rails s not working with my app - ruby-on-rails

Question

Hey guys I have been working on a rails app, and the rails server was working. Then I added more code, and all the sudden the rails server is not working now. I keep getting this message:

Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.
Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.
Example:
rails new ~/Code/Ruby/weblog
My app is called bloccit, and in my terminal shell I am in my code/bloccit directory but still nothing. If anyone could help with any tips I would be very thankful!

Answer 1

rails s runs scripts located in your app's bin directory. Without it, you get the message shown above.
I asked for the contents of your app directory (using ls) and you responded:
Gemfile Rakefile config.ru log tmp Gemfile.lock
app db public vendor README.md config lib spec
As you can see, your bin directory is missing. It must be restored/replaced.
If you moved it or threw it in the trash, restore it.
If you deleted it, you can copy one from another/new Rails app. Create a folder somewhere outside your existing app, generate an empty Rails app (rails new throwaway), then go in and copy the bin folder to your existing app.

Answer 2

Make sure that you are in your root application directory. That error you posted is commonly seen if you are not in root application directory.
You can use pwd command to show where is your current directory. You said that your app name is bloccit and you should be in that root directory and fire rails s.

Answer 3

It's likely that it's suggesting you to create a new rails app because it's unable to identify your Rails app.
Since you're using Rails version 4.x, it looks for bin/rails to identify a Rails app. If you don't have bin directory at the root of your application, try to run rake rails:update:bin
