如何在truffle迁移脚本中使用truffle部署程序嵌套promises

npm install -g truffle

const MyContract = artifacts.require("MyContract");

module.exports = async function(deployer) {
  // 部署第一个合约
  await deployer.deploy(FirstContract);
  const firstContract = await FirstContract.deployed();

  // 部署第二个合约
  await deployer.deploy(SecondContract);
  const secondContract = await SecondContract.deployed();

  // 部署第三个合约，并传递第一个和第二个合约的地址作为参数
  await deployer.deploy(ThirdContract, firstContract.address, secondContract.address);
  const thirdContract = await ThirdContract.deployed();

  // 其他操作...
};

const MyContract = artifacts.require("MyContract");

module.exports = function(deployer) {
  deployer.deploy(FirstContract)
    .then(function() {
      return FirstContract.deployed();
    })
    .then(function(firstContract) {
      // 部署第一个合约完成，可以进行其他操作

      return deployer.deploy(SecondContract);
    })
    .then(function() {
      return SecondContract.deployed();
    })
    .then(function(secondContract) {
      // 部署第二个合约完成，可以进行其他操作

      return deployer.deploy(ThirdContract, firstContract.address, secondContract.address);
    })
    .then(function() {
      return ThirdContract.deployed();
    })
    .then(function(thirdContract) {
      // 部署第三个合约完成，可以进行其他操作

      // 其他操作...
    });
};
