[Error - 10:31:59 AM] The eslint library loaded from /Users/ruden/Desktop/development/2022/test/node_modules/eslint/lib/api.js doesn't export a CLIEngine. You need at least eslint@1.0.0

package.json eslint 설치 버전은 8버전이 설치되어 있는 것을 확인할 수 있습니다.

{
  "devDependencies": {
	...
    "eslint": "^8.9.0"
  },
}

vscode-eslint에서 eslint@8을 지원하지 않기 때문에 발생한 에러입니다. 아마 추후에 업데이트를 통해 지원될 예정할 것이라 예상하지만, 현재는 직접 설치해서 해결해야되는 불편함이 있기 때문에 업데이트 되기 전까지는 7버전을 사용하는 것을 추천합니다.
