npm install --global expo-cli 안될 때

👉🏻 React Native로 구현한 코드를 모바일 폰으로 확인하고 싶은데,android studio 이나 xcode 셋팅 없이 확인할 수 있는 방법으로 Expo가 있다고 한다.

1. expo 설치

npm install --global expo-cli

2. 설치 되지 않고 나온 에러 메세지

npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/expo-cli
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/expo-cli'

3. 구글링을 통한 해결 방법

sudo npm install --global expo-cli

+ 본인의 경우, 맥 유저로 추가 설치

brew update
brew install watchman
