Lesson 7(8:41:09): I am unable to deploy my SimpleStorage.sol Contract

[olaoyesalem]

const {ethers} = require("hardhat")

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

On this function , I am running into an error:

TypeError: Cannot read properties of undefined (reading 'getContractFactory')

Can someone tell me what's going on?

Hey @olaoyesalem since you are using hardhat-ethers rather than ethers itself, it might be causing the error you are experiencing. Try and replace hardhat with ethers in the line const {ethers} = require("hardhat") and see if it may resolve your issue

[olaoyesalem]

I tried this, but it still gave me the same error

In your hardhat.config.js file, adding this (along with other imports) should fix the problem:

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

Also, the only possibility besides this could be the naming scheme; please cross-check if it is SimpleStorage

[olaoyesalem]

Thank you.
After adding

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

to my hardhat.config.js, it worked

[krakxn]

All the best!

BTW, please mark the correct answer for others to refer to (either Ali's or mine if it worked, considering your reply to the above not working).

[olaoyesalem]

Yes, I have done that.

@olaoyesalem Make sure you have these dependencies:

{
  "name": "hardhat-simple-storage",
  "version": "1.0.0",
  "description": "",
  "scripts": {},
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "@nomiclabs/hardhat-ethers": "^2.0.6", // this one

you can copy/paste the entire and delete the node_modules folder and run npm i --force

I tried this also and it's already working.
