Question

我正在尝试使用ERC 725创建身份智能合约，并在尝试编译它时遇到错误。最初，我试图在一个单独的实体文件中创建，但大多数时候我在尝试进行编译时都遇到导入错误。因此，我在基本ERC725.sol文件上执行此操作。我要在主合同之后的文件中添加我自己的合同。这是我试图添加的代码

enter code here

pragma solidity ^0.6.0;

// modules
import "./ERC725X.sol";
import "./ERC725Y.sol";

/**
 * @title ERC725 bundle
 * @dev Bundles ERC725X and ERC725Y together into one smart contract
 *
 *  @author Fabian Vogelsteller <fabian@lukso.network>
 */
contract ERC725 is ERC725X, ERC725Y  {

    /**
     * @notice Sets the owner of the contract
     * @param _newOwner the owner of the contract.
     */
    constructor(address _newOwner)
    ERC725X(_newOwner)
    ERC725Y(_newOwner)
    public {}

    // NOTE this implementation has not by default: receive() external payable {}
}


contract myERC725 is ERC725,ERC721{
    
    address public owner;
    mapping(uint => identity) identity_id;
    
    struct identity {
        
        string hash;
        string filename;
        
        uint aadhar_id;
        string name;
        uint160 age;
        string blood_group;
        
        string city;
        string state;
        string country;
        
        
    }
    
    identity id;
    
    constructor() ERC725("0x5B38Da6a701c568545dCfcB03FcB875f56beddC4") public{
        
        owner = msg.sender;
        
        
    }
    
    modifier isOwner() {

         require(msg.sender == owner, "Access is not allowed");

         _;
         
    }
    
    
function setDetails(uint _aadhar_id,string memory _name,uint160 _age,string memory _blood_group, string memory _city,string memory _state,string memory _country) public isOwner{
    
   _mint(msg.sender,_aadhar_id);
    
    id.name = _name;
    id.age = _age;
    id.blood_group = _blood_group;
    id.city = _city;
    id.state = _state;
    id.country = _country;
    identity_id[_aadhar_id]=id;
    
    
  
}


//function getFile(uint _index) public view returns(string memory,string)

function getDetails(uint _aadhar_id)public view returns(string memory _hash,string memory,uint160,string memory,string memory,string memory,string memory){
    
   
   identity memory id = identity_id[_aadhar_id];
   return(id.hash,id.name,id.age,id.blood_group,id.city,id.state,id.country);
   
  }


}

我得到的错误是：

浏览器/github/ERC725Alliance/ERC725/implementations/contracts/ERC725/ERC725.sol 声明错误：找不到标识符或标识符不唯一。我的ERC725合同是ERC725，ERC721 {..

我不确定我是否做对了。任何人都可以在这方面指导我。这对我有很大帮助。谢谢。

找不到标识符或唯一的-solidity编译错误
