Can't deploy my script

[alex81983]

When trying to deploy my script I run into the error "TypeError: Cannot read properties of undefined (reading 'getContractFactory')". I run "yarn hardhat run scripts/deploy.js --network goerli".

Below is my deploy.js code

// imports

const { ethers } = require("hardhat")

// async main
async function main() {
   const SimpleStorageFactory = await ethers.getContractFactory(
    "SimpleStorage"
    )
 
 console.log("Deploying contract...")
 const simpleStorage = await SimpleStorageFactory.deploy()
 await simpleStorage.deployed()
 }

// main
main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error)
    process.exit(1)
  })

@alex81983 Make sure you have ethers installed. If you already have then leave your repo link I will check it.

@alex81983 Make sure you add this in hardhat.config.js file

require("@nomiclabs/hardhat-waffle");

I added require("@nomiclabs/hardhat-waffle"); but when I ran scripts/deploy I got Error: Cannot find module '@nomiclabs/hardhat-waffle'

[alymurtazamemon]

@alex81983 Yes, it means it is not installed. run this command npm i --save-dev @nomiclabs/hardhat-waffle or yarn add --dev @nomiclabs/hardhat-waffle

Finally!! Yes yarn add --dev @nomiclabs/hardhat-waffle worked! Thanks so much
