It sounds as if you have somehow not got write permission to some files, possibly you installed a node using sudo (which you should not do unless you are installing with -g). To restore permissions to all files in your home folder you can run

```auto
sudo chown -R pi:pi /home/pi

```

Or if you just wanted to do that on the .node-red folder then  
`sudo chown -R pi:pi /home/pi/.node-red`

As always when using sudo take care when entering it as typos can be disastrous when using sudo. Preferably you should look up the commands being run and make sure they are ok.
