使用Hardhat部署智能合约时出错 - 错误HH9：加载Hardhat的配置时出错

Question

试图使用Hardhat部署智能合约，但遇到配置错误。

以下是完整的错误详细信息

Error HH9: Error while loading Hardhat's configuration.
You probably tried to import the "hardhat" module from your config or a file imported from it.
This is not possible, as Hardhat can't be initialized while its config is being defined.

所有的插件似乎都已正确安装。

deploy.js

const hre = require("hardhat");
async function main() {
const TestContract = await hre.ethers.getContractFactory("TestContract");
const superInstance = await TestContract.deploy("TestContractHAT", "SMC");
await superInstance.deployed();
console.log("contract was deployed to:", superInstance.address());
}
// We recommend this pattern to be able to use async/await everywhere
// and properly handle errors.
main()
.then(() => process.exit(0))
.catch((error) => {
console.error(error);
process.exit(1);
});

package.json

"version": "1.0.0",

Hardhat.config

const { ethers } = require("hardhat");
require('@nomiclabs/hardhat-waffle');
require("@nomiclabs/hardhat-ethers");
require('@openzeppelin/hardhat-upgrades');

require("dotenv").config();
// This is a sample Hardhat task. To learn how to create your own go to
// https://hardhat.org/guides/create-task.html
task("accounts", "Prints the list of accounts", async (taskArgs, hre) => {
const accounts = await hre.ethers.getSigners();  
for (const account of accounts) {
console.log(account.address);
}
});
// You need to export an object to set up your config
// Go to https://hardhat.org/config/ to learn more
/**
* @type import('hardhat/config').HardhatUserConfig
*/
module.exports = {
solidity: "0.8.2",
networks: {
mumbai: {
url: process.env.MUMBAI_URL,
account: process.env.PRIVATE_KEY
}
}
};

任何指针都是有用的。感谢

Answer 1

如错误所示，您正在安全帽配置中导入hardhat模块。

You probably tried to import the "hardhat" module from your config or a file imported from it. This is not possible, as Hardhat can't be initialized while its config is being defined.

删除线路

const { ethers } = require("hardhat");

并且错误应该消失

Answer 2

只需移除const{ethers}＝require("hardhat"(；

或const｛hardhatArguments｝=require("hardhat"(；

或任何其他需要安全帽的
