编译@openzeppelin/contracts/utils/EnumerableSet.sol合约提示InternalCompilerError: Conversion from rational numbers to address types is not supported

您好，感谢反馈哈，问题正在排查，有进展了及时回复您，我们有PlatON开发者群，您也可以加我微信18657117189。
是不是合约源码里面对空地址的判断是0x0的格式？
在platon网络中的空地址是lat1qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq542u6a
这个合约引用到openzeppelin/contracts/utils/EnumerableSet.sol ，
上面address(0),在alaya测试网我把它改成address(atp1qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq542u6a) 编译提示Undeclared identifier.
下面是开源挖矿项目合约：
得加个字符串呀，address(“atp1qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq542u6a”)
有点麻烦哦，我把openzeppelin/contracts/token/ERC20/ERC20.sol 库里address(0) 改成 address(“atp1qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq542u6a”)
编译也遇到问题，感觉合约如果有引入openzeppelin库的项目，就不好办了。
address(uint160(0))
thanks, very much!
alaya-truffle migrations ,使用@openzeppelin/truffle-upgrades 提示truffle 版本太低：Global Truffle config not found: Truffle >=5.1.35 is required. Truffle exec not yet supported，这个要怎么办？
When I deploy upgradeable contracts , encountered this bug, how can I deploy upgradeable contracts by using @openzeppelin/truffle-upgrades on alaya network(alaya-truffle)
这个功能我没有用过
你这个合约的源码可以看下吗？
用@openzeppelin/truffle-upgrades测试部署合约Box.sol
// contracts/Box.sol
// SPDX-License-Identifier: MIT
pragma solidity ^0.6.12;
contract Box {
uint256 private value;
// Emitted when the stored value changes
event ValueChanged(uint256 newValue);
// Stores a new value in the contract
function store(uint256 newValue) public {
value = newValue;
emit ValueChanged(newValue);
}
// Reads the last stored value
function retrieve() public view returns (uint256) {
return value;
}
}
部署js 2_deploy_box.js
// migrations/2_deploy_box.js
const Box = artifacts.require('Box');
const { deployProxy } = require('@openzeppelin/truffle-upgrades');
module.exports = async function (deployer) {
await deployProxy(Box, [42], { deployer, initializer: 'store' });
};
这部分的部署可升级合约的功能我们需要做一些适配，感谢您的反馈，我们评估后后续考虑支持该功能
看一下truffle-config.js呢
