[nodejs] ERR_PACKAGE_PATH_NOT_EXPORTED

상황

리액트를 복습하던 중 기존에 공부했던 파일을 열어보려고 했는데 에러가 발생했다.

$ yarn run start

yarn run v1.22.17
$ react-scripts start
node:internal/modules/cjs/loader:488
      throw e;
      ^

해결

• node 버전 문제임을 확인했다. 버전 다운그레이드를 하면 된다고 한다. 현재 node 버전은 18이었다.

• 노드버전 관리 매니저(nvm)을 다운받으면 홈페이지에서 직접 다운로드 할 필요 없이 터미널로 조작 가능하다.

// nvm 다운 방법

curl -o- <https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh> | bash

$ 
> 0.39.0

// 1. 아래 명령어를 입력하면 설치가 선행되어야 한다는 메시지이다.

$ nvm use 16
> N/A: version "16 -> N/A" is not yet installed.
You need to run "nvm install 16" to install it before using it.

// 2. 18 버전 -> 16 버전 다운그레이드 

$ nvm install 16
> Downloading and installing node v16.19.0
Downloading <https://nodejs.org/dist/v16.13.1/node-v16.13.1-darwin-arm64.tar.xz>...

결론: [Error Log] ERR_PACKAGE_PATH_NOT_EXPORTED 에러 메시지는 node버전을 낮춰서 시도해봐라
