部署脚本代码（Node v18.17.1） #

const ethers = require("ethers");
const fs = require("fs");

// we can only use await keyword inside async functions

async function main() {
  const rpcURL = "http://127.0.0.1:7545";
  const provider = new ethers.JsonRpcProvider(rpcURL);

  const wallet = new ethers.Wallet(
    "0xdae2a8f600d25556f9863f2a5f5134241fc860f5469e71e6205f5b1dc517c576",
    provider
  );

  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf-8");

  const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf-8"
  );

  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying, please wait...");
  const contract = await contractFactory.deploy(); // STOP here, wait for the contract to deploy
  const transactionReceipt = await contract.deployTransaction.wait(1);
  console.log(
    `Here is the deployment transaction: ${contract.deployTransaction}`
  );
  console.log(`Here is the transaction receipt: ${transactionReceipt}`);
}

main()
  .then(() => process.exit(0))
  .catch((err) => {
    console.error(err);
    process.exit(1);
  });

Solidity合约代码（0.8.7-fixed） #

// SPDX-License-Identifier: MIT

pragma solidity 0.8.7;

contract SimpleStorage {
    uint256 favoriteNumber;

    struct People {
        uint256 favoriteNumber;
        string name;
    }
    // uint256[] public anArray;
    People[] public people;

    mapping(string => uint256) public nameToFavoriteNumber;

    function store(uint256 _favoriteNumber) public {
        favoriteNumber = _favoriteNumber;
    }

    function retrieve() public view returns (uint256) {
        return favoriteNumber;
    }

    function addPerson(string memory _name, uint256 _favoriteNumber) public {
        people.push(People(_favoriteNumber, _name));
        nameToFavoriteNumber[_name] = _favoriteNumber;
    }
}

环境配置 #

• ethers.js - 6.2.3
• solc - 0.8.7
• ganache
• node - v18.17.1

解决方案 #

问题根源是ethers.js v6的API变更：v6版本移除了contract.deployTransaction属性，改用contract.deploymentTransaction()方法获取部署交易对象。

修改部署脚本中的对应代码：

// 原代码
const transactionReceipt = await contract.deployTransaction.wait(1);
console.log(`Here is the deployment transaction: ${contract.deployTransaction}`);

// 修改后代码
const deploymentTx = contract.deploymentTransaction();
const transactionReceipt = await deploymentTx.wait(1);
console.log(`Here is the deployment transaction: ${JSON.stringify(deploymentTx, null, 2)}`);

修改后重新运行脚本即可完成正常部署。
