我的 Solidity 文件(Migration.sol)
pragma solidity ^0.4.17;
contract Migrations {
address public owner;
uint public last_completed_migration;
modifier restricted() {
if (msg.sender == owner) _;
}
constructor(Migrations) 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);
}
}
我的遷移文件 1_initial_migration.js
var Migrations = artifacts.require("./Migrations.sol");
module.exports = function(deployer) {
deployer.deploy(Migrations);
};
松露版本松露 v4.1.11(核心:4.1.11)Solidity v0.4.24(solc-js)
移除構造函數參數“Migrations”,該參數在任何地方都不使用。 當我刪除“遷移”參數時它正在工作。 使用如下:
constructor() public {
owner = msg.sender;
}
如果在 Ganache 上更改為 Instabul 或更改您所在的 CHAIN
