Question

I installed Sinatra using RubyGems, created a simple file called hello.rb

file contains:

 require 'rubygems'
require 'sinatra'

get '/' do
  puts "Hello World"

end

I navigated on the terminal to desktop on mac to where i saved the hello.rb and did run the file by: ruby hello.rb it gives me message it is running with WEBrick on this port 4567
I went to localhost:4567 then i get this message “Sinatra doesn’t know this ditty.”

Do i have to save the hello.rb file to the WEBrick server folder to make it work? if so, where is that folder located on the mac?

Answer 1

You have to return something, as in:

get '/' do
  "Hello World" # the return is implicit
end

Then it will work. puts prints to the command line but returns nil, so nothing was being returned to sinatra.
