Rails run an diferent application to current path

I have two Rails projects (project1: 3.2.11, project2: 4.2.4), whose folders are into the folder called Projects. In the terminal, when current path is /Users/me/Projects/project1 then, run rails s, when I visite localhost:3000, the project launched is the other one: /Users/me/Projects/project2, not the project I start from.
