HardhatError: HH700:找不到合同的工件

Question

我的代码一直存在这个错误，我提到了另一篇关于'Greeter.sol‘的类似问题的文章，但这似乎不是我的问题。

这是我的.sol文件代码：

//SPDX-License-Identifier: MIT
pragma solidity ^0.8.4;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/access/Ownable.sol";

contract Btc is ERC20, Ownable {
    constructor() ERC20("Dogecoin", "DOGE"){}

    function mint(address to, uint256 amount) public payable{
        _mint(to, amount);
    }

    receive() external payable{}
}

以下是我一直在犯的错误：

HardhatError: HH700:没有找到合同"Dogecoin“的工件。(/home/muskaan/moti-milo/smart-contract/node_modules/hardhat/src/internal/artifacts.ts:478:11) at Artifacts._getArtifactPathFromFiles (/home/muskaan/moti-milo/smart-contract/node_modules/hardhat/src/internal/artifacts.ts:593:19) at Artifacts._getArtifactPath (/home/muskaan/moti-milo/smart-contract/node_modules/hardhat/src/internal/artifacts.ts:275:17) at Artifacts.readArtifact (/home/muskaan )/moti-milo/smart-contract/node_modules/hardhat/src/internal/artifacts.ts:58:26) at getContractFactory (/home/muskaan/moti-milo/smart-contract/node_modules/@nomiclabs/hardhat-ethers/src/internal/helpers.ts:99:22) at main (/home/muskaan/moti-milo/smart-contract/scripts/deploy.js:4:25) at /home/muskaan/moti-milo/smart-contract/scripts/deploy.js:31:9

请帮帮忙，我已经困了一段时间了。

这是我的deploy.js文件：

const { ethers } = require('hardhat')

const main = async() => {
    const dogeFactory = await ethers.getContractFactory('Dogecoin')
    const dogeContract = await dogeFactory.deploy()
    await dogeContract.deployed()
    console.log('Dogecoin deployed to:', dogeContract.address)

    const bitcoinFactory = await ethers.getContractFactory('Btc')
    const bitcoinContract = await bitcoinFactory.deploy()
    await bitcoinContract.deployed()
    console.log('Bitcoin deployed to:', bitcoinContract.address)


    const solanaFactory = await ethers.getContractFactory('Solana')
    const solanaContract = await solanaFactory.deploy()
    await solanaContract.deployed()
    console.log('Solana deployed to:', solanaContract.address)


    const usdcFactory = await ethers.getContractFactory('Usdc')
    const usdcContract = await usdcFactory.deploy()
    await usdcContract.deployed()
    console.log('USDC deployed to:', usdcContract.address)

}


;(async ()=>{
    try{
        await main()
        process.exit(0)
    } catch(error){
        console.error(error)
        process.exit(1)
    }
})()

我使用$ npx hardhat run scripts/deploy.js --network rinkeby部署

由于您将合同命名为“Btc”，因此名称也应该在getContractFactory上同步。

在您的Dogecoin.sol上不要使用：

contract Btc is ERC20, Ownable { ...

相反，请使用：

contract Dogecoin is ERC20, Ownable { ...

然后，不要改变你的deploy.js。然后跑：

npx hardhat clean
npx hardhat deploy scripts/deploy.js --network rinkeby

它应该能正常工作。
