Seems like you called npm install from the wrong directory, the node modules got installed directly into your user directory.

You need to change into your Node-RED workspace directory first, usually ~/.node-red and call npm install from there.

Or probably better to use the install method built into node red. Select Manage Palette in the menu drop-down.
