将智能合约部署到 PoA 私有以太坊区块链中出现错误：0x0 交易已挖掘但执行失败

Question

将智能合约部署到 PoA 共识以太坊私链时，总是会出现错误：“0x0 交易已挖掘，但执行失败”。检查区块信息后发现，由于gas耗尽，部署失败。即使调整了

gasLimit

，部署仍然失败。

和智能合约：

// SPDX-License-Identifier: GPL-3.0
pragma solidity ^0.8.0;

contract Simple {
    function getValue() public pure returns (string memory) {
        return "Hello, World!";
    }
}

考虑到可能是EVM的原因，在Remix中更改Solidity编译器版本后合约部署成功。由于Geth在1.14.x之后的版本不再支持PoA，因此使用Geth 1.13.15部署PoA私链，最高支持Solidity 0.8.19。
