zeppelinSales 合約建構子預期 3 個參數,收到 0
我正在嘗試部署 Crowdsale 契約,但是當我執行“truffle migrate –network ropsten”時,我得到了這些錯誤:

這是我的 2_deploy_contracts.js
const zeppelinSales = artifacts.require("./zeppelinSales.sol"); module.exports = function(deployer) { deployer.deploy(zeppelinSales); };
這是 1_initial_migration.js
var Migrations = artifacts.require("./Migrations.sol"); module.exports = function(deployer) { deployer.deploy(Migrations); };
這是 migrations.sol pragma solidity ^0.4.23;
contract Migrations { address public owner; uint public last_completed_migration; constructor() public { owner = msg.sender; } modifier restricted() { if (msg.sender == owner) _; } 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); } }
提前致謝!
的建構子
ZeppelinSales
接受三個參數:constructor(uint256 _rate, address _wallet, ERC20 _token) public
但是您的遷移腳本沒有提供它們:
const zeppelinSales = artifacts.require("./zeppelinSales.sol"); module.exports = function(deployer) { deployer.deploy(zeppelinSales); };
您需要提供函式
_rate
、_wallet
地址和_token
地址。deployer.deploy
一個例子:
let rate = <INSERT THE RATE HERE>; // a number let wallet = "<INSERT THE WALLET ADDRESS HERE>"; // an address string let token = "<INSERT THE ERC20 TOKEN ADDRESS HERE>"; // an address string const zeppelinSales = artifacts.require("./zeppelinSales.sol"); module.exports = function(deployer) { deployer.deploy(zeppelinSales, rate, wallet, token); };
