我有一个 solidity 文件 @0.5.0，其中包含一份工厂合同和一份子合同。我可以正常编译（尽管您会注意到 ethereum/compile.js 中所有注释掉的行中的反复试验）。

运行 node ethereum/deploy.js 结果出错。:

Attempting to deploy from account 0xff831110eeA8322639bee543AD1477AD9f472E22 
UnhandledPromiseRejectionWarning: Error: The contract code couldn't be stored, please check your gas limit.
...

...
UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)

我已经确认此合同代码在混音中有效。我尝试在 0.0.3 和 0.0.5 上使用 truffle-hdwallet-provider （并相应地更新 .deploy() 和 .send() 参数。

我在另一个项目 @solidity 0.4.17 上使用了这个精确设置并且部署工作正常（尽管编译是不同的）。这是以前项目的回购：https://github.com/aljmiller87/ethereum-kickstart

ethereum/deploy.js

const HDWalletProvider = require('truffle-hdwallet-provider');
const Web3 = require('web3');
const compiledContract = require('./build/ThreeJudge.json');

const compiledFactory = compiledContract.ContractFactory
const compiledFactoryABI = compiledFactory.abi;
const compiledFactoryBytecode = compiledFactory.evm.bytecode.object;


const provider = new HDWalletProvider(
    `${process.env.SEED_KEY}`,
    'https://rinkeby.infura.io/v3/ad66eb1337e043b2b50abe1323fff5f0'
);

const web3 = new Web3(provider);

const deploy = async () => {
    // Get account to deploy from
    const accounts = await web3.eth.getAccounts();
    console.log('Attempting to deploy from account', accounts[0]);

    // deploy code
    const result = await new web3.eth.Contract(compiledFactoryABI)
    .deploy({ data: '0x' + compiledFactoryBytecode })
    .send({ gas: '1000000', from: accounts[0] });


    console.log('result address', result.options.address)
};

deploy();

Answer 1

发现问题出在solidity代码中。我试图保留合同类型的数组，而不是创建合同的地址。

原文：

contract ContractFactory {
    ThreeJudge[] public deployedContracts;

    function createContract(address payable _buyer, address payable _seller) public {
        ThreeJudge newContract = new ThreeJudge(_buyer, _seller);
        deployedContracts.push(newContract);
    }

    function getDeployedContracts() public view returns (ThreeJudge[] memory) {
        return deployedContracts;
    }
}

contract ThreeJudge {
...

修复：

contract ContractFactory {
    address[] public deployedContracts;

    function createContract(address payable _buyer, address payable _seller) public {
        ThreeJudge newContract = new ThreeJudge(_buyer, _seller);
        deployedContracts.push(address(newContract));
    }

    function getCampaignsByAddress() public view returns (address[] memory) {
        return deployedContracts;
    }
}

contract ThreeJudge {
...

您可以使用克隆工厂合约而不是新关键字，因为它在 gas 方面非常便宜，这里是 link 供参考：clone-factory and why it is better "Attack Of The Clones — How DDA Contracts Are So Cheap To Deploy"
