我看了另一个"没有气体" SO帖子,他们还没有解决我的问题。 我正在使用ganache-cli开始
ganache-cli --account="0xce2ddf7d4509856c2b7256d002c004db6e34eeb19b37cee04f7b493d2b89306d, 2000000000000000000000000000000"
然后我执行
truffle migrate --reset
返回错误
Error encountered, bailing. Network state unknown. Review successful transactions manually.
Error: VM Exception while processing transaction: out of gas
(完整错误在最后) 这些是涉及的文件;
truffle.js
module.exports = {
networks: {
development: {
host: "localhost",
port: 8545,
network_id: "*",
gas: 470000
}
}
};
1_initial_migration.js
var Migrations = artifacts.require("./Migrations.sol");
module.exports = function(deployer) {
deployer.deploy(Migrations, {gas: 4500000});
};
2_deploy_contracts.js
var Voting = artifacts.require("./Voting.sol");
module.exports = function(deployer){
deployer.deploy(Voting, ['Rama', 'Nick', 'Jose'], {gas: 290000});
}
Voting.sol
pragma solidity ^0.4.18;
contract Voting {
mapping (bytes32 => uint8) public votesReceived;
bytes32[] public candidateList;
function Voting(bytes32[] candidateNames) public {
candidateList = candidateNames;
}
function totalVotesFor(bytes32 candidate) view public returns (uint8) {
require(validCandidate(candidate));
return votesReceived[candidate];
}
function voteForCandidate(bytes32 candidate) public {
require(validCandidate(candidate));
votesReceived[candidate] += 1;
}
function validCandidate(bytes32 candidate) view public returns (bool) {
for(uint i = 0; i < candidateList.length; i++) {
if (candidateList[i] == candidate) {
return true;
}
}
return false;

答案 0 :(得分:3)
错误消息是正确的。你没有为合同创造发送足够的天然气。
部署合同时,将为部署的3个不同阶段消耗燃气:
solc --optimize Voting.sol --bin-runtime -o .
并查看生成的文件的大小。你的合同是1116字节(我使用的是solc版本0.4.19,因此.18的大小可能略有不同),这导致消耗了223,200个气体。总共有357,240气体,因此你的290,000限制太低(Rinkeby的实际合约消耗了351,640气体。再次,我认为小的差异是由于编译器版本输出的轻微差异。我'我不是100%肯定这一点,但差异足够小 - 实际上是28字节的合同代码 - 我没有深入挖掘以找到根本原因。)
关于HackerNoon的一篇很好的文章,通过一个例子详细介绍了每个计算。
答案 1 :(得分:2)
如果其他人遇到错误:
Error encountered, bailing. Network state unknown. Review successful transactions manually.
Error: VM Exception while processing transaction: out of gas
删除./build
目录并在truffle.js
中启用solc优化器:
module.exports = {
networks: {
development: {
host: "localhost",
port: 8545, // Using ganache as development network
network_id: "*",
gas: 4698712,
gasPrice: 25000000000
}
},
solc: {
optimizer: {
enabled: true,
runs: 200
}
}
};
答案 2 :(得分:0)
我遇到了同样的问题,现在已经解决了。
运行时:VM出现故障时有两种情况-
使用truffle migrate --reset
添加-
solc: {
optimizer: {
enabled: true,
runs: 200
}
}
在Windows中的truffle.js
和Mac中的truffle-config.js
还请在networks->development
中给gasPrice和gasLimit较高,并确保与之匹配 ganache-cli
(如果使用)
当合同在remix
上运行正常,但在Runtime
上运行truffle
时,这是面临的最常见错误
使用web3
时,它使用的默认气体为90000,并且某些呼叫失败。因此,每当您发送交易时,请记住要提供足够的电量。
