ParserError: Source file requires different compiler version (current compiler is 0.8.7+commit.e28d00a7.Emscripten.clang) - note that nightly builds are considered to be strictly less than the released version --> @chainlink/contracts/src/v0.6/vendor/SafeMathChainlink.sol:2:1: | 2 | pragma solidity ^0.6.0; | ^^^^^^^^^^^^^^^^^^^^^^^

On the fundMe lesson, when I try to import the safemath, that's the error I am getting
I have tried to copy the same
even with the interface it can only work if I past in the source code otherwise it bounces the error

Try using the 0.8.7 version.

pragma solidity ^0.8.7; // change 0.6.0 to 0.8.7

To my understanding, and stated in the video, starting with Solidity 0.8.0 safemath is unneeded because it's built into Solidity. In that case, you will not need to import that module.

True I heard that too, but it's like even the first interface which is not safe math don't work as well by importing unless one pastes the whole code in there. In other words importing any external interface don't work But if you copy the code and make an external file that's not a link It also works That's the angel of possibility I am trying to understand

@Stmbisa paste in (or add pictures of) your .sol code and your brownie-config.yaml code. My initial thoughts are maybe your non-SafeMath import is the wrong version or your dependencies/remappings in the config file have a typo. Also, it would be helpful to see what the error is once you've removed the SafeMath import since that's not needed for Soldity v0.8.0+

See the problem only comes when i use IMPORT with remix, but if I copy and paste no error happens, I mean even when I copy Patrick's code and past it in remix with those imports it brings same errors, but if I switch by pasting the source code instead of importing, the error is gone. I think its a problem with remix, its good I won't be using remix all along, moved on the good thing I understood the concept.
I appreciate your help @itgav and @fiatbruno
