Truffle migrate - TypeError: migrations.setCompleted 不是函式

我跑向$ npx truffle migrateGanache 部署 2 個合約，但出現錯誤：

This version of µWS is not compatible with your Node.js build:

Error: Cannot find module './uws_darwin_x64_88.node'
Falling back to a NodeJS implementation; performance may be degraded.

這是 1_initial_migration.js 中的程式碼

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

module.exports = function(deployer) {
 deployer.deploy(Migrations);
};

我正在學習，這是我第一次部署，所以我不確定如何修復錯誤。謝謝您的幫助！

在contracts目錄中，你應該有Migrations.sol，它的程式碼應該是這樣的：

// SPDX-License-Identifier: MIT
pragma solidity >=0.4.22 <0.9.0;

contract Migrations {
 address public owner = msg.sender;
 uint public last_completed_migration;

 modifier restricted() {
   require(
     msg.sender == owner,
     "This function is restricted to the contract's owner"
   );
   _;
 }
 // this might not be set correctly
 function setCompleted(uint completed) public restricted {
   last_completed_migration = completed;
 }
}
