Not able to Compile My Sol file

[AnugrahYadav]

Source file requires different compiler version (current compiler is 0.4.17+commit.bdeb9e52.Emscripten.clang - note that nightly builds are considered to be strictly less than the released versionsolc
Source file requires different compiler version (current compiler is 0.8.17+commit.8df45f5f.Emscripten.clang) - note that nightly builds are considered to be strictly less than the released version

This is the Error which I am constantly getting after getting through the Tutorial

Try pragma solidity ^0.8.7 or ^0.8.6, instead of 0.8.17

Hey , Thanks for replying first of all.
And I have tried that already and even tried to find the solution on the net but didn't find any recent solution most of them were as recent as 2021 ,I guess

@AnugrahYadav Which lesson are you following? And what is your pragma version for your smart contracts?

[AnugrahYadav]

Hey , Aly , Well I am following the same course and currently on 6:43:45 part of the video But due to course being 8 months old I am having trouble in having a proper extension along with the proper compiler I am trying to use pragma solidity ^0.8.7 but still getting the error in my code and I guess the compiler is 0.4.17 which is obviously outdated , If you know any way to just update the compiler version or get to know any way please tell me , And once again thanks for you humble help .

another thing that worked for me in this instance was pragma solidity >=0.6.0 <0.9.0; >

Hi @AnugrahYadav. Could you please share the code related to this issue? Sometimes, the contracts that your contract inherits from use different Solidity versions, and this tree can go up to requiring several versions at the same time.

That's why you might need to include these different compiler versions in your hardhat.config.js file, in such a way:

solidity: {
  compilers: [
    {
      version: '0.8.8',
    },
    {
      version: '0.4.24',
    },
  ],
},
