当我运行Rails Server时，它会复制我的所有文件

Question

When I run "rails s" in duplicates all my files. How do I run rails server? I created directory and decided to run rails server by running "rails s" but it just created the app files... which I already created with "rails new Raddit" Not sure what I did or what rails is doing since this is my first day at this

You did not set your rvm default,you need to run following commands.

source ~/.rvm/scripts/rvm .

rvm use 2.1.3 --default
