解析器錯誤 ERC721

Question

我在解決這個問題時遇到了麻煩。 來自solidity: ParserError: Expected '{' but got identifier --> Mint.sol:1443:16: | 第1443章合同八位開國元勛是ERC721A，可擁有，ReentrancyGuard { | ^^^^^^^^

//below is my code//

line 1443 ignore this// 
contract Eight Founding Fathers is ERC721A, Ownable, ReentrancyGuard {

  string public        baseURI;
  uint public          price             = 0.003 ether;
  uint public          maxPerTx          = 20;
  uint public          totalFree         = 1000;
  uint public          maxSupply         = 1776;
  uint256 public       maxFreePerWallet = 3;
  bool public          mintEnabled;
  mapping(address => uint256) private _mintedFreeAmount;

  constructor() ERC721A("8Bit Founding Fathers","8BFF"){}

您的智能合約名稱不應在單詞之間有空格。 另一個問題是關閉的EightFoundingFathers智能合約缺少一個“}”。 我以這種方式調整了您的智能合約代碼：

// SPDX-License-Identifier: GPL-3.0
pragma solidity >=0.7.0 <0.9.0;

contract EightFoundingFathers is ERC721A, Ownable, ReentrancyGuard {

  string public        baseURI;
  uint public          price             = 0.003 ether;
  uint public          maxPerTx          = 20;
  uint public          totalFree         = 1000;
  uint public          maxSupply         = 1776;
  uint256 public       maxFreePerWallet = 3;
  bool public          mintEnabled;
  mapping(address => uint256) private _mintedFreeAmount;

  constructor() ERC721A("8Bit Founding Fathers","8BFF"){

  }
}
