Lesson 7 : Unexpected error when running npx hardhat deploy

[LeNooooooo]

Hello,

On the lesson 7, at the beginning of the hardhat setup, on the part about deploying, I've followed all the instruction specifically about running this command :

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

it seems to modify correctly the package.json:

{
  "devDependencies": {
    "@chainlink/contracts": "^0.4.2",
    "@nomicfoundation/hardhat-toolbox": "^1.0.1",
    "@nomiclabs/hardhat-ethers": "npm:hardhat-deploy-ethers@^0.3.0-beta.13",
    "@nomiclabs/hardhat-etherscan": "^3.0.0",
    "@nomiclabs/hardhat-waffle": "^2.0.0",
    "chai": "^4.2.0",
    "dotenv": "^10.0.0",
    "eslint": "^7.29.0",
    "eslint-config-prettier": "^8.3.0",
    "eslint-config-standard": "^16.0.3",
    "eslint-plugin-import": "^2.23.4",
    "eslint-plugin-node": "^11.1.0",
    "eslint-plugin-prettier": "^3.4.0",
    "eslint-plugin-promise": "^5.1.0",
    "ethereum-waffle": "^3.0.0",
    "ethers": "^5.6.9",
    "hardhat": "^2.10.1",
    "hardhat-contract-sizer": "^2.6.1",
    "hardhat-deploy": "^0.11.12",
    "hardhat-gas-reporter": "^1.0.4",
    "prettier": "^2.3.2",
    "prettier-plugin-solidity": "^1.0.0-beta.13",
    "solhint": "^3.3.7",
    "solidity-coverage": "^0.7.16"
  }
}

So after i've created, in the deploy folder as explain by Patrick, a file named 01-deploy-fund-me.js with this content :

 function deployFunc() {
   console.log("Yo");
}
 module.exports.defaut = deployFunc;

But when I run npx hardhat deploy, i've got this error :

You have both ethereum-waffle and @nomicfoundation/hardhat-chai-matchers installed. They don't work correctly together, so please make sure you only use one.

We recommend you migrate to @nomicfoundation/hardhat-chai-matchers. Learn how to do it here: https://hardhat.org/migrate-from-waffle

I really don't know what to do, as I follow the tutorial, try to find answer on differents place, but I can not find the problem.

Is anybody can please help me, I'm totally stuck here

Thanks

• yarn remove @nomiclabs/hardhat-waffle ethereum-waffle
• yarn add --dev @nomicfoundation/hardhat-chai-matchers
• In your Hardhat config, import the Hardhat Chai Matchers plugin and remove the hardhat-waffle one:

- import "@nomiclabs/hardhat-waffle";
+ import "@nomicfoundation/hardhat-chai-matchers";

• If you were not importing the @nomiclabs/hardhat-ethers plugin explicitly (because the Hardhat Waffle plugin already imported it), then add it to your config:

import "@nomiclabs/hardhat-ethers";

Hope this helps

Thanks for these inputs, I've made the modification, but the mistake (and I am sorry to put a question here for this), was that I forgot the "l" to default in the deploy file.....shame on me :)

[krakxn]

Nah, it is just that packages you were importing is deprecated. Just follow the above and it should fix the problem.

[LeNooooooo]

yes i've done it, + add the missing "l", and it s working now, thanks again

[krakxn]

Awesome. All the best!

@LeNooooooo See the 01-deploy-fund-me there is an issue. If you will not be able to find yourself then push the code to GitHub and leave a link here.

[LeNooooooo]

I've seen it, "l" on default.....sorry to have disturb you guy for this....

[alymurtazamemon]

@LeNooooooo No issue.
