Steps to re-create

• In a clean folder run npm init
• Run npm install --save-dev prettier-standard eslint eslint-config-prettier
• Add this script to package.json: "lint": "prettier-standard --lint *"
• run npm run lint

Expected results

➜ npm run lint

> [email protected] lint /Users/clive/Developer/learning/recreate-prettier-error
> prettier-standard --lint *

package-lock.json 164ms
package.json 5ms
All matched files use Standard code style!

Actual results

➜ npm run lint

> [email protected] lint /Users/clive/Developer/learning/recreate-prettier-error
> prettier-standard --lint *

I'm having the same problem but this project seems unmaintained, no updates for more than a year unfortunately.

Read this: https://github.com/prettier/eslint-config-prettier/blob/main/CHANGELOG.md#version-800-2021-02-21

in my case, in .eslintrc file I had:

  "extends": [
    "standard",
    "standard-react",
    "plugin:prettier/recommended",
    "prettier/standard",
    "prettier/react"
  ],

and now I have:

  "extends": [
    "standard-react",
    "plugin:prettier/recommended"
  ],
