I'm newbie to Ruby on Rails . When I try to setup basic installation and initiation of server using rails 4.0.0 on ruby 2.0.0 ., I'm facing above error message.
How can I avoid this error message and proceed further ?
Full Error Message:
/usr/local/lib/ruby/gems/2.0.0/gems/sqlite3-1.3.7/lib/sqlite3.rb:6:in `require': cannot load such file -- sqlite3/sqlite3_native (LoadError) from /usr/local/lib/ruby/gems/2.0.0/gems/sqlite3-1.3.7/lib/sqlite3.rb:6:in `rescue in ' from /usr/local/lib/ruby/gems/2.0.0/gems/sqlite3-1.3.7/lib/sqlite3.rb:2:in `' from /usr/local/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:72:in `require' from /usr/local/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:72:in `block (2 levels) in require' from /usr/local/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:70:in `each' from /usr/local/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:70:in `block in require' from /usr/local/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:59:in `each' from /usr/local/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:59:in `require' from /usr/local/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler.rb:132:in `require' from /home/penchal/new/site/config/application.rb:7:in `' from /usr/local/lib/ruby/gems/2.0.0/gems/railties-4.0.0/lib/rails/commands.rb:76:in `require' from /usr/local/lib/ruby/gems/2.0.0/gems/railties-4.0.0/lib/rails/commands.rb:76:in `block in ' from /usr/local/lib/ruby/gems/2.0.0/gems/railties-4.0.0/lib/rails/commands.rb:73:in `tap' from /usr/local/lib/ruby/gems/2.0.0/gems/railties-4.0.0/lib/rails/commands.rb:73:in `' from bin/rails:4:in `require' from bin/rails:4:in `'

Find your sqlite3 gemspec file. One example is /usr/local/share/gem/specifications/sqlite3-1.3.7.gemspec
Windows: C:\Ruby21\lib\ruby\gems\2.1.0\specifications.
You should adjust according with your Rubygem path and sqlite3 version. Edit the file above and look for the following line
s.require_paths=["lib"]
change it to
s.require_paths= ["lib/sqlite3_native"]

see：https://stackoverflow.com/a/39136421/6755206
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
Build
- run command-line in the extracted dir
- make sure you have your C compiler installed and added to PATH
gem install bundlerbundle installrake 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

Uninstalling and reinstalling the sqlite3 gem worked for me.
gem uninstall sqlite3 bundle
回答4:
No compiling of the sources or downloading pre-compiled libraries will solve this problem, believe me I tried everything, the problem lies somewhere else. This is how it works on windows:
bundle update sqlite3
You likely get another similar error after this one regarding nokogiri, fix it with the command:
bundle update nokogiri
Enjoy your Ruby App!

If the top answer doesn't work, a fix that I discovered is simply going to your Gemfile and adding the version number 1.3.11 (instead of 1.3.9) right after sqlite3. So the line in your Gemfile should now read:
# Use sqlite3 as the database for Active Record gem 'sqlite3', '1.3.11'

This happened to me as well. It turned out that I had originally installed SQLite 1.3.10, but then I copied some gems from the Rails tutorial screencasts project and it listed SQLite 1.3.9. Then I got the same error you did. I changed it back to 1.3.10 and it worked.
(This is on Windows 7. I was running the screencast tutorial on Cloud9 IDE).
