nodejs grunt can't be uninstalled

I don't know what I am doing wrong. :(

I tried running npm uninstall -g grunt and npm uninstall -g grunt-cli multiple times but no matter where I am, every time I call the command "grunt" in CMD I get the line "grunt-cli: The grunt command line interface. (v0.1.9)"

I tried installing grunt-cli using npm install -g grunt-cli but even though it said it installed version 0.1.13 whenever I called grunt it kept saying "grunt-cli: The grunt command line interface. (v0.1.9)"

I checked my system path but couldn't see anything related to grunt except for node itself.

edit: if I'll uninstall node and reinstall it will it fix this issue?

Thank you!
