I just had this same issue. I ran 'spring stop' then 'rails c' and it corrected the error. Something got mucked up with the environment because line 41 of that irbrc.rb file refers to the ENV variable GEM_HOME, which I confirmed was actually set.
Does that fix your issue?

EDIT: this is happening when I run rails console too.
I am new to the ruby environment. I configured ruby and when I start the server I am hit with the series of errors. Can someone please give me a hand please.

You are trying to start rails server in interactive Ruby Shell (IRB or irb), or may be rails console.
use the command
rails s
in your terminal
You should have to look into this http://guides.rubyonrails.org/getting_started.html for the rails basics.
You are using rails console. Get out of the console by typing quit and then type rails s
I am trying to create a new rails app on Ubuntu 14.04. This is my first time using Rails in Ubuntu, (previously developed in Windows 10). I set up the development environment, my ruby version is ruby 2.3.0p0 and rails version is 5.0.0. Once my dev environment was set up, I started a new project by typing in a terminal:
rails new MyApp
Then, I typed:
cd MyApp
bundle install
And finally, I attempted to start my rails server by typing:
rails s
Instead of the rails server starting, I get this response in the terminal:

My app was created successfully. All the appropriate files are located in my app's folder. I just can't seem to get the rails server to start.
I found a solution. Open a terminal and change to your app's directory. Example, type cd MyApp.
Then install the Rubyracer gem by typing gem install therubyracer in your terminal, and then add gem 'therubyracer' to your gemfile.
My rails server starts now. Thank you uDaY for helping me.
