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);
};
