使用部署-zksync尝试部署智能契约时出错

Question

在运行yarn hardhat deploy-zksync后，我得到了以下错误：

Running deploy script for the Greeter contract
An unexpected error occurred:

error Command failed with exit code 1.

deploy.ts脚本的代码如下：

import { Wallet, utils } from "zksync-web3";
import * as ethers from "ethers";
import { HardhatRuntimeEnvironment } from "hardhat/types";
import { Deployer } from "@matterlabs/hardhat-zksync-deploy";

// An example of a deploy script that will deploy and call a simple contract.
export default async function (hre: HardhatRuntimeEnvironment) {
  console.log(`Running deploy script for the Greeter contract`);

  // Initialize the wallet.
  const wallet = new Wallet("");

  // Create deployer object and load the artifact of the contract you want to deploy.
  const deployer = new Deployer(hre, wallet);
  const artifact = await deployer.loadArtifact("Greeter");

  // Estimate contract deployment fee
  const greeting = "Hi there!";
  const deploymentFee = await deployer.estimateDeployFee(artifact, [greeting]);

  // Deploy this contract. The returned object will be of a `Contract` type, similarly to ones in `ethers`.
  // `greeting` is an argument for contract constructor.
  const parsedFee = ethers.utils.formatEther(deploymentFee.toString());
  console.log(`The deployment is estimated to cost ${parsedFee} ETH`);

  const greeterContract = await deployer.deploy(artifact, [greeting]);

  //obtain the Constructor Arguments
  console.log("constructor args:" + greeterContract.interface.encodeDeploy([greeting]));

  // Show the contract info.
  const contractAddress = greeterContract.address;
  console.log(`${artifact.contractName} was deployed to ${contractAddress}`);
}

该错误通常会返回，因为您试图部署的字节码对zkSync无效。您是否安装并配置了hardhat-zksync-solc插件，并使用它编译了契约？见这里的文件

检查您是否有一个artifacts-zk文件夹(这是在用zksolc编译后创建的)，还检查您的契约JSON文件中生成的字节码(包含契约ABI的相同文件)是否为空。

我们发现了一些操作系统的问题，并发布了一个修复程序。确保您在hardhat.config.ts文件中使用zksolc版本的D4(或更高版本)，并使用@matterlabs/hardhat-zksync-solc版本0.3.15 (或更高版本)。
