Hi! Please let us know in wich lesson are you and what is the task you need to do. Thanks

[SantanuDK]

thanks sir it solved the problem i was using version 0.6.0. I thought since the solidity file is using 0.6.0 i should use it too

[PatrickAlphaC]

wait, so you used version 0.6.6 or 0.6.0?

[SantanuDK]

when i tried to compile using version 0.6.0 it thows me the error but after you told to use version 0.6.6 it worked just fine and no longer throws the error.

I had the same issue now. This solution helped me, thank you!

But why the hell do we specify version 0.6.6 in hardhat.config.js if we actually use version 0.6.0 in MockV3Aggregator.sol?

Maybe somebody can give me any hint, please?

[PatrickAlphaC]

We don't use 0.6.0, we use ^0.6.0. The MockV3Aggregator.sol should be ^0.6.6 for us.

Depending on your setup, 0.6.0 works, but we want the 0.6.6 stuff.

if anyone is still facing error add this in your hardhat-congif.js in module.exports
module.exports = {
paths: {
sources: "./mock",
},
