Is bass guitar difficult to learn?

I’m currently trying to get a band together with a few friends, and they’re in need of a bassist. We’ve decided it would be best for me to try and learn bass guitar to ensure that we don’t have to go look for another band member.

Now, as far as instrument experience goes, I only know how to play piano. Would it be difficult for me to try and pick it up with no prior guitar knowledge? Let me stress, I have next-to-no guitar knowledge
