解析器错误 ERC721

Question

我在解决这个问题时遇到了麻烦。 来自solidity: ParserError: Expected '{' but got identifier --> Mint.sol:1443:16: | 第1443章合同八位开国元勋是ERC721A，可拥有，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"){}

Answer 1

您的智能合约名称不应在单词之间有空格。 另一个问题是关闭的EightFoundingFathers智能合约缺少一个“}”。 我以这种方式调整了您的智能合约代码：

// 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"){

  }
}
