I've installed Ruby and in the User Variables, I can see that Path = C:\Ruby22-x64\bin
However, when I run ruby in the cmd, it says 'ruby' is not recognized as an internal or external command, operable program or batch file.
I've accidentally deleted the Path in System Variables and I think that's why it's not working.
Could anyone guide me on how to restore or add the Path in the System Variable?
Thank you in advance!
