Lesson 9: Error: cannot find artifact "VRFCoordinatorV2Mock"

[Sugunaramkumar]

Hi, when deploying mocks it is showing " Error: cannot find artifact "VRFCoordinatorV2Mock", I have looked into the discussion #1093, but for me artifacts is creating, I have followed instructions there, I have deleted artifacts and cache many times and deployed again and again, but still error is coming. I have even created new project from gitclone(Patrick repo) and deployed it, still same error is coming. I do not know what I missed. Could someone help me? thanks

I have created a repo in git of my current code with error, below is my link
https://github.com/Sugunaramkumar/Raffle-FCC.git

I am also attaching a error screenshot with error

In your contracts folder create a folder named test.In the test folder create a file named VRFCoordinatorV2Mock.sol.Inside this file add this:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "@chainlink/contracts/src/v0.8/mocks/VRFCoordinatorV2Mock.sol" ;

Run yarn hardhat deploy .This is what you are missing.Also next time put the .history file in .gitignore.It can take you a very long time to push a project to github

@Sugunaramkumar in your 01-deploy-raffle.js You are importing ethers from ethers.change it to this const {ethers}=require("hardhat") to get it from hardhat.The hardhat package also contains ethers

Thank you, it worked.

@Sugunaramkumar I have also realized you might experience a problem then deploying to rinkeby.You are suppossed to import verify function from utils not the helper-hardhat-config also this line is wrong

const { networks } = require("../hardhat.config") 

You are not supposed to import anything from hardhat.config.network (not networks) should be imported from hardhat.like this

const { network } = require("hardhat") 

I don't know why it didn't give an error.

Thank you again. I fixed all the above suggestions. It is deploying successfully.

Adding the test folder to the contracts folder helped me thanks!
