[Mac M1] zsh: command not found: nest

오류 발생

yarn 을 설치하고 yarn 을 통해 nestjs/cli 를 설치하려고 했는데 찾지 못하는 문제 발생

% yarn global add @nestjs/cli
yarn global v1.22.21

% nest new simple-board
zsh: command not found: nest

원인

yarn global 로 패키지를 설치하는 곳과 설치한 패키지를 호출했을 때 읽는 곳이 달라서 생긴 문제

해결방법

경로 재설정이 필요함

1. yarn 의 설치 경로 확인

% yarn global bin
warning package.json: No license field
/Users/[xxxx]/.yarn/bin

2. prefix 확인

% yarn config get prefix
warning package.json: No license field
undefined

내 경우엔 아무것도 설정되어있지 않음

3. prefix 설정

% yarn config set prefix ~/.yarn
yarn config v1.22.21
warning package.json: No license field
success Set "prefix" to "/Users/[xxx]/.yarn".
✨  Done in 0.01s.

4. path 값 변경

% vim ~/.zshrc

설정 파일 진입

export PATH="$PATH:`yarn global bin`"

위의 내용 하단에 저장

% source ~/.zshrc

위의 명령어로 설정 적용

5. 재설치

% yarn global add @nestjs/cli
yarn global v1.22.21
warning package.json: No license field
