TypeError:无法读取未定义的AND属性错误:处理跳过函数时出错

Question

我收到的错误(在部署时，请参阅代码末尾)

Error: ERROR processing skip func of /home/amey/hardhat/hardhat-fund-me/deploy/01-deploy-fund-me.js:

TypeError: Cannot read properties of undefined (reading 'ethUsdPriceFeed')

当我点击错误时，我会看到01-deploy-fund-me.js(在另一个文件中)中的这一行

ethUsdPriceFeedAddress = networkConfig[chainId]["ethUsdPriceFeed"]

这是我试图部署的代码

const { network, getNamedAccounts, deployments } = require("hardhat")
const {
developmentChains,
DECIMALS,
INITIAL_ANSWER,
} = require("../helper-hardhat-config")
module.exports = async ({ getNamedAccounts, deployment }) => {
const { deploy, log } = deployments
const { deployer } = await getNamedAccounts()
const chainId = network.config.chainId
if (developmentChains.includes(network.name)) {
log("Local network detected! Deploying mocks...")
await deploy("MockV3Aggregator", {
contract: "MockV3Aggregator",
from: deployer,
log: true,
args: (DECIMALS, INITIAL_ANSWER),
})
log("Mocks Deployed!")
log("--------------------------------------------------------------")
}
}
module.exports.tags = ["all", "mocks"]

谢谢。

我也遇到了同样的问题。我的问题的解决方案是添加：

namedAccounts: {
deployer: {
default: 0, // here this will by default take the first account as deployer
1: 0 // similarly on mainnet it will take the first account as deployer. Note though that depending on how hardhat network are configured, the account 0 on one network can be different than on another
}
}

我也遇到了同样的问题。如果您使用console.log()注销部署程序变量，它将返回空值。这意味着getNamedAccounts无法解析帐户。但是，如果使用mock，部署程序变量会返回一个帐号。如果您在hardhat.config.js文件中使用元任务帐户no硬编码部署程序变量。它将返回一个未知的签名者错误。我仍然被困在这个问题上。

您之所以出现此错误，是因为您缺少一个重要的安全帽依赖项"安全帽华夫饼"；尝试

npm install --save-dev @nomiclabs/hardhat-waffle

在hardhat.config.js中添加

require("@nomiclabs/hardhat-waffle");

这应该有效！

在您的网络中配置属性"ethUsdPriceFeed"；定义。试着像下面的一样定义它

export const networkConfig :networkConfigType= {
4: {
name: "rinkeby",
ethUsdPriceFeed: "0x8A753747A1Fa494EC906cE90E9f37563A8AF630e",
},
137: {
name: "polygon",
ethUsdPriceFeed: "0xF9680D99D6C9589e2a93a78A04A279e509205945",
},
};
