expo-cli successfully installed but doesn't work

I have successfully installed expo-cli by using yarn global add expo-cli but I can’t see it in any folder nor in node npm modules neither in AppData\Roaming. When I run expo diagnostics command it says ‘expo’ is not recognized as an internal or external command,
operable program or batch file. Screenshot is attached:

Hi.

echo $PATH is a Unix/Linux/Mac command. It will not work on Windows unless you’re running it inside “WSL”.

It seems that the bin directory that yarn installed the expo command to is not in your PATH, so you’re on the right track.

Try running yarn bin and that will hopefully tell you where it is. Then add that directory to the PATH.
