I would remove the sqlite node and reinstall.? You might need to remove the sqlite node manually via the command prompt.? I think all the nodes in Node Red are installed though the npm manager.
I would try issuing sudo npm uninstall node-red-node-sqlite and let it do it's thing, reboot and try installing again letting the install finish with the GUI before moving on.? It will take a while.? Maybe 15 mins or so.
