look around your home/area and look for zombie villagers if you don't have any , find 2 and heal them , make your own village and let them breed
if they are not farmers you need to feed them manually , throw them food.
here is a village i built
this works in 1.12 also
and here is how to heal a zombie villager
the cure process is pretty much the same except the gold apple you need to craft it out 9 ingots
