【问题描述】：

松露迁移使用网络“开发”。

Running migration: 1_initial_migration.js   Deploying Migrations...
Error encountered, bailing. Network state unknown. Review successful
transactions manually. Error: Migrations contract constructor expected
1 arguments, received 0
    at /usr/local/lib/node_modules/truffle/build/webpack:/~/truffle-contract/contract.js:390:1

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);
  }
}

我的迁移文件 1_initial_migration.js

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

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

【解决方案1】：

删除构造函数参数“Migrations”，它在任何地方都没有使用。当我删除“迁移”参数时它正在工作。如下使用：

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

如果在 Ganache 上更改为 Instabul 或更改您所在的 CHAIN
