Question

我有这样的问题。我是以太坊固态开发的新手，我创建了一个小型智能合约。

这是我的合同。

pragma solidity ^0.4.17;

contract Inbox{
    string public message;

    function Inbox(string initialMessage) public{
        message  = initialMessage;
    }

    function setMessage(string newMessage) public {
        message= newMessage;
    }
}

使用Nodejs将其部署到以太坊rinkeby测试网络中。我已经将JavaScript文件创建为compile.js和deploy.js。在这里，我分别提供了这些文件。

const path = require('path');
const fs = require('fs');
const solc = require('solc');

const inboxPath = path.resolve(__dirname, 'contracts','Inbox.sol'); 
const source = fs.readFileSync(inboxPath,'utf8');

module.exports = solc.compile(source,1).contracts[':Inbox'];

这是我的deploy.js文件

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

const provider = new HDWalletProvider(
    'my newmonic',
    'https://rinkeby.infura.io/v3/mykey'
);

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: ['Hi there!']})
        .send({ gas: '700000', from: accounts[0]});

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

当我点击节点deploy.js时，它给了我这样的错误。

Attempting to deploy from account #myaccount

我进行了大量搜索以找到解决此问题的方法。但是我找不到适合该问题的解决方案。

使用nodejs进行部署是否正确？
