sqlite - Rails 4.0rc1 app not running due to missing sqlite3 gem -


first time i've tried installing rails 4.0. on windows 8 ruby 2.0 x64. ran:

gem install rails --version 4.0.0.rc1 --no-ri --no-rdoc

then run:

rails new test_app cd test_app rails s

but webpage @ localhost:3000 reports following error:

specified 'sqlite3' database adapter, gem not loaded. add gem 'sqlite3' gemfile.

it's there in gemfile:

gem 'sqlite3'

i tried running bundle install several times , doesn't list among other gems.

update: i've tried installing sqlite3 gem in 2 different ways, both using terminal opens msys.bat file devkit. way @szines below mentions gives me following error:

$ gem install sqlite3 --platform=ruby -- --with-opt-dir=c:/sqlite-amalgamation-3071602 temporarily enhancing path include devkit... building native extensions with: '--with-opt-dir=c:/sqlite-amalgamation-3071602' take while... error:  error installing sqlite3:         error: failed build gem native extension.      c:/ruby200-x64/bin/ruby.exe extconf.rb --with-opt-dir=c:/sqlite-amalgamation-3071602 checking sqlite3.h... yes checking sqlite3_libversion_number()... -lsqlite3 sqlite3 missing. install sqlite3 http://www.sqlite.org/ first. *** extconf.rb failed *** not create makefile due reason, lack of necessary libraries and/or headers.  check mkmf.log file more details.  may need configuration options.  provided configuration options:         --with-opt-dir         --with-opt-include         --without-opt-include=${opt-dir}/include         --with-opt-lib         --without-opt-lib=${opt-dir}/lib         --with-make-prog         --without-make-prog         --srcdir=.         --curdir         --ruby=c:/ruby200-x64/bin/ruby         --with-sqlite3-dir         --without-sqlite3-dir         --with-sqlite3-include         --without-sqlite3-include=${sqlite3-dir}/include         --with-sqlite3-lib         --without-sqlite3-lib=${sqlite3-dir}/         --enable-local         --disable-local         --with-sqlite3lib         --without-sqlite3lib   gem files remain installed in c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/sqlite3-1.3.7 inspection. results logged c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/sqlite3-1.3.7/ext/sqlite3/gem_make.out

the other way, use autoconf package sqlite.org , able compile , install sqlite3 gem. however, when try open rails server following error:

c:\users\me\rubymineprojects\my_project>rails s c:/ruby200-x64/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)         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/sqlite3-1.3.7/lib/sqlite3.rb:6:in `rescue in <top (required)>'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/sqlite3-1.3.7/lib/sqlite3.rb:2:in `<top (required)>'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:72:in `require'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:72:in `block (2 levels) in require'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:70:in `each'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:70:in `block in require'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:59:in `each'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/runtime.rb:59:in `require'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler.rb:132:in `require'         c:/users/me/rubymineprojects/my_project/config/application.rb:7:in `<top (required)>'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/railties-4.0.0.rc1/lib/rails/commands.rb:78:in `require'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/railties-4.0.0.rc1/lib/rails/commands.rb:78:in `block in <top (required)>'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/railties-4.0.0.rc1/lib/rails/commands.rb:75:in `tap'         c:/ruby200-x64/lib/ruby/gems/2.0.0/gems/railties-4.0.0.rc1/lib/rails/commands.rb:75:in `<top (required)>'         bin/rails:4:in `require'         bin/rails:4:in `<main>'

pretty annoying, got working. have following:

  1. download sqlite files ready compiled luis lavena (this x64)
  2. unarchive 7-zip maybe `c:\sqlite3
  3. run msys.bat within devkit folder unarchived devkit to
  4. run gem install sqlite3 --platform=ruby -- --with-opt-dir=c:/sqlite3
