[React Native] /bin/bash: ./configure: /bin/sh^M: bad interpreter: No such file or directory 에러 해결하기

MAC OS 환경에서 React Native 개발 환경 구축 중 발생하는 에러 해결하기

 

React Native CLI 를 이용해서 개발을 시작하고 싶은데 중간에 에러가 발생했다.

 

error Error: Failed to install CocoaPods dependencies for iOS project, which is required by this template.
Please try again manually: "cd ./AwesomeProject/ios && pod install".
CocoaPods documentation: https://cocoapods.org/

 

 

그래서 메뉴얼대로 terminal 창에서 cd ./AwesomeProject/ios && pod install 를 쳤더니

또 에러가 발생했다.

 

 

에러의 원인은 다음과 같다.

 

키보드에서 enter 버튼을 누를 때마다 line ending에 보이지 않는 문자를 삽입하는데 각 운영 체제에 따라 line ending이 다르게 처리된다. Flipper-Glog를 설치할 때 Git에서 받아오는데 Windows 컴퓨터에서 작업 된 프로젝트를 Mac OS에서 사용 할 경우 Git에서 예기치 않은 결과가 발생할 수 있다. 그래서 line ending을 자동으로 처리하도록 Git을 구성해야한다.

 

 

Global settings for line endings

 

기존에 만들었던 프로젝트를 삭제 한 뒤에 terminal 창에서 다음 명령을 실행한다.

 

git config --global core.autocrlf input

 

그러고 다시 프로젝트를 생성하면 아주 잘 된다. 문제해결 완료!
