使用Hardhat部署合约遇HH100错误：Goerli网络不存在求助

执行命令 yarn hardhat deploy --network goerli 部署智能合约时，出现错误：

HH100: Network goerli doesn't exist

确认.env文件格式无误，原hardhat.config配置代码如下：

require("@nomicfoundation/hardhat-toolbox")
require("dotenv").config()
require("hardhat-deploy")

/** @type import('hardhat/config').HardhatUserConfig */

const GOERLI_RPC_URL =
      process.env.GOERLI_RPC_URL 
const PRIVATE_KEY = process.env.PRIVATE_KEY
const COINMARKETCAP_API_KEY = process.env.COINMARKETCAP_API_KEY
const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY

module.exports = {
    solidity: {
        compilers: [{ version: "0.8.8" }, { version: "0.6.6" }]
    },
    defaultNetwork: "hardhat",
    namedAccounts: {
        deployer: {
            default: 0 //here this will by default take the first account as deployer
        }
    },
    network: {
        goerli: {
            url: GOERLI_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 5,
            blockConfirmation: 6
        }
    }
}

问题原因 #

核心错误是网络配置字段名拼写错误：Hardhat要求网络配置必须放在networks（复数）字段下，但你写的是network（单数）。Hardhat无法识别这个字段，因此找不到定义的goerli网络。

另外还有一个非当前错误的小问题：blockConfirmation应该改为blockConfirmations（复数），否则后续部署时的区块确认数设置不会生效。

修复后的配置代码 #

require("@nomicfoundation/hardhat-toolbox")
require("dotenv").config()
require("hardhat-deploy")

/** @type import('hardhat/config').HardhatUserConfig */

const GOERLI_RPC_URL =
      process.env.GOERLI_RPC_URL 
const PRIVATE_KEY = process.env.PRIVATE_KEY
const COINMARKETCAP_API_KEY = process.env.COINMARKETCAP_API_KEY
const ETHERSCAN_API_KEY = process.env.ETHERSCAN_API_KEY

module.exports = {
    solidity: {
        compilers: [{ version: "0.8.8" }, { version: "0.6.6" }]
    },
    defaultNetwork: "hardhat",
    namedAccounts: {
        deployer: {
            default: 0 //here this will by default take the first account as deployer
        }
    },
    networks: {
        goerli: {
            url: GOERLI_RPC_URL,
            accounts: [PRIVATE_KEY],
            chainId: 5,
            blockConfirmations: 6
        }
    }
}
