如何复位/清洁重启硬帽

Question

我开始使用Hardhat在我的本地系统上部署重力合约，它第一次成功部署，之后我运行一个脚本来创建Gravatars，但当我运行yarn Hardhat node—hostname 0.0.0.0时失败． 它显示了以下错误

*错误:事务恢复没有一个原因字符串在。(0 x5fbdb2315678afecb367f032d93f642f64180aa3)在HardhatNode。_mineBlockWithPendingTxs (/home/ahsan nftiple/市场/node_modules/建筑工人/src/内部/hardhat-network/供应商/node.ts: 1582:23)在HardhatNode。mineBlock (/home/ahsan nftiple/市场/node_modules/建筑工人/src/内部/hardhat-network/供应商/node.ts: 435:16)在EthModule。_sendTransactionAndReturnHash (/home/ahsan/nftiple/市场/node_modules/建筑工人/src/内部/hardhat-network/供应商/模块/eth.ts: 1494:18)在HardhatNetworkProvider。_sendWithLogging (/home/ahsan nftiple/市场/node_modules/建筑工人/src/内部/hardhat-network/供应商/provider.ts: 129:22)在HardhatNetworkProvider。请求(/home/ahsan nftiple/市场/node_modules/建筑工人/src/内部/hardhat-network/供应商/provider.ts: 106:18)*

这是我的部署脚本和重力的代码。Sol合同文件

import {HardhatRuntimeEnvironment} from "hardhat/types";
import {DeployFunction} from "hardhat-deploy/types";
const func: DeployFunction = async (hre: HardhatRuntimeEnvironment) => {
const {deployments, getNamedAccounts} = hre;
const {deployer} = await getNamedAccounts();
const deployResult = await deployments.deploy("GravatarRegistry", {
from: deployer,
log: true,
});
const Registry = await hre.ethers.getContractFactory('GravatarRegistry');
const registry = await Registry.attach(deployResult.address);
registry.createGravatar('Virat','https://img1.hscicdn.com/image/upload/f_auto,t_gn_f_345/lsci/db/PICTURES/CMS/316600/316605.png');

}
// the gravatar at position 0 of gravatars[]
// is fake
// it's a mythical gravatar
// that doesn't really exist
// dani will invoke this function once when this contract is deployed
// but then no more
function setMythicalGravatar() public {
require(msg.sender == 0x8d3e809Fbd258083a5Ba004a527159Da535c8abA);
gravatars.push(Gravatar(address(0), " ", " "));
}
}

我正在使用hardhat-deploy，并且我知道hardhat-deploy试图避免重新部署相同的契约。是否有任何方法可以将我的硬帽重置为空白/干净状态，以便我摆脱此错误。我已经尝试删除node_modules目录多次，但无济于事

Answer 1

如果这是一个硬帽部署错误，并且与重新部署有关，您可以尝试在控制台中运行以下命令:

yarn hardhat deploy --reset

查看https://github.com/wighawag/hardhat-deploy#deploy-scripts获取更多信息。

但是，关于你的错误日志，有一个没有原因字符串的tx返回，所以你可以检查是否有一些require语句正在触发或检查如果你触发:

会发生什么

registry.createGravatar('Sachin','https://img1.hscicdn.com/image/upload/f_auto,t_gn_f_345/lsci/db/PICTURES/CMS/316400/316486.png');// FAILS HERE

所以，我建议检查你是否做了两次事情，一个require语句触发了回归，或者你检查你的合同-你可以使用硬帽控制台https://hardhat.org/guides/hardhat-console在控制台记录，而你执行函数(只是把console.log()在某些点，你想确保它们被执行或导致问题)。
