Lesson14: Compiler Version Problem!

[ZahraaHawie]

Hello.. I have a problem in my compiler version.. MockV3Aggregator.sol needs a compiler of 0.6.0 version and it's always getting error although I updated solidity compilers in hardhat.config.js but it is not working with double compilers..

hardhat.config.js

  solidity: {
    compilers: [
      {
        version: "0.6.0",
      },
      {
        version: "0.8.0",
      },
    

MockV3Aggregator.sol

// SPDX-License-Identifier: MIT
pragma solidity ^0.6.0;

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

Other contracts are working normally pragma solidity

Any help of why I cant work with double compilers?

It worked when I updated MockV3Aggregator to pragma solidity >=0.6.0 <0.9.0;
