Blockchain 无法使用Truffle控制台运行smartContract。获取错误

我正在尝试运行以下智能合约：

pragma solidity ^0.5.0;

contract Calculator{
        function addition(uint a, uint b) public pure returns(uint) {
                return (a + b);
        }

        function substraction(uint a, uint b) public pure returns(uint) {
                return (a - b);
        }

        function multiplication(uint a, uint b) public pure returns(uint) {
                return ( a * b);
        }

        function division (uint a, uint b) public pure returns(uint) {
                return (a / b);
        }
}

当我尝试使用truffle控制台运行智能合约时，它错误地指出“汽油资金不足”

知道为什么吗？或者你能给我一些关于如何让它工作的想法吗。我尝试过多次增加气体限制，但没有任何帮助。

气体属性定义每个事务发送的气体量。瓦斯含量很高。事务处理的总值为gas*gasPrice。因此，您在部署/发送期间默认发送16000000000 gwei（160以太）。若您使用一些测试客户端作为ganache，那个么测试地址的基本金额是每个帐户100以太

我尝试将合同部署到标准设置（天然气：6700000）上，一切都很好。在配置示例中，gas在部署期间超过了块限制。如果您以某种方式成功部署，这意味着您的“live env”配置允许这样的气体限制。EVM将剩余的tx气体返回给您，但在您的情况下，发送该气体太多

sudo truffle console
