无法将智能契约部署到硬件网络

Question

我为NFT应用程序建立了一个带有硬帽子的项目。我修改hardhat.config.js如下：

const { ALCHEMY_KEY, ACCOUNT_PRIVATE_KEY } = process.env;

module.exports = {
   solidity: "0.8.0",
   defaultNetwork: "hardhat",
   networks: {
    hardhat: {},
    rinkeby: {
      url: `https://eth-rinkeby.alchemyapi.io/v2/${ALCHEMY_KEY}`,
      accounts: [`0x${ACCOUNT_PRIVATE_KEY}`]
    },
    // ethereum: {
    //   chainId: 1,
    //   url: `https://eth-mainnet.alchemyapi.io/v2/${ALCHEMY_KEY}`,
    //   accounts: [`0x${ACCOUNT_PRIVATE_KEY}`]
    // },
  },
}

然后，我在scripts文件夹中创建了一个带有deploy任务的部署脚本

// scripts/deploy.js
const { task } = require("hardhat/config");
const { getAccount } = require("./helpers");

task("deploy", "Deploys the TokenV2.sol contract").setAction(async function (taskArguments, hre) {
    const tokenFactory = await hre.ethers.getContractFactory("TokenV2", getAccount());
    const token = await tokenFactory.deploy();
    await token.deployed()
    console.log(`Contract deployed to address: ${token.address}`);
});

问题在于，当我运行npx hardhat deploy时，它在终端中显示了一个错误：Error: unsupported getDefaultProvider network (operation="getDefaultProvider", network="hardhat", code=NETWORK_ERROR, version=providers/5.5.3)，我错过了什么？我会感谢你的帮助。

我从未在我的作品中使用过defaultNetwork，所以我只使用了以下hardhat.config文件，并且完全没有问题：

{
   "solidity":"0.8.4",
   "networks":{
      "rinkeby":{
         "url":"`https://eth-rinkeby.alchemyapi.io/v2/${ALCHEMY_KEY}`",
         "accounts":[
            "`0x${ACCOUNT_PRIVATE_KEY}`"
         ]
      }
   }
}
