Node v17.8.0

위와 같은 에러가 발생했을 땐 간단하게 node version 을 변경하여 해결해주면 된다.

~/web3js/Stest ❯ nvm ls
       v16.14.2
->      v17.8.0
        v18.8.0
         system

~/web3js/Stest ❯ nvm use v16.14.2
Now using node v16.14.2 (npm v8.5.0)

truffle init 을 하면 다음과 같이 생성되야하는데

이중 truffle.js 가 생성되지 않았다.

이전 truffle 버전에서는 운영체제에 따라 truffle.js, truffle-config.js 로 구분되어 있었는데

최근 트러플 버전에서는 truffle-config.js 하나로 통일되었다.

결국, 그냥 버전이 다른 문제!
