solidity - 错误：尚未将 SimpleSmartContract 部署到检测到的网络（网络/工件不匹配）

问题描述

我开发了一个简单的智能合约。当我运行松露测试时，它显示以下错误：我是新手，所以我无法弄清楚。

PS F:\pracdap> 松露测试

坚固性代码

pragma solidity >=0.4.22 <0.9.0;

contract SimpleSmartContract {
}

节点.js。测试代码

const SimpleSmartContract = artifacts.require('SimpleSmartContract');

contract('SimpleSmartContract', () => {
    it('should be deployed', async () => {
        const simpleSmartContract = await SimpleSmartContract.deployed();
        assert(simpleSmartContract.address !== '');
    });
});

解决方案

看起来您还没有为您的SimpleSmartContract. 2_deploy_contracts.js在 Migrations 目录中创建一个名为的文件。在其中添加以下代码：

    const SimpleSmartContract = artifacts.require("SimpleSmartContract");
    
    module.exports = 功能（部署者）{
      deployer.deploy(SimpleSmartContract);
    };

然后尝试运行测试。
