错误：部署到 rinkeby 时交易价格过低

Question

下面的代码在控制台中的“尝试从帐户部署：..”行停止工作，一段时间后它给出“Trnsaction 未在 750 秒内开采，请确保您的交易已正确发送”，早些时候它是给出错误“交易低估”，我尝试添加gasPrice并提高gas价格，但仍然得到相同的结果。谁能帮帮我？

const hdWalletProvider = require('@truffle/hdwallet-provider')
const Web3 = require('web3')
const { interface, bytecode } = require('./compile')

const provider = new hdWalletProvider(
  'fee brass payment tiny edge spoon control trophy provide rather harbor course',
  'https://rinkeby.infura.io/v3/53ed6ca9c43446a98fb1f9f799d2ca8f'
)

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(interface))
    .deploy({
      data: bytecode,
      arguments: ['hello there!'],
    })
    .send({ gas: '1000000', from: accounts[0] })

  console.log('Contract deployed to:' + result.options.address)
  provider.engine.stop()
}
deploy()

改变这个：

.deploy({
  data: bytecode,
  arguments: ['hello there!'],
})

到：

  .deploy({ data: "0x" + bytecode, arguments: ['hello there!'] })
  .send({ from: accounts[0], gas: "1000000" });
