Мой файл Solidity (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);
  }
}

Файл My Migration 1_initial_migration.js

var Migrations = artifacts.require("./Migrations.sol");

module.exports = function(deployer) {
  deployer.deploy(Migrations);
};

Answer 1

Удалите из функции конструктора параметр «Миграции», который нигде не используется.Это работает, когда я убираю аргумент "Миграции".Используйте как показано ниже:

constructor() public {
    owner = msg.sender;
  }
