NPM modules referenced from the settings.js in the functionGlobalContext need to be installed in the userDir because they are loaded relative to the active settings.js file.

Both the userDIR and settings.js file that are in use are logged in the first few lines of output when Node-RED starts up.

You should only be editing the settings.js file in the userDir. The version in the Node-RED install dir is only used when setting up new userDir's. You will also need to restart Node-RED when ever you edit this file.
