You also need to restart Node-RED for it to load the changes

what were the exact commands you used to stop/start node red?  
how did you install node-red?

when in doubt, you could reboot the machine node-red is running on.

An installed module should be in `~/.node-red/node_modules` ?

Try `node-red-stop; node-red-start` next time
