[1/18] 1 .새 프로젝트 생성

환경설정이 끝났으니 workspace를 만들어보자

 

react native가 필요한 패키지를 다 설치해주기 때문에 명령어 한줄로 끝

npx react-native init SelfPraise

그럼 SelfPraise라는 폴더가 생기면서 생성 완료~

아래 폴더와 파일들이 생긴다. 굵은 글씨가 폴더.

.
├── App.js
├── __tests__
├── android
├── app.json
├── babel.config.js
├── index.js
├── ios
├── metro.config.js
├── node_modules
├── package.json
└── yarn.lock

 

안드로이드로 실행하려면 아래 명령어 복붙하면 된다

npx react-native run-android

30초 정도 기다리니 에뮬레이터가 실행되고 마이크 접근 권한을 물어본다. 허용 안할걸ㅠ

 

(대충 빌드 실패했다는 뜻 )

BUILD FAILED in 2m 31s

찾아보니 license 창이 떴을 때 yes 안해서 그런가봄...

https://stackoverflow.com/questions/39760172/you-have-not-accepted-the-license-agreements-of-the-following-sdk-components

 

아래 명령어로 모두 yes 해준다

$ yes | ANDROID_HOME/tools/bin/sdkmanager --licenses

 

다시 안드로이드 빌드 하면 실행된다~

 

안녕 리액트
