Node module update issue

My experience is this:

Find your global npm root folder

npm -g root

Then navigate to the node-red/node_modules folder below that.

Then

npm uninstall --unsafe-perm node-red-node-email

Restart node-red (you get a warning the module is missing), then install it via the palette manager. Also fully refresh the browser window (shift refresh).

You will find the same issue with the -rbe and the -twitter node.

YMMV
