Welcome to the forum @martin8094. The significant part is at the bottom where it says
node-red-admin@0.1.5
added 56 packages from 73 contributors in 24.352s
That means that it succeeded. The stuff above is all about various things it tried on the way to installing it and so can be ignored. Provided at the end you see the message saying it was installed then all is well. If it failed the last thing shown would be an error.
