Hardhat部署NFT合约报错：TypeError: AstroMint.deploy is not a function

执行部署命令：

npx hardhat run scripts/deploy.js --network dexitTestnet

出现如下错误：

TypeError: AstroMint.deploy is not a function
    at main (/home/astrodude/dxt/astro-mint/scripts/deploy.js:16:39)

我的deploy.js代码 #

const hardhat = require("hardhat");
const { MerkleTree } = require('merkletreejs');
const keccak256 = require('keccak256');
const whiteList = require('../utils/whitelist');

const BASE_URI = 'ipfs://Qmb5A1fFECM2iFHgUioii2khT814nCi6VU9aHXHHqNxHCK/';
const proxyRegistryAddress = '0xf57b2c51ded3a29e6891aba85459d600256cf317';


async function main() {
    const leadNodes = whiteList.map(address => keccak256(address));
    const merkleTree = new MerkleTree(leadNodes, keccak256, { sortPairs : true });
    const root = merkleTree.getRoot();
    
    const AstroMint = hardhat.ethers.getContractFactory('AstroMint');
    const astroMint = await AstroMint.deploy(BASE_URI, root, proxyRegistryAddress);

    await astroMint.deployed();
    console.log('Astro mint is deployed to ', astroMint.address);

}

// We recommend this pattern to be able to use async/await everywhere
// and properly handle errors.
main().catch((error) => {
  console.error(error);
  process.exitCode = 1;
});

我已经在网上搜索相关解决方案但未找到有效答案，多次重装Hardhat也无法解决该问题。

解决方案 #

问题核心是getContractFactory是异步方法，你没有添加await，导致AstroMint拿到的是Promise对象而非合约工厂实例，因此没有deploy方法。

修改deploy.js中的对应代码：

// 原代码
const AstroMint = hardhat.ethers.getContractFactory('AstroMint');
// 修改为
const AstroMint = await hardhat.ethers.getContractFactory('AstroMint');

同时建议检查以下几点确保部署流程正常：

• 确认合约文件AstroMint.sol存在于contracts/目录下，合约名称与调用时的'AstroMint'完全一致（大小写敏感）
• 执行npx hardhat compile重新编译合约，确保生成了正确的合约artifact
• 确保hardhat.config.js中已正确配置dexitTestnet网络的参数
