when i use :pragma solidity 0.8.20; i get
Source file requires different compiler version (current compiler is 0.8.19+commit.7dd6d404.Emscripten.clang) - note that nightly builds are considered to be strictly less than the released version

when i change to: pragma solidity >=0.8.19 <0.9.0;

i get an error with my: import {Test} from "forge-std/Test.sol";
Source "forge-std/Test.sol" not found: File import callback not supported

please help

@monaldmuck Here is the documentation of the solc-select package which allows switching between solidity versions. Install the required version using it and see.

Hello @monaldmuck , did you figure it out already with the help of @alymurtazamemon ?

naw getting this now
Warning (3420): Source file does not specify required compiler version! Consider adding "pragma solidity ^0.8.20;"
--> test/invariant-break/handler/Invariant.t.sol

@monaldmuck The file is not compatible with your required solidity version. Check foundry.toml file which version you have specified there and make sure every file is compatible according to it.

[compiler]
solidity_version = 0.8.20 i am updating the foundry.toml file
and when running fuzz test getting:
Error:
failed to extract foundry config:
foundry.toml error: TOML parse error at line 32, column 23

@monaldmuck it is solc

solc = "0.8.20"

I appreciate all the support
