How to solve " 'stdio.h' file not found" message in editor?

[DustyOldRowe]

Summary

I decided to try out Helix recently as my code editor for C, I installed, clangd and LLVM, all the things you need, but when I write "<stdio.h>" I'm shown a message in the editor that says " 'stdio.h' file not found", I searched for solutions, generated the compile_commands.json file and still didn't solve my issue and I don't know what to do anymore.

does your program compile or does it show a similar error when you try to do it?

[DustyOldRowe]

It compiles and runs normally when I run the gcc command in the terminal.

then it's most likely a problem with your C standard libraries. I'm not sure how it works in windows, so maybe someone else might be able to help you fix them, but try adding them to your path, since it looks like they're not there.
