我正在尝试使用松露的HDWalletProvider和Infura连接生成Rinkeby网络的合同,以生成提供程序,但是该合同似乎没有部署。
我收到此错误:
(node:14124) UnhandledPromiseRejectionWarning: TypeError: Cannot read property '0' of undefined
at deploy (C:\Users\user\Desktop\ethereum\lottery\deploy.js:16:62)

(node:14124) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)
(node:14124) [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.
这是我的部署脚本:
const HDWalletProvider = require('truffle-hdwallet-provider');
const Web3 = require('web3')
const { interface, bytecode } = require('./compile');
const provider = new HDWalletProvider(
ACCOUNT_MNEMONIC,
'https://rinkeby.infura.io/v3/' + INFURA_RINKEBY_TOKEN
);
const web3 = new Web3(provider);
const deploy = async () => {
const acccounts = 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})
.send({ from: acccounts[0], gas: '1000000' });
console.log(interface);
console.log('Contract deployed to', result.options.address);
};
deploy();
