类型错误：ethers.Wallet.fromEncryptedJsonSync 不是构造函数

Question

我正在尝试运行这段代码，以使用 ethers.js 库在 JS 中部署智能合约：

const ethers = require("ethers");
const fs = require("fs-extra");
require("dotenv").config();

async function main() {
  const provider = new ethers.ethers.JsonRpcProvider(process.env.RPC_URL);
  // reads the json private key from file
  const encryptedJson = fs.readFileSync("./.encryptedKey.json", "utf-8");
  
// ========= START FAILING PART ============
  let wallet = new ethers.Wallet.fromEncryptedJsonSync(
    encryptedJson,
    process.env.PRIVATE_KEY_PASSWORD
  );
// ========= END FAILING PART ============
  
  wallet = await wallet.connect(provider);
  const abi = fs.readFileSync("./SimpleStorage_sol_SimpleStorage.abi", "utf-8");
  const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf-8"
  );
  
  const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
  console.log("Deploying, please wait...");
  const contract = await contractFactory.deploy({ gasPrice: 1000000000000 });
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

但我不断在控制台中收到此错误：

TypeError: ethers.Wallet.fromEncryptedJsonSync is not a constructor
at main (/home/vituz01/hh/ethers-simple-storage/deploy.js:36:16)
at Object.<anonymous> (/home/vituz01/hh/ethers-simple-storage/deploy.js:90:1)

at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:84:12)
at node:internal/main/run_main_module:23:47

有人可以解释为什么会失败吗？我认为我正确调用了函数 fromEncryptedJsonSync() （如 EthersJS v5 文档中所述，请参阅以下链接：ethers.Wallet.fromEncryptedJsonSync）；我找不到 ethers.js v6 文档，因为他们仍在构建它。

删除 new 创建构造函数

let wallet = ethers.Wallet.fromEncryptedJsonSync(
  encryptedJson,
  process.env.PRIVATE_KEY_PASSWORD
);
