Really sorry to mess everyone around.
What I thought was a simple bugfix release seems to have broken something fundamental. Not least of which is that, somehow, a
.git folder now gets installed if you install uibuilder from the pallet.
No idea how that happens but, regardless, this was the final straw and I have reverted the 'latest' release back to v1.2.2.
You can install this manually from the command line by removing uibuilder and then reinstalling
cd ~/.node-red npm remove node-red-contrib-uibuilder npm install node-red-contrib-uibuilder
If you wish to do this from the palette manager in Node-RED, you may need to wait for a bit for the flows site to catch up so that it knows what the correct version is.
Again, sorry for messing people around. From now on, only priority bug-fixes will be applied to uibuilder v1 as I'm working as fast as possible to get v2 out.
