npm run dev 명령어 오류

Question

안녕하세요. 좋은 강의 감사합니다! 다름이 아니라 1분 53초 즈음에 npm run dev 명령어 실행이 되지않아서요. 명령어를 입력하면 아래와 같은 에러메세지가 나옵니다. > react-boiler-plate@1.0.0 dev > concurrently "npm run backend" "npm run start --prefix client" sh: concurrently: command not found npm ERR! code 127 npm ERR! path /Users/naeaipon/Documents/react:node.js clone coding project-1/boilerplate-mern-stack-master npm ERR! command failed npm ERR! command sh -c concurrently "npm run backend" "npm run start --prefix client" npm ERR! A complete log of this run can be found in: npm ERR! /Users/naeaipon/.npm/_logs/2021-01-11T05_17_12_835Z-debug.log
