TypeError:从地址到应付款地址的隐式转换无效

Question

大家好啊！

我正在为我的ERC-721智能合同增加版税。我的目标是每当有人制造一个新的标记或转让一个令牌时，将版税返还给艺术家。

然而，现在当我试图迁移我的合同时，我得到了一个错误。

TypeError: Invalid type for argument in function call. Invalid implicit conversion from address to address payable requested

           setRoyalties(_tokenIdTracker.current(),devAddress,2000);
                                                  ^^^^^^^^^

这是我的合同

        setRoyalties(_tokenIdTracker.current(),artistAddress,2000);
        _tokenIdTracker.increment();
    }


    function setRoyalties(uint _tokenId, address payable _royaltiesReceipientAddress, uint96 _percentageBasisPoints) public onlyOwner {
        LibPart.Part[] memory _royalties = new LibPart.Part[](1);
        _royalties[0].value = _percentageBasisPoints;
        _royalties[0].account = _royaltiesReceipientAddress;
        _saveRoyalties(_tokenId, _royalties);
    }

    function royaltyInfo(uint256 _tokenId, uint256 _salePrice) external view returns (address receiver, uint256 royaltyAmount) {
        LibPart.Part[] memory _royalties = royalties[_tokenId];
        if(_royalties.length > 0) {
            return (_royalties[0].account, (_salePrice * _royalties[0].value)/10000);
        }
        return (address(0), 0);
    }
    

}

我使用EpicEagles合同作为参考智能合同代码，他们似乎在做类似的事情，我可能错过了一个步骤。如有任何帮助将不胜感激，谢谢。

我试过的是：

• 地址应付常数artistAddress = 0xcBC0x0x0x0x0x0x0x0；

您的调用是将devAddress发送到setRoyalties方法，该方法期望它的位置是address payable _royaltiesReceipientAddress。由于它期望函数上有一个paybale地址，所以必须在它转到方法之前转换它，因此可以在调用函数时将其转换为payable：

setRoyalties(_tokenIdTracker.current(),payable(devAddress),2000);
