While I am trying to create the new rails project, I face to error that is related to the lack of json gem.
When I try to install json gem, this error happens:

If you want to install Ruby 2 (or greater) on Windows 7 (64 bit), you need to install DevKit 64 bit as well. Your Devkit has to be compatible with your operating system.
So, make sure you installed the correct Ruby and the compatible Devkit on your system.
See this tutorial for more information.
There was a group of gems which are dependent together. So, I had to install step by step.
As I did it based on error messages and one by one, I forgot to make a note about the steps.

Please help me to get rid of this error.

If I succeed then I would tell ya!

It could be my Ruby versions (I have both 2.2 and 1.9), but I do not know. What is going on?
After #Azolo posted his comment, I discovered that the DevKit version I was using did not match the Ruby version I was running. The problem came to be because I needed Ruby 1.9.3 on the path for the Heroku client to function, but was trying to use 2.2 DevKit (as I typically use Ruby 2.2 for development.
I am trying to set up rails in my mac(Yosemite) machine. But when I do

What am I missing here.??
I think rvm might be trying to use gcc 4.6, which doesn't work properly with rvm. I believe you can:
Uninstall gcc 4.6 (brew rm gcc46)
Pull the latest rvm (rvm get stable)
Retry gem install rails

I have Win7 x64, Ruby 2.0.0, DevKit (DevKit-mingw64-32-4.7.2-20130224-1151)
I faced the same issue. My solution:
Download gem source from github - https://github.com/cloudfoundry/caldecott/archive/master.zip
Unzip to C:\caldecott (for example)
Open file caldecott.gemspec and change version of json dependency to "~> 1.7"
Open command prompt, move to gem source directory and perfrom:
gem build caldecott.gemspec
gem install caldecott-0.0.5.gem
That's all
This error occurs with Ruby 2.0.0 version. Downgrade to Ruby 1.9.3
