Lesson 7 npx hardhat deploy --tags mocks returns Nothing to compile

[engrusmanbelloa]

Hi everyone, i am trying to deploy mocks with mock tag but it returns nothing to compile, if i delete the cache and artifacts folders everything compile successfully but no mock deployment logs such as local network detected etc. below is the code i am working on thanks your helping hands.

00-deploy-mocks.js

const {
    network
} = require("hardhat")

const {
    deploymentChains,
    DECIMALS,
    INITIAL_ANSWER
} = require("../helper-hardhat-config")

module.exports = async ({
    getNamedAccounts,
    deployments
}) => {
    const { // deploy and log from deployments
        deploy,
        log
    } = deployments
    const { // get the deployer from getNamedAccounts / accounts
        deployer
    } = await getNamedAccounts()

    if (deploymentChains.includes(network.name)) {
        log("Local network detected! deploying mocks...")
        await deploy("MockV3Aggregator", {
            contract: "MockV3Aggrigator",
            from: deployer,
            log: true,
            args: [DECIMALS, INITIAL_ANSWER]
        })
        log("Mocks deployed successfully!")
        log("__________________________________")
    }
}

module.exports.tags = ["all", "mocks"]

helper-hardhat-config.js

const networkConfig = {
    4: {
        name: "rinkeby",
        ethUsdPriceFeed: "0x8A753747A1Fa494EC906cE90E9f37563A8AF630e"
    },
    137: {
        name: "polygon",
        ethUsdPriceFeed: "0xF9680D99D6C9589e2a93a78A04A279e509205945",
    },
}

const developmentChains = ["hardhat", "localhost"]
const DECIMALS = 8
const INITIAL_ANSWER = 200000000000

export default {
    networkConfig,
    developmentChains,
    DECIMALS,
    INITIAL_ANSWER
}

There are three problems in your code

1. you define {developmentChains} in helper-hardhat-config.js

export default {
    networkConfig,
    developmentChains,
    DECIMALS,
    INITIAL_ANSWER
}

but you use it as { deploymentChains } in your 00-deploy-mocks.js

const {
    deploymentChains,
    DECIMALS,
    INITIAL_ANSWER
} = require("../helper-hardhat-config")

and there

 if (deploymentChains.includes(network.name)) {}

2. it is MockV3Aggregator not MockV3Aggrigator, check your code again

await deploy("MockV3Aggregator", {
            contract: "MockV3Aggregator",
            from: deployer,
            log: true,
            args: [DECIMALS, INITIAL_ANSWER],
        }

3. it's "module.exports" not "export default"

module.exports = {
    networkConfig,
    deploymentChains,
    DECIMALS,
    INITIAL_ANSWER,
}

check your code again

export default {
    networkConfig,
    developmentChains,
    DECIMALS,
    INITIAL_ANSWER
}

hope this can help you! good luck.

@engrusmanbelloa Informative answer! Please checkout How to answer questions guide for better formatting answers. Thanks.

[engrusmanbelloa]

i dont what happened actually i have deleted everything copied from the repo but i still dont get response and no errors. thanks for your time.

[engrusmanbelloa]

another thing i realized is that the solidity coverage plugin has issue because if i run yarn hardhat coverage i get the following error

Error in plugin solidity-coverage: ReferenceError: window is not defined

maybe it might be the reason i am not seeing any response if i run hardhat deploy with mock tags and i checked its require syntax i get the issue as well.

Could not find a declaration file for module 'solidity-coverage'. '/home/nait/IT/chain/HH-FundMe/node_modules/solidity-coverage/plugins/nomiclabs.plugin.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/solidity-coverage` if it exists or add a new declaration (.d.ts) file containing `declare module 'solidity-coverage';`ts(7016)

thanks a lot for your heping hand sir.

And if i run yarn hardhat test i get following error as well.

1. Did you modify your code as I said? If you do, the code is definitely fine. Because your code runs fine on my VSCode.
2. Did you install all the plugins mentioned in the video? Please check it again.

[engrusmanbelloa]

yes i did modify the code sir, i install all the plugins said in the video. i think i have another problem with coverage plugin as well, it does install correctly but when required it says "Could not find a declaration file for module 'solidity-coverage'." is it possible that the problem could be from my editor?

Hi, did you guys fixed that? I am having the same issue. when I do yarn hardhat deploy --tags mocks it compiles the contracts but it seems like doesn't run the "00-deploy-mocks.js" script like it does on the 10:49:30 minute.

It would be amazing if someone could help us with that.
Thx

[engrusmanbelloa]

Hello sorry for the late reply please, in my case i used npm package from the beginning of the lesson, when i changed to yarn and started afresh everything worked fine. it means some of the packages were not installed correctly using npm.

That is the same issues am having even with yarn in my own case

Hi guys if you are still having this issue with the tags in your deploy scripts try this:

yarn hardhat deploy --tags "mocks"

Make sure you put the " " around the tags in the command line

Cheers,

Ben
