使用nodejs部署solid代码得到错误下面我分享代码

Question

首先呈现坚实的编译代码Compile.js

const path = require('path');
const solc = require('solc');
const fs = require('fs-extra');
const buildPath = path.resolve(__dirname, 'build');
fs.removeSync(buildPath);
const campaignPath = path.resolve(__dirname, 'contracts', 'Campaign.sol');
const source = fs.readFileSync(campaignPath, 'UTF-8');
var input = {
    language: 'Solidity',
    sources: {
        'Campaign.sol' : {
            content: source
        }
    },
    settings: {
        outputSelection: {
            '*': {
                '*': [ '*' ]
            }
        }
    }
};
var output = JSON.parse(solc.compile(JSON.stringify(input)));
fs.ensureDirSync(buildPath);
for(contractName in output.contracts['Campaign.sol']){
    fs.outputJSONSync(
        path.resolve(buildPath, contractName + '.json'),
        output.contracts['Campaign.sol'][contractName]
    );
}

我的哪个编译代码是对的还是错的?

这是我的deploy.js

const HDWalletProvider = require('truffle-hdwallet-provider');
const Web3 = require('web3');
const compiledFactory = require('./build/CampaignFactory.json');
const provider = new HDWalletProvider(
    // process.env.NEXT_PUBLIC_META_MASK,
    // process.env.NEXT_PUBLIC_INFURA_API
    'dove poppih solid recycle impose piano leisure twin pyramid afraid spolik nose',
    'https://sepolia.infura.io/v3/fcuijy7e97ee2f475da508dc6d1dc42701'
);
const web3 = new Web3(provider);
const deploy = async () => {
    const accounts = await web3.eth.getAccounts();
    console.log('attempting to deploy from account: ', accounts[0]);
    const result = await new web3.eth.Contract(compiledFactory.abi)
    .deploy({data: compiledFactory.evm.bytecode.object})
    .send( {from:accounts[0], gas:'125653'});
    console.log('Contract deployed to: ', result.options.address);
    provider.engine.stop();
};
deploy();

上面的代码得到错误

attempting to deploy from account:  0x909CD220D8707e052C0a6E94FA167227fFfc7865
node:internal/process/promises:279
            triggerUncaughtException(err, true /* fromPromise */);

Error: insufficient funds for gas * price + value

Answer 1

这可能是一个bug，请记住，如果您的帐户中没有足够的ETH，如果您的node与网络不同步，或者如果您没有指定天然气价格，则此错误很常见或者是其他命令有一点错误。

gas * price + value实际上意味着MAXGas * price

您可以尝试此解决方案将所有值转换为hex(如果使用bash则使用bc)，并确保同时指定(gas和gasPrice)，并将所有值包含在单引号中:

eth.sendTransaction({from:'0x123456', to:'0x123456', value: '0x8AC4270ACC4B7FF7', gas: '0x5208', gasPrice: '0x4A817C800'});"

其他解决方案可以是'降级版本，因为有时它会意外地导致这个问题。
