Would it be possible for a population of snakes to survive by eating nothing but fruit?

I was thinking of a scenario in which a population of snakes gets stranded on an island in which they are literally the only animals. This hypothetical island does not even have insects for the snakes to eat. The island does have dense forests of trees that produce fruit. All the fish and marine life in the water around the island is poisonous to the snakes so eating marine animals is NOT an option for the snakes. The snakes before getting stranded on this hypothetical island have only ever eaten small animals and have never eaten fruit before. Could the snakes on this hypothetical island survive entirely on the fruit that the trees produce? What effect would eating only fruit have on the evolution of the snakes on this hypothetical island? Would the snakes be able to rip fruit from trees on the island or would they have to eat fruit that fell from the trees.
