Ruby on Rails, error while generating project/installing extensions, json, how to fix?

Question

Ruby on Rails

Before writing here, I pretty much googled, but it did not bring any results.
Windows 7 x64
The problem occurs when generating a project, it cannot install plugins (not sure if I understand it correctly?).
Now I have

ruby -v
ruby 2.1.5p273 (2014-11-13 revision 48405) [x64-mingw32]

sqlite3 --version
3.8.8.1 

rails -v
DL is deprecated, please use Fiddle
Rails 4.2.0

And here at the stage of creating the project, the main problem arises, after the
rails new blog
command , the project is generated, it successfully goes to bundle install
, after which I get such an error.

run bundle install

Gem files will remain installed in C:/Ruby21-x64/lib/ruby/gems/2.1.0/gems/json1.8.2 for inspection.

An error occurred while installing json (1.8.2), and Bundler cannot continue.
Make sure that 'gem install json -v '1.8.2' ' succeeds before bundling.

When trying to manually install gem install json , the same error occurs.
Thanks for reading!

Answer 1

TL;DR: Your main mistake in using Windows. Well, Ruby is not intended for such perversions, put yourself at least on Ubuntu virtual machine and develop for your own pleasure. The `make` command is intended for compilation, as far as I remember, but in Windows it is stupidly absent. Teams.

Answer 2

In my office with rails, everyone works under Windows, everything was installed through railsinstaller.org/en - the flight is normal, there are only problems with mysql2, there you need to throw the dll somewhere
