我正在尝试在Ropsten网络上部署测试合同。我正在使用metamask,infura和松露创建和测试合同。我的文件夹结构看起来像这样
我的迁移文件具有以下代码
const TestContract = artifacts.require("TestContract");
module.exports = function(deployer) {
deployer.deploy(TestContract);
};
当我运行松露迁移时,出现以下错误 找不到任何来源的迁移工件
我的truffle-config.js看起来像这样
const HDWalletProvider = require('truffle-hdwallet-provider')
module.exports = {
networks: {
ropsten: {
provider: function() {
return new HDWalletProvider("Mnemonic key", "https://ropsten.infura.io/v3/API_KEY")
},
network_id: 3,
gas: 4000000
}
},
contracts_directory: './src/contracts/',
contracts_build_directory: './src/abis/',
compilers: {
solc: {
optimizer: {
enabled: true,
runs: 200
}
}
}
}
答案 0 :(得分:0)
您需要在合同文件夹中拥有Migrations
合同:
pragma solidity >=0.4.25 <0.6.0;
contract Migrations {
address public owner;
uint public last_completed_migration;
modifier restricted() {
if (msg.sender == owner) _;
}
constructor() public {
owner = msg.sender;
}
function setCompleted(uint completed) public restricted {
last_completed_migration = completed;
}
function upgrade(address new_address) public restricted {
Migrations upgraded = Migrations(new_address);
upgraded.setCompleted(last_completed_migration);
}
}
您的迁移文件夹中还有一个1_initial_migration.js
:
const Migrations = artifacts.require("Migrations");
module.exports = function(deployer) {
deployer.deploy(Migrations);
};
