TypeError: secp.sign 在使用 ethereum-cryptography 库中的 secp256k1 时不是一个函数

Question

我正在关注 Alchemy Learn 的以太坊开发者训练营。我在自己的 JavaScript 环境中运行以下代码时遇到错误，该代码旨在使用私钥对消息进行签名。我正在使用

ethereum-cryptography

版本的

2.0.0

库。

// signMessage.js file
const secp = require("ethereum-cryptography/secp256k1");
const hashMessage = require("./hashMessage");

const PRIVATE_KEY = "some-key";

async function signMessage(msg) {
    const hash = hashMessage(msg);
    const sign = await secp.sign(hash, PRIVATE_KEY, { recovered: true });
    
    return sign;
}

module.exports = signMessage;

这是

test.js

文件：

const { assert } = require('chai');
const secp = require("ethereum-cryptography/secp256k1");
const { toHex } = require("ethereum-cryptography/utils");

const signMessage = require('./signMessage');
const hashMessage = require('./hashMessage');

const PRIVATE_KEY = "some-key";

describe('Sign Message', () => {
    it('should return both a signature and a recovery bit', async () => {
        const response = await signMessage('hello world');

        const errMessage = "expected signMessage to return both a signature and recovery bit!";
        assert(response.length, errMessage);
        assert(response.length === 2, errMessage);

        const [signature, recoveryBit] = response;
        assert(signature.length, "expected signature to be a Uint8Array");
        assert(typeof recoveryBit === "number", "expected the recovery bit to be a number");
    });

    it('should have been signed by the same private key', async () => {
        const [sig, recoveryBit] = await signMessage('hello world');
        const messageHash = hashMessage('hello world');
        const recovered = secp.recoverPublicKey(messageHash, sig, recoveryBit);

        const publicKey = secp.getPublicKey(PRIVATE_KEY);
        assert.equal(toHex(recovered), toHex(publicKey));
    });

});

然后，在终端上运行

yarn test

时，我得到：

yarn run v1.22.19
$ yarn mocha ./src/test.js
$ '/Users/user/alchemy/node_modules/.bin/mocha' ./src/test.js

  Sign Message
    1) should return both a signature and a recovery bit
    2) should have been signed by the same private key

  0 passing (6ms)
  2 failing

  1) Sign Message
       should return both a signature and a recovery bit:
     TypeError: secp.sign is not a function
      at signMessage (src/signMessage.js:11:29)
      at Context.<anonymous> (src/test.js:13:32)
      at process.processImmediate (node:internal/timers:478:21)

  2) Sign Message
       should have been signed by the same private key:
     TypeError: secp.sign is not a function
      at signMessage (src/signMessage.js:11:29)

在 Alchemy 在线环境中运行它时，它可以工作。我想知道问题是什么。希望有人能帮助我。
