部署到rinkeby时出错

Question

我试图在rinkeby上部署我的智能合同，但得到了以下错误。任何洞察力都是非常感谢的。

(node:3817) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: The contract code couldn't be stored, please check your gas limit.
(node:3817) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

部署脚本

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

const provider = new HDWalletProvider(
  '(metamask 12 word seed phrase)',
  'https://rinkeby.infura.io/4PHzobtaMWvurQjWma6j'
);
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(
    JSON.parse(compiledFactory.interface)
  )
    .deploy({ data: compiledFactory.bytecode })
    .send({ gas: '1000000', from: accounts[0] });

  console.log('Contract deployed to', result.options.address);
};
deploy();

你提供了1,000,000股汽油，但正如错误说的，“检查你的汽油限额。”

看起来你需要更接近200万的汽油。
