개발환경 및 상황

window, Node 22.14.0, react: ^19.0.0, react-native: 0.79.2, expo ^53.0.9

SDK 53으로 올리면서 react19이 강제 되어, react19를 사용하였습니다. 대부분의 라이브러리들이 react18을 기반으로 되어있어 의존성 충돌이 일어나, 강의에서 사용된 라이브러리는 --legacy-peer-deps로 설치하여 개발은 가능하였습니다.

문제

라이브러리 사용까지는 상관없었는데, '[7-5] 개발빌드 실행 및 알림 수신하기'의 EAS 빌드를 위하여 eas build --profile development (--clear-cache) 를 사용하였는데 npm ci단계에서 peer dependecy충돌로 빌드가 실패하고있습니다.

시도 했던 방법

• npm ci 우회

npm ci 를 우회하기 위하여 pacakge.json에 npm install --legacy-peer-deps 로 우회하는 쉘스크립트도 사용해봤는데, (chmod 로 권한 설정 & LF 줄바꿈) permission denied 로 빌드되지 않았습니다. "scripts": {

"start": "expo start",

"eas-build-pre-install": ".eas/build/pre-install.sh", .eos/build/pre-install.sh ,

...}

• 라이브러리 업데이트

타입만 우선적으로 업데이트하였는데( types/@react18.3.12 => 19.1.8, )

그 외에도 react19가 지원하지 않는 다른 라이브러리들 (react-test-render 등)이 있어서 실패.

❗질문 작성시 꼭 참고해주세요

• 에러 메세지에서 단서를 찾을 수 있는 경우가 많습니다. 에러 메세지를 읽고 한번 검색해보시는것을 추천드립니다.

• 질문글을 작성하실때는, 현재 문제(또는 에러)와 코드나 github을 첨부해주세요.

• 개발중인 OS, ReactNative, Node 버전 등의 개발환경을 알려주셔야합니다.

• 에러메세지는 일부분이 아닌 전체 상황을 올려주세요. 일부만 보여주시면 답변이 어렵습니다.

• 에러 잘라서 올리시면 안됩니다!

(에러 일부만 자르거나 일부만 복사하지말아주세요)
