迁移用完了

Question

我正在使用Ganache。我开箱了宠物商店。然后在合同文件夹中，制作了一个文件Election.sol，其中包含代码

pragma solidity ^0.5.8;  

contract Election{
    string public candidate;
    constructor() public{
        candidate = "candidate 1"; //state var

    }   
}

然后在migrations文件夹中，制作了2_deploy_contract.js，其中包含代码

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

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

当我使用命令-truffle migrate进行松露迁移时，会出现此错误。

Compiling your contracts...
Everything is up to date, there is nothing to compile.

Migrations dry-run (simulation)

我已经看到一些解决类似问题的解决方案，但是它不能解决我的问题。
