//const web3 = new Web3(provider);

const provider = new HDWalletProvider(
  "[12 word mnemonic]",
  "[rinkeby api from infura]"
);

const web3 = new Web3(provider);

const deploy = async () => {
  const accounts = await web3.eth.getAccounts();

  console.log("Attempting to deply 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(interface);
  console.log("Contract deployed to", result.options.address);
};
deploy();

当我运行时 …
