Question

使用节点compile.js运行compile.js文件时遇到问题。我的代码：

const async = require('asyncawait/async');
const await = require('asyncawait/await');

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

const provider = new HDWalletProvider(
    'nut plug quality level uncle jeans retire guide eagle gossip cluster sudden',
    'https://rinkeby.infura.io/v3/37097b2064214600912ad8a746ff433a'
);

const web3 = new Webs(provider);

const deploy = async (() => {
    const accounts = await (web3.eth.Accounts());
    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: '1000000', from: accounts[0]})
    );

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

deploy();

运行后：节点compile.js

错误日志：

我做了分析，似乎“ const HDWalletProvider = require（'truffle-hdwallet-provider'）;”在/home/edureka/sankalp_practice/inbox/node_modules/eth-block-tracker/src/index.js中调用函数async awaitCurrentBlock（）。

所以请让我知道如何解决它。

您的依赖项使用看起来像节点8. *的“ async awaitCurrentBlock”，在这种情况下，您只是使用过旧的节点版本。您需要该依赖项，然后必须更新，但这将以另一种方式破坏您的代码->您要导入依赖项“ async”和“ await”，它们是节点8中的保留关键字，因此您必须更新语法也是如此

运行我的.js文件时异步awaitCurrentBlock（）中的意外标识符

运行后：节点compile.js
