How do you relaunch and preview a rails app e.g. 'myproject' from terminal after closing it?

I'm working with rails on OSX, and after having built a basic website app called 'myproject', I can't seem to open the app again in Terminal so that I can get a link to "localhost:3000" again and preview my site.

When I open terminal and navigate to myproject "cd myproject" and then say "rails s", the terminal spits out a bunch of Usage guidelines.

What am I doing wrong? I just want to be able to launch my app project 'myproject' again so I can continue working on it.

What are the usage guidelines it's giving you?

Actually it's giving me this:

It seems like it's trying to tell me to do something in particular.

Oof, that is hard to read! :P

It's telling you there's an unexpected end-of-input in application.rb:11 which means there's a typo/mistake around line 11 of application.rb. I'm new to this also so I may not be that helpful, especially without seeing that application.rb file.

Yeah you're probably just looking for a missing or extra 'end' somewhere. Hope this helps!

Ok, I think that's helpful. I'll check out the syntax in that file and see if that works.

Thanks Tyler, that worked -- I had just added a bad bit of code on line 11 that needed to be taken out.
