실행코드

npx create-react-app ThePurE_Prj

오류 발생 및 원인

터미널에서 npx로 react App을 만들다가 생긴 오류.

You are running `create-react-app` 4.0.3, which is behind the latest release (5.0.1).
We no longer support global installation of Create React App.
Please remove any global installs with one of the following commands:
- npm uninstall -g create-react-app
- yarn global remove create-react-app
The latest instructions for creating a new app can be found here:
https://create-react-app.dev/docs/getting-started/

해석하자면, 버전이 낮아서 안된다는 말. 지우고 다시 설치해야함.

Create React App의 글로벌(전역) 설치를 더 이상 지원하지 않습니다.
다음 명령어를 입력하여 글로벌 설치를 제거하세요
- npm uninstall -g create-react-app
- yarn global remove create-react-app

아 버전 낮다네...

 

해결 방법

전역 설치를 제거한 후 재설치한다.

npm uninstall -g create-react-app
npm i create-react-app
npx create-react-app [프로젝트 이름]

뭔 보안 취약점 이야기하는데 일단 하자.
