我开始了我的第一个区块链教程，它是：

我正在尝试使用安全帽在 Rinkeby 测试网中部署 NFT。以下是我为配置环境所做的步骤：

  • 安装安全帽

  • 在我的 .zshrc 中添加以下环境变量（RINKEBY_RPC_URL、PRIVATE_KEY、MAINNET_RPC_URL）

  • 使用 infuria 创建了一个帐户以获取我的 RINKEBY_RPC_URL：'https://rinkeby.infura.io/v3/My_Project_Id'

  • 从我的 Metamask 添加我的 PRIVATE_KEY

  • 在https://www.alchemy.com/上创建一个帐户以获取我的 MAINNET_RPC_URL：'https://eth-mainnet.alchemyapi.io/v2/My_Project_Id'

  • 我使用https://faucet.rinkeby.io/在我的元掩码（Rinkeby 测试网）上获取以太币。与 LINK 相同

然后当我想使用安全帽部署我的第一个 NFT 时 ->hh deploy --network rinkeby

我有这个错误：

错误信息说：

内在交易成本资金不足

这很奇怪，因为我在 Rinkeby 测试网上添加了一些 Eth 和链接。我错过了什么吗？

编辑(19/07/21)

我取消了 MNEMONIC 部分的注释，并添加了示例中设置的 gas / gasPrice 变量：

rinkeby: {
        url: RINKEBY_RPC_URL,
        accounts: [PRIVATE_KEY],
        //accounts: {
            //mnemonic: MNEMONIC,
        gas: 2100000,
        gasPrice: 8000000000,
        saveDeployments: true,
    },

如您所见，它让我更进一步：

分配给 gas 和 gasPrice 的值有问题吗？

我按照其他答案代码修改的建议评论了助记符，它部分解决了问题。

另外更改 hardhat.config.js 文件的这一部分对我有用：

rinkeby: {
        url: RINKEBY_RPC_URL,
        accounts: [PRIVATE_KEY],
        //accounts: {
            //mnemonic: MNEMONIC,
        gas: 2100000,
        gasPrice: 8000000000,
        saveDeployments: true,
    },

在您的 hardhat.config.js 文件中，确保正确填写“rinkeby”部分以使用您的 PRIVATE_KEY env var，而不是 mnenomic 的。即accounts: [PRIVATE_KEY] 应该取消注释，MNEMONIC 应该注释掉

对我来说，出现错误是因为我的钱包余额不足。

我的钱包总余额为 0.9 ETH。我试图用 1ETH 进行部署：

var contract = await contractFactory.deploy({value: hre.ethers.utils.parseEther("1")});

将值更改为 0.07 解决了它：

var contract = await contractFactory.deploy({value: hre.ethers.utils.parseEther("0.07")});

检查 . 中先前定义的网络之一结束后是否缺少逗号hardhat.config.js。

例如，我试图部署到mainnet，在它上面是这个定义：

ganache: {
    url: 'http://localhost:8545',
    accounts: [PRIVATE_KEY] // <<<< comma was missing here
    // accounts: {
    //     mnemonic: MNEMONIC,
    // }
},
mainnet: {
    url: MAINNET_RPC_URL,

添加逗号，即：[PRIVATE_KEY],为我解决了这个问题。
