I don't overtly sound like any well know bassist. However, When I'm playing a line I think about Nathan East or Marcus Miller or Terrance Palmer for example. How might they play this? I don't clone myself after them but their styles have greatly influenced how I think about bass and how I approach bass playing. But ,if the OP insists he has never been influenced by anything or anyone he has ever heard... ok.
I think people are being overly literal about the meaning of 'influence' and not thinking about what it means in a musical context, and why the question is asked.
If you look at somebody like Stevie Ray Vaughn, you can say (and he would have too) 100% that Jimi Hendrix is a big influence on his playing, because his licks have many of the hallmarks. The content of his playing references other players. This is what a lot of players take to be the contextual meaning of 'influence', when it is asked in relation to people. 'Who are your influences' is a different question to 'what are your influences'.
If you say that there aren't any people specifically that you would call an influence, this means that you don't consider there is any content in your playing you can significantly attribute to any other players. Players like this might think more abstractly about what they do.
If you take the view that everybody has to say 'everything' then the question itself is pointless and not worth asking. The question in an art context, is trying to find out what the artist thinks about their own work.
If you work with principles in your playing, then a lot of the time those principles aren't attributable to specific people. In this case, concepts and aesthetics may be more of an influence than the people themselves, and those central concepts don't necessarily have to have come from specific bass players. As such, 'nobody' is a fair answer. A bass player might use a book of knitting patterns as a conceptual basis for thinking about their playing, and may develop that by themselves for a long time, say years. At the end, would it be appropriate for them to have to name a person as their influence? John Coltrane studied harp music from books to develop his approach. How then is it appropriate for him to name a saxophonist as an influence on that branch of his playing?
I think there are many ways of viewing this question that are all valid, and I don't see why lots of people here insist there's only one way of looking at it.
