部署Solidity合约遇HH702错误：无效工件路径问题求助

每次执行合约部署脚本都会触发HH702错误，提示无效的artifact路径，正确的大小写敏感路径为E:\Block Chain Projects\SET OOD\artifacts\contracts\Mood.sol\Mood.json，原路径中错误地将Mood.sol写为MOOD.sol。

错误信息 #

Error HH702: Invalid artifact path E:\Block Chain Projects\SET OOD\artifacts\contracts\MOOD.sol\Mood.json, its correct case-sensitive path is E:\Block Chain Projects\SET OOD\artifacts\contracts\Mood.sol\Mood.json

deploy.js 文件代码 #

async function main()
{
  const {deployers} =await  ethers.getSigners();
  const MOODCONTRACT = await ethers.getContractFactory('Mood');
  const moodcontract =await  MOODCONTRACT.deploy();
  console.log("the contract is deployed"+moodcontract.address);
}
main().then(
  ()=>process.exit(0)
).catch(err => {
  console.log(err);
  process.exit(1);
})

Mood.sol 合约代码 #

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.9;

contract Mood {
    string mood;
    function Setmood(string memory _mood) public {
        mood = _mood;
    }
    function Getmood() public view returns(string memory)
    {
        return mood;
    }
}

解决方案 #

• 确认合约文件名是Mood.sol，而非大写的MOOD.sol，保持文件名大小写与artifact路径一致
• 删除项目根目录下的artifacts和cache文件夹，清除旧编译缓存
• 重新执行npx hardhat compile编译合约，再运行部署脚本即可解决问题
