Cannot find module 'hardhat-deploy' error

[FriedChicken777]

Not sure which code or what is causing this issue but getting "Error: Cannot find module 'hardhat-deploy'" when running
"yarn hardhat test".

Can someone please provide some guidance? Let me know if I need to provide anything else.

$ yarn hardhat test
yarn run v1.22.19

@FriedChicken777 Run these commands;

npm install -D hardhat-deploy

npm install --save-dev  @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers ethers

add this in hardhat config file;

require('hardhat-deploy');

Thanks @alymurtazamemon .
I was able to progress further. However, I am getting this error now.

It looks to be the same error in this discussion #4792
I tried to run these command but still getting the same error:
npm install --save-dev @nomiclabs/hardhat-ethers 'ethers@^5.0.0'
npm install --save-dev @nomiclabs/hardhat-ethers@npm:hardhat-deploy-ethers

I was able to resolve this by adding in hardhat config file.
require("@nomiclabs/hardhat-ethers")
