Rails Server keeps exiting on “rails server” command

Question

Here are my specs: Ruby 2.4.0, Rails 5.1.3, postgres 9.6, windows 10 running rails with Bash Ubuntu. Whenever I try running rails server it exits me, I'm at the root of the project. It wasn't happening before. Here are the gems I recently installed: boostrap-sass, devise, toastr-rails, omniauth, omniauth-facebook

 rails server
 => Booting Puma
 => Rails 5.1.3 application starting in development on http://localhost:3000
 => Run `rails server -h` for more startup options
 Exiting

删除文件夹或文件/mnt/c/Users/xxxxx/Desktop/xxxxx/tmp/pids然后重试？
