I have tried
pacman-key --init
but it too gave this error:
'pacman-key' is not recognized as an internal or external command, operable program or batch file.
I have also searched on chatGPT about how to install yaml.h in windows 11, it said:
For Windows, you typically don't need to install additional development headers separately as you might do on Unix-like systems.
