var web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
var accounts_list = web3.eth.accounts;
var code = fs.readFileSync('Voting.sol').toString();
var compiledCode = solc.compile(code);
var abiDefinition = JSON.parse(compiledCode.contracts[':Voting'].interface)
var VotingContract = web3.eth.contract(abiDefinition)
var byteCode = compiledCode.contracts[':Voting'].bytecode
var deployedContract = VotingContract.new(['Itachi','Luffy','Midoriya'],{data: byteCode, from: web3.eth.accounts[0], gas: 4700000})
var deployedContractAddress = deployedContract.address;
var contractInstance = VotingContract.at(deployedContract.address);
// contractInstance.voteForCandidate('Itachi', {from: web3.eth.accounts[0]}) // function to vote for Itachi
// contractInstance.totalVotesFor.call('Itachi').toLocaleString() // function to return Itachi's votes
var deployedAddress = contractInstance.address;
console.log(contractInstance.address);
输出为:undefined
但是当我在节点控制台上手动运行每个命令时,情况并非如此。当我尝试typeof contractInstance.address
时,它输出为“字符串”
但我不想每次都手动运行每个命令,因此尝试在脚本中运行它

根据文档,如果您同步部署合约,则函数会立即返回事务散列,但您需要轮询事务的状态,直到它被挖掘。(只有这样,合同的地址才可用。)
作为替代方案,您可以异步部署合约:
