Parsererror ERC721

Question

我在解决这个问题时遇到了麻烦。 从坚固性： ParserError：预期'{'但有识别符 - ＆gt; Mint.Sol：1443：16： | 1443 |合同八个开国元勋是ERC721A | ^^^^^^^^

//below is my code//

contract Eight Founding Fathers is ERC721A, Ownable, ReentrancyGuard {

  string public        baseURI;
  uint public          price             = 0.003 ether;

您的智能合同名称不应在单词之间有空间。另一个问题是，对于八FUNDINGINGFATHERS智能合约缺少A'}'。
我以这种方式调整了您的智能合同代码：

// 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"){

  }
}
