[wilonweb]

Hello
I can't install yarn hadrhat
I make a folder hardhat-tutorial
after cd hardhat-tutorial
on it i launch yarn and yarn init

And When i launch yarn add --dev the console output is :

yarn add v1.22.19
warning package.json: No license field
error Missing list of packages to add to your project.
info Visit https://yarnpkg.com/en/docs/cli/add for documentation about this command.

and when i launch yarn hardhat
the output is :

yarn run v1.22.19
error Command "hardhat" not found.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

and this is my package.json file

{
  "name": "hard-hat-simple-storage-2",
  "version": "1.0.0",
  "license": "MIT",
  "devDependencies": {
    "@nomicfoundation/hardhat-toolbox": "^1.0.2",
    "hardhat": "^2.10.1"
  }
}

@NinjaTurtles-cloud you have hardhat in the package.json maybe its related dependencies are not installed correctly, try this remove node_modules folder, and run yarn install again.

So did it
And when i launch yarn install i got a lot of warning and 2 error

[2/4] Fetching packages...
error hardhat@2.10.1: The engine "node" is incompatible with this module. Expected version "^14.0.0 || ^16.0.0 || ^18.0.0". Got "15.14.0"
error Found incompatible module.

And i got always the same problem

I got this error too.You should reinstall node from node.js. website to get latest version.And can then do yarn remove hardhat to remove hardhat .And then do yarn add --dev hardhat to add it again .This should work.

I also encountered similar issue. That is why I went back to Lesson 5 to re-learn how to install 'yarn' and to no avail (still). Appreciate your help here please.

Try:

1. yarn add hardhat --dev
2. yarn hardhat

We use 1. to install hardhat, which is missing so far
and 2. is to retry your failed command :)
