我有一个固体文件@ 0.5.0，带有工厂合同和子合同。我可以编译（尽管您会在ethereum / compile.js中所有注释掉的行中注意到试验和错误）。

运行... options.CallbackPath = "signin-oidc/b"; ...会导致错误。

node ethereum/deploy.js

我已经确认此合同代码可以混音使用。我尝试在Attempting to deploy from account 0xff831110eeA8322639bee543AD1477AD9f472E22 UnhandledPromiseRejectionWarning: Error: The contract code couldn't be stored, please check your gas limit. ... ... ...

我在solidity 0.4.17的另一个项目上使用了此精确设置，并且部署工作正常（尽管编译有所不同）。这是上一个项目的仓库：https://github.com/aljmiller87/ethereum-kickstart

ethereum / deploy.js

0.0.5

package.json：

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

您可以使用克隆工厂合同代替新关键字，因为它在汽油方面非常便宜，这是参考链接：clone-factory以及为什么更好"Attack Of The Clones — How DDA Contracts Are So Cheap To Deploy"

Answer 2

发现问题出在坚固性代码中。我试图保留合同类型的数组，而不是保留创建的合同的地址。

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 {
...
