const HDWalletProvider = require('@truffle/hdwallet-provider'); const Web3 = require('web3'); const { abi, evm } = require('./compile'); console.log('abi',abi); provider = new HDWalletProvider( 'repeat place announce visit level double connect forest lens casual marble ladder', 'https://mainnet.infura.io/v3/6f9868010c6948b2acd01733b944fcac' ); 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(abi) .deploy({ data: evm.bytecode.object}) .send({ gas: '1000000', from: accounts[0] }); console.log('Contract deployed to', result.options.address); provider.engine.stop(); }; deploy();

Compilar.js

 const path = require('path'); const fs = require('fs'); const solcCompile.js = require('solc'); const contractPath = path.resolve(__dirname, 'contracts', 'Lottery.sol'); const source = fs.readFileSync(contractPath, 'utf8'); var input = { language: 'Solidity', sources: { 'Lottery.sol': { content: source } }, settings: { outputSelection: { '*': { '*': ['*'] } } } }; var output = JSON.parse(solc.compile(JSON.stringify(input))); console.log("THe output", output); var contract = output.contracts['Lottery.sol'].Lottery; //console.log("Contract", contract) var bytecode = contract.evm.bytecode.object; var interface = contract.abi; module.exports = {interface, bytecode};

Creé este código y ejecuté el comando node deployment.js y me dio este error "Error: debe proporcionar la interfaz JSON del contrato al crear una instancia de un objeto de contrato".

Y me muestra abi undefined no entendí como solucionar este error.
