Strange error in terminal after importing hardhat-gas-reporter in HardHat SimpleStorage

[trevorwrightdev]

I am doing the HardHat simple storage project right now, and I have just installed the hardhat-gas-reporter plugin. When trying to install it, I got this error:

Error HH801: Plugin @nomicfoundation/hardhat-toolbox requires the following dependencies to be installed: @ethersproject/providers, @nomicfoundation/hardhat-network-helpers, @nomicfoundation/hardhat-chai-matchers, @nomiclabs/hardhat-ethers, @types/chai, @types/mocha, @typechain/ethers-v5, @typechain/hardhat, chai, solidity-coverage, ts-node, typechain, typescript. Please run: npm install --save-dev "@ethersproject/providers@^5.4.7" "@nomicfoundation/hardhat-network-helpers@^1.0.0" "@nomicfoundation/hardhat-chai-matchers@^1.0.0" "@nomiclabs/hardhat-ethers@^2.0.0" "@types/chai@^4.2.0" "@types/mocha@^9.1.0" "@typechain/ethers-v5@^10.1.0" "@typechain/hardhat@^6.1.2" "chai@^4.2.0" "solidity-coverage@^0.8.1" "ts-node@>=8.0.0" "typechain@^8.1.0" "typescript@>=4.5.0"

This was weird, but I just did what the message recommended and I installed the listed packages using yarn. So this error is NOT the direct problem at the moment. However, when I tried to run yarn hardhat test I get a new error.

` SimpleStorage

1) "before each" hook for "Should start with a favorite number of 0"

I am not really sure how to solve this. It just happened when I installed hardhat-gas-reporter package. Can someone help me out?

first problem:
please yarn add the dependencies, copy from down below and paste in the terminal and run:
yarn add @ethersproject/providers, @nomicfoundation/hardhat-network-helpers, @nomicfoundation/hardhat-chai-matchers, @nomiclabs/hardhat-ethers, @types/chai, @types/mocha, @typechain/ethers-v5, @typechain/hardhat, chai, solidity-coverage, ts-node, typechain, typescript. Please run: npm install --save-dev "@ethersproject/providers@^5.4.7" "@nomicfoundation/hardhat-network-helpers@^1.0.0" "@nomicfoundation/hardhat-chai-matchers@^1.0.0" "@nomiclabs/hardhat-ethers@^2.0.0" "@types/chai@^4.2.0" "@types/mocha@^9.1.0" "@typechain/ethers-v5@^10.1.0" "@typechain/hardhat@^6.1.2" "chai@^4.2.0" "solidity-coverage@^0.8.1" "ts-node@>=8.0.0" "typechain@^8.1.0" "typescript@>=4.5.0"

second problem:
please paste your code here.

Ok, I did actually install the dependencies previously, I just mentioned this error just in case it had something to do with the second error. Here is my hardhat config code:

require('dotenv').config()
require("@nomicfoundation/hardhat-toolbox");
require('@nomiclabs/hardhat-etherscan')
require('./tasks/block-number')
require('hardhat-gas-reporter')

const GOERLI_RPC_URL = process.env.GOERLI_RPC_URL
const PRIVATE_KEY = process.env.PRIVATE_KEY
const ETHERSCAN_API_KEY= process.env.ETHERSCAN_API_KEY

/** @type import('hardhat/config').HardhatUserConfig */
module.exports = {
  defaultNetwork: "hardhat",
  networks: {
    goerli: {
      url: GOERLI_RPC_URL,
      accounts: [PRIVATE_KEY],
      chainId: 5,
    },
    localhost: {
      url: 'http://127.0.0.1:8545/',
      chainId: 31337,
    }
  },
  solidity: "0.8.7",
  etherscan: {
    apiKey: ETHERSCAN_API_KEY,
  },
  gasReporter: {
    enabled: true
  }
};

Here is my test code:

const { ethers } = require('hardhat')
const { expect, assert } = require('chai')

describe('SimpleStorage', function () {
  let simpleStorageFactory, simpleStorage
  beforeEach(async function () {
    simpleStorageFactory = await ethers.getContractFactory('SimpleStorage')
    simpleStorage = await simpleStorageFactory.deploy()
  })

  it('Should start with a favorite number of 0', async function () {
    const currentValue = await simpleStorage.retrieve()
    const expectedValue = '0'
    assert.equal(currentValue.toString(), expectedValue)
  })
  it('Should update when we call store', async function () {
    const expectedValue = '7'
    const transactionResponse = await simpleStorage.store(expectedValue)
    await transactionResponse.wait(1)
    
    const currentValue = await simpleStorage.retrieve()
    assert.equal(currentValue.toString(), expectedValue)
  })
})

Thank you!

Hi, I run your code and it looks fine on my end.
if you still face errors, can you please upload your whole code to github and leaves a link, I will look into it.

It should be fixed after the following:

• Copy and use the package.json from the course's repo
• Delete node_modules manually
• yarn hardhat clean
• yarn install
• Import all the necessary packages in your hardhat.config (can copy from the course's repo)
• yarn hardhat compile
