You first have to delete all instances of this node (and perhaps existing config nodes) and deploy  
Look in Menue/Manage Palette if there are still nodes **in use**.  
You can use CTRL/f to find nodes in your flows and the configuration nodes palette to find and delete unused config nodes.

As for why it fails deinstalling through the command, you're in the wrong directory. Emphasis added by me. You have to change to the Node-RED user directory first, which defaults to `/home/<username>/.node-red`.
