I started getting this error...

Source file requires different compiler version (current compiler is 0.7.3+commit.9bfce1f6.Emscripten.clang) - note that nightly builds are considered to be strictly less than the released version

...a few days ago on the following line of code only:

pragma solidity ^0.8.17;

Anyway, this seems to be compiling without issues.

Anybody knows what may be causing this and how I can get rid of it?

  • What do you mean with environment? I am using Visual Studio Code with solidity extension.

  • Environment refers to the tools you are using to write the code. Like remix, hardhat, truffle, foundry. I assume you are using hardhat. This error might be coming from the hardhat config file because of different pragma versions in your smart contract and the config file.

  • Yes, I am using hardhat for compilation.

To get rid of these annoying warnings, the best way is to disable the solidity extension by Juan Blanco and enable the Solidity extension by Nomic Foundation.
