My child only wants to play with one kid. how do I get her to make other friends?

Well, the first step would be to understand what’s going on. Does your child feel that she is being treated unfairly or bullied?  Or is she being a bully?  Does she have other friends at home?  Are you happy with her social skills?  Is there anything different going on at school?  Does the other child have a strong personality?

My child is treated fine but just not interested in playing with other friends besides the one.

Is there something in the relationship that she likes?  Or, are there unmet needs that she’s hoping the friend will address?

Well then, what if I shared with your child an “Aesop’s Fable”, that you might use as a good role model for a strong, moral adult to follow:  
“The Ant and the Grasshopper”

The ant works hard in the withering heat all summer long, building his house and laying up supplies for the winter.  The grasshopper thinks the ant is a fool and laughs and dances and plays the summer away.  Come winter, the ant is warm and well fed.
