##Fixing npm permissions

You may receive an EACCES error when you try to install a package globally. This indicates that you do not have permission to write to the directories that npm uses to store global packages and commands.

You can fix this problem using one of three options:

Change the permission to npm's default directory. Change npm's default directory to another directory. Install Node with a package manager that takes care of this for you. You should back-up your computer before moving forward.

1. Add gem 'will_paginate', '~> 3.0' to Gemfile
2. Add %w(will_paginate will_paginate/active_record).each {|lib| require lib} to config.ru
3. Assuming modular Sinatra, open Sinatra::Base and add include WillPaginate::Sinatra::Helpers so that all views can use will_paginate
4. In controller, @users = User.paginate(:page => params[:page], :per_page => 30)
5. In view, = will_paginate @users will generate the pagers

If you want to style your pagers

• Include this css in your layout
• Style it
