fortunately, you don't have to switch to ruby 2.0
there is a solution to this issue, after endless trying...

https://github.com/hwding/sqlite3-ruby-win

Steps

Pre

• gem uninstall sqlite3 --all

Source

• Download the latest sqlite3-ruby, https://github.com/sparklemotion/sqlite3-ruby
• unzip the package

Build

• run command-line in the extracted dir
• make sure you have your C compiler installed and added to PATH
• gem install bundler
• bundle install
• rake native gem
• you'll find a dir named 'pkg' generated

Install

• enter dir 'pkg'
• gem install --local sqlite3-xxx.gem ('xxx' is version code)

Check

• irb
• require 'sqlite3'

The issue is that binary sqlite3 gem do not include pre-compiled versions for Ruby 2.1.3

This is mentioned in the sqlite3-ruby mailing list here.

In the folder of your project open terminal and execute:

bundle update sqlite3

bundle update nokogiri

I hope i have helped you ;)

EDIT:

• i always recommend using linux/mac for ruby, because some gems may get problematic, because of compiling errors with c

• always use bundle to manage your gems, it is much easier*, you can install it by:

  • gem install bundler

  • bundle install - will install all the gems in your Gemfile

  • the last bundler version is not compatible withe ruby bellow 2.3, so use gem install bundler -v 1.16.4
