Mock3Aggregator.sol refuses to compile

Question

I am currently working on deploying a contract in my local hardhat network, the files below:

1. MockV3Aggregator.sol - the smart contract

    pragma solidity ^0.6.0;
    
    import "@chainink/contracts/src/v0.6/tests/MockAggregator.sol"

2. The 00-deploy-mocks.js --- the file responsible for deploying the smart contract

  const {
      developmentChain,
      DECIMALS,
      INITIAL_ANSWER,
  } = require("../helper-hardhat.config")
  
  module.exports = async ({ getNamedAccounts, deployments }) => {
      const { deploy, log } = deployments
      const { deployer } = await getNamedAccounts()
  
      if (developmentChain.includes(network.name)) {
          log("Local Network detected! Deploying mocks... ")
          await deploy("MockV3Aggregator ", {
              contract: "MockV3Aggregator",
              from: deployer,
              log: true,
              args: [DECIMALS, INITIAL_ANSWER],
          })
          log("Mocks Deployed...")
          log("_________________________________________")
      }
  }

and my hardhat-config.js

 require("hardhat-deploy")
 
 /** @type import('hardhat/config').HardhatUserConfig */
 module.exports = {
     // solidity: "0.8.8",
     solidity: {
         compilers: [{ version: "0.8.8" }, { version: "0.6.0" }],
     },
     networks: {
         sepolia: {
             url: process.env.SEPOLIA_RPC_URL || "",
             accounts: [],
         },
     },
     gasReporter: {
         enabled: process.env.REPORT_GAS != undefined,
         currency: "USD",
     },
     etherscan: {
         apiKey: process.env.ETHERSCAN_API_KEY,
     },
     namedAccounts: {
         deployer: {
             default: 0,
         },
     },
 }

It keep giving this error in my terminal when i run the code below in my terminal:

Nothing to compile
Local Network detected! Deploying mocks...

Answer 1

I belive this should fix your error...

use:

import "@chainlink/contracts/src/v0.6/tests/MockV3Aggregator.sol";

Answer 2

In the contracts\test\MockV3Aggregator.sol Make sure to have import "@chainlink/contracts/src/v0.8/tests/MockV3Aggregator.sol";
