 # ./app/views/users/index.html.erb:5:in `each'
 # ./app/views/users/index.html.erb:5:in `_app_views_users_index_html_erb__3004047397113020476_70255017945740'

Answer 1

Chapter 7’s first exercise specifies that you extend the gravatar_for method to include a new, optional parameter for including size. You likely didn’t do this exercise and so it is only expecting the original 1 argument as opposed to both arguments. Complete the exercise and you should get this code to pass.
