Hardhat deploy script

[Aggregator2]

I'm working on a Hardhat project and encountering:

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

This happens when I run my deploy.js script. The error occurs at the line:

const amount = ethers.utils.parseEther("1.0");

I have this at the top of the file:

const { ethers } = require("hardhat");

But ethers still seems to be undefined.

---

System:

• Hardhat v2.22.0
• Node.js 18
• Windows 11
• Running npx hardhat node

Other parts of the script like getSigners() and contract deployment work fine. I’ve tried reinstalling Hardhat, using require("ethers") instead, and restarting VS Code — but no change.

Full error:

const amount = ethers.utils.parseEther("1.0"); // 1 ETH in wei
                            ^

Hey @Aggregator2, could you check that you have the hardhat-ethers plugin installed and included in your hardhat.config.{js,ts}:

https://hardhat.org/hardhat-runner/plugins/nomicfoundation-hardhat-ethers#installation

The missing connection is the most likely reason that ethers is undefined when you import it.
