'tiny-server' command not being recognized

I don't know if TinyServer is that well known, but it's used to open a localhost where you can locally host files on a certain folder. TinyServer is downloaded from Node(npm). To start TinyServer on a certain folder, you just cd to that folder in your cmd, and then type tiny-server. This always worked, but recently it started saying that tiny-server isn't a command. I've tried reinstalling TinyServer, and rebooting my pc, yet nothing works.
