Solidity 智能合约迁移错误的 Truffle 和 Ganache 教程

Question

Following the tutorial on "Ethereum Development Walkthrough (Part 2: Truffle, Ganache, Geth and Mist)" I've, in broad strokes, initialized the truffle folder, copied over the Wrestling.sol , ran compile truffle , and, yet, after running migrate am not seeing any message about deploying the contract from ganache .

Each step has seemingly been completed correctly:

but perhaps either a step was skipped or done incorrectly?

Answer 1

You need to move the Wrestling.sol to the contracts folder. And to create the deployment JS code.

---

As the tutorial says:

Then copy the Wrestling.sol file from the last tutorial, into the folder “contracts”.

Next, open the folder “migrations” and create a new file named “2_deploy_contracts.js”. Migrations are simply scripts that'll help us deploy our contracts to a blockchain.

Paste the following code inside, and save.

 const Wrestling = artifacts.require("./Wrestling.sol") module.exports = function(deployer) { deployer.deploy(Wrestling); };
