【英文标题】：Truffle and Ganache tutorial for a Solidity smart contract migration error

【发布时间】：2021-07-11 00:02:20

【问题描述】：

按照“以太坊开发演练（第 2 部分：Truffle、Ganache、Geth 和 Mist）”教程，我粗略地初始化了 truffle 文件夹，复制到 Wrestling.sol，运行 compile truffle ，但是，在运行 migrate 之后，我没有看到任何关于从 ganache 部署合同的消息。

每个步骤似乎都已正确完成：

但可能是某个步骤被跳过或执行不正确？

【参考方案1】：

您需要将Wrestling.sol 移动到contracts 文件夹。并创建部署JS代码。

---

正如tutorial 所说：

然后将上一教程中的 Wrestling.sol 文件复制到“contracts”文件夹中。

接下来，打开文件夹“migrations”并创建一个名为“2_deploy_contracts.js”的新文件。迁移只是帮助我们将合约部署到区块链的脚本。

将以下代码粘贴进去，然后保存。

const Wrestling = artifacts.require("./Wrestling.sol")

module.exports = function(deployer) 
  deployer.deploy(Wrestling);
;
