Judging by your error, you're trying to use Rails v2.3.5 with ruby 2.0.0. Without doing a lot of googling I can't be certain, but I'm fairly sure that old versions of Rails like that only work with ruby 1.8.7.
Unless you have a really good reason to use a version of Rails that old, you shouldn't do it.
Use a new Rails, or if you have to use that Rails then install ruby 1.8.7

What does undefined method `configure' for nil:NilClass (NoMethodError) mean?
I tried reinstalling and reinstalling. I'm also have trouble updating the GEMFILE to ruby 2.4.2. Your Ruby version is 2.4.2, but your Gemfile specified 2.2.5. I tried "bundle update" removing 2.2.5 but it gives me a error... I tried everything. and now I get this nil:Nil:Class error... PLease help!
The last known error I did was to remove the .ds-store and i typed something add gitignore or something because I was having trouble with the git pull. I found this while I was troubleshooting and I also hit git commit - m " ".
This was when the nil:Nil:Class error popped up each type i try to run the rails s.

What Ruby version manager are you using, i would suggest you to use rvm to maintain ruby manager and with rvm use ruby~2.2.5 as it is mentioned in your gem file. first go to project directory and change your ruby version to 2.2.5 and then run bundle update. this may resolve your issue. RVM

Upon research in SOF, found from the link and other link that the nokogiri needs to be updated in the Gemfile. I updated and executed the Bundle Install command. Even after that, its not working. Please suggest me the ways to fix it. FYI, I am using the latest versions of gems.
I also updated my Gemfile with
gem 'rack', '~> 1.6.0'
It did not work.
Install an older version of rails (4.0.0) because I think windows doesn't have stable version of rails > 4.0.
Change the version in gemfile.

I get the exact same error when trying rails new mynewapp, except instead of
...gems/rails-api-0.4.0/bin/rails-api:3:in `<top (required)>'
I get
...gems/railties-4.2.4/bin/rails:9:in `<top (required)>'
And even running rails -v gives the same error.
Google was no help. Does anyone have any idea what might causing this?
If you run rails -v and get an error, your installation is probably bad. I'd try re-installing rails...
Follow this:
http://installrails.com/
It looks like thor 0.19.1.1 made a breaking change. Try changing it to 0.19.1 and see if that fixes the issue.
I'm getting this error message when I try the "rails server" command... not really sure what's going on?

Have you tried reinstalling the 'sqlite3-ruby' gem?
There might be some sqlite-ruby interface issue in your system as this SO answer, Sqlite3 error after Rails 3 (beta 4) install, points out.
And also, you should use rvm/rbevn and ruby 1.9 if there isn't any specific requirement for ruby 1.8.
I am completely new to ror and am following Michael Hartl's tutorial but I keep getting an error when I get to section 1.2.5. using the rails server command. When I use this command (whilst I am in my rail app directory 'first_app') I get the following error

I can't figure out what went wrong, my bundle installed fine (section 1.2.4).
If your Gemfile is not set to use rails 3.1 or greater, try updating to 3.1.
