요즘 리엑트 네이티브 공부중인데, 어느날 갑자기 빌드가 안되어서 검색해봤다. 

어떤 블로거는 캐쉬삭제만 해도 다시 빌드가 잘 되었다고는 하던데,, 나는 안되더라.

위에 링크해둔 방법대로 해서 해결되었다. 

위 방법을 요약하자면, 

1. 프로젝트 폴더 내 android 폴더로 이동 후 

2. 아래 명령어를 실행해서 캐쉬를 삭제한다.

./gradlew cleanBuildCache

 

3. android/app/ 경로의 build.gradle 파일을 찾아서 에디터로 열고, 

아래 내용을 붙여넣기 한다. (packagingOptions 추가)

android {

packagingOptions {
    pickFirst 'lib/x86/libc++_shared.so'
    pickFirst 'lib/x86_64/libc++_shared.so'
    pickFirst 'lib/armeabi-v7a/libc++_shared.so'
    pickFirst 'lib/arm64-v8a/libc++_shared.so'
}

/** rest of your code here **/

 

그리고는 빌드 !

npx react-native run-android
