使用 truffle 迁移带有继承的合同时出错

Question

我在尝试迁移具有继承的合同时遇到此错误

错误：“NFTCollectible”--“未定义”的参数数量无效。得到 0 预期 1!.

/contracts/NFTCollectible.sol

pragma solidity ^0.8.0;

import "@openzeppelin/contracts/utils/Counters.sol";
import "@openzeppelin/contracts/access/Ownable.sol";
import "@openzeppelin/contracts/utils/math/SafeMath.sol";
import "@openzeppelin/contracts/token/ERC721/extensions/ERC721Enumerable.sol";

contract NFTCollectible is ERC721Enumerable, Ownable {
        using SafeMath for uint256;
        using Counters for Counters.Counter;
        ...    
    }

/migrations/2_deploy_contracts.js

var NFTCollectible = artifacts.require("NFTCollectible");

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

Answer 1

这是页面上的 NFTCollectible 合约：

所以这个合约有一个构造函数方法，它需要 1 个参数。所以当你部署合约时，你必须将参数传递给合约，如下所示：

var NFTCollectible = artifacts.require("NFTCollectible");

module.exports = function(deployer) {
    // you have to pass the baseURI
    deployer.deploy(NFTCollectible,"https://baseUriHere");
};
