false 交易已挖掘，但在 Remix IDE 中执行失败

Question

我从合约中的构造函数中收到 false Transaction mined butexecution failed 错误。我只是将部署合约的地址保存在经理变量中，而不是向该帐户发送任何资金。

   // SPDX-License-Identifier: GPL-3.0

pragma solidity ^0.8.20;

contract Lottery{
    address public manager;
    address[] public players;

    constructor() public {
        manager = msg.sender;
    }

    function enter()public payable{
        require(msg.value > 0.1 ether);
        players.push(msg.sender);
    }

//Random number generator function.
    function random()private view returns (uint){
        return uint(keccak256(abi.encodePacked(block.difficulty, block.timestamp, players)));
    }

    function pickWinner()public{
        uint index = random() % players.length;
        address contractAddress = address(this);
        payable(players[index]).transfer(contractAddress.balance);
    }

}

在solidity v0.7之后，它说不需要构造函数的可见性，所以我尝试删除

public

可见性。我也尝试使用

payable

可见性

constructor()

但仍然遇到相同的错误。

Answer 1

确保evm（以太坊虚拟机）版本和VM（虚拟机）/环境相同。

Answer 2

这种情况下的常见检查点是确保VM（虚拟机）/环境和EVM（以太坊虚拟机）版本应该相同。

Answer 3

试试下面这个

// SPDX-License-Identifier: GPL-3.0
pragma solidity ^0.8.20;

contract Lottery {
    address public manager;
    address[] public players;

    constructor() {
        manager = msg.sender;
    }

    function enter() public payable {
        require(msg.value > 0.1 ether);
        players.push(msg.sender);
    }

    // Random number generator function.
    function random() private view returns (uint) {
        return uint(keccak256(abi.encodePacked(block.difficulty, block.timestamp, players)));
    }

    function pickWinner() public {
        uint index = random() % players.length;
        address payable winner = payable(players[index]);
        uint contractBalance = address(this).balance;
        winner.transfer(contractBalance);
        players = new address[](0); // Reset the player array for a new round
    }
}
