Hardhat v2 설치..(변경)
- 수업에서 hardhat v2를 이용한다며 해당 코드를 줌.
(v3와 큰 차이는없으나 처음 hardhat을 사용하는 학생 입장에서는 여러 오류가 발생할 수 있으니 꼭 버전을 동일시해서 수업을 진행하시는 것을 권장드립니다.)라고 함
nvm use v20.19.4
npm install hardhat@2.22.19
npx hardhat init이거 차례대로 입력하니까
// package.json 파일에 해당 코드가 추가됨
"@nomicfoundation/hardhat-toolbox-viem": "^3.0.0", //
"hardhat": ~~
"ts-node": "^10.9.2"이렇게 나옴..
- typescript 설치라는데 안해도 될 듯
(결과물이 동일하게 나온듯함)
