无法 运行 使用 Truffle 控制台的智能合约。出现错误
Unable to run the smartContract using Truffle Console. Getting error
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 运行 使用 truffle 控制台的智能合约时，它错误地指出“gas 资金不足”
sudo truffle console
truffle(development)> Calculator.deployed().then(function(instance) { app = instance;})
undefined
truffle(development)> app.multiplication(5, 5, {from: web3.eth.accounts[0]});
Uncaught:
Error: Returned error: err: insufficient funds for gas * price + value (supplied gas 25000000)

truffle(development)>
在我的松露-config.js 文件中：
networks: {
// Useful for testing. The `development` name is special - truffle uses it by default
// if it's defined here and no other network is specified at the command line.
// You should run a client (like ganache-cli, geth or parity) in a separate terminal
// tab if you use this network and you must also set the `host`, `port` and `network_id`
// options below to some value.
//
development: {
host: "127.0.0.1", // Localhost (default: none)
port: 8545, // Standard Ethereum port (default: none)
network_id: "*", // Any network (default: none)
},
live: {
network_id: 2020,
host: "127.0.0.1",
port: 8545,
from: "0x79b10CF39809f29160197ecbBdb21635684B0E45",
gas: 8000000000,
gasPrice: 20000000000
},
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？我多次尝试提高气体限制，但没有任何帮助。
Gas 属性 定义每笔交易发送多少 gas。气体限制非常高。交易的总价值是 gas * gasPrice。所以你在部署/tx 期间默认发送 160000000000 gwei（160 以太币）。如果你使用一些测试客户端作为 ganache，测试地址的基本数量是每个账户 100 以太币。
我尝试在标准设置（gas：6700000）上部署合约，一切正常。使用您的配置示例，gas 在部署期间超过了块限制。如果您以某种方式成功部署，则意味着您的 'live env' 配置允许这样的 gas 限制。 EVM returns 剩余的 tx gas 给你，但在你的情况下发送它太多了。
