Being really new to Ruby/Rails, and after attempting to resolve the issue myself this weekend I'm making an attempt to seek advice here.

I have a complete Ruby/Apache/Passenger setup done on FreeBSD, and I'm trying to accomplish the task of using Windows as a Ruby development environment.

So far:

  • Ruby is installed, v2.0.0p0 (2013-02-24) [x64-ming32]
  • Rails is installed, v.3.2.12
  • I have the Ruby dev kit installed and registered.
  • I have the sqlite3 dll/exe copied to the Ruby "bin" folder (which is also in my path using the "Start Command Prompt with Ruby" console.)
  • I can start a rails server successfully, and continuing with the http://guides.rubyonrails.org/getting_started.html tutorial to 3.3.
  • ">rake db:create" tells me:

    Please install the sqlite3 adapter: gem install activerecord-sqlite3-adapter ( sqlite3 is not part of the bundle. Add it to Gemfile.)

which I have no "understanding" of. Trying to install activerecord-sqlite3-adapter gives me a "Could not find a valid gem..."

  • ">gem install sqlite3" returns:

    Building native extensions. This could take a while... ERROR: Error installing sqlite3: ERROR: Failed to build gem native extension.

    D:/Development/Ruby200-x64/bin/ruby.exe extconf.rb checking for sqlite3.h... *** extconf.rb failed ***

Right now I'm stuck at the point where I don't even know what state my Ruby on Windows installation is in. I'm trying to follow the main Rails tutorial and it doesn't specify any of these issues (probably because Ruby on Windows seems to be a natural pain for a lot of people.)

What am I missing?!? I'm just trying to install sqlite3 for Ruby on Windows, seems simple right?

If I do ">rais db" the SQLite shell is presented:

SQLite version 3.7.15.2 2013-01-09 11:53:05

The 'unanswered question' actually has an accepted answer. Have you tried putting the sqlite.dll in your ruby/bin directory? - PinnyM
You are using an x64 ruby, the .dll is probably 32-bit and can't be used. You can try the x64 build of the .dll mentioned here. - PinnyM
I don't know what the SO etiquette is for this, but I dropped a version of Ruby to 1.9.x, and ">gem install sqlite3" worked without issue. - chrisp
I believe I followed your hint and specifically ensured I downloaded the 32bit version of Ruby. While I do understand that I can submit my own answer, the issue is, that it's not "the" answer. Version requirements are not discrete for me at this time, but downgrading seems like a "dirty" solution. - chrisp
You don't need to downgrade - you can install 32-bit version of ruby 2.0 or use the 64-bit version of the .dll. RE: json gem, what error are you seeing? - PinnyM

Even though the question has been answered, I want to post my research to help others. I found a lot of information online, but being a Ruby newbie I had a tough time following all. The basic answer comes from the following post https://github.com/luislavena/sqlite3-ruby/issues/82 with instructions by "paulwis" on how to properly install sqlite3 for ruby 2.0.0-p0 and some comments on https://github.com/rails/rails/issues/10150 . So here it is:

  1. Install the Ruby Devkit for your setup (DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe for me since I use a x64 machine)
  2. Download and extract the autoconf package from Sqlite.org
  3. Run msys.bat (it is inside the ruby devkit root folder)
  4. cd into the path where you downloaded the sqlite source (for example: "cd /c/dev/sqlite3" for path "c:\dev\sqlite3" if you are new to MSYS/MINGW32)
  5. Run "./configure"
  6. Run "make"
  7. Run "make install"
  8. Get the sqlite3 gem again, this time specifying the platform and the path to the newly compiled binaries:

    gem install sqlite3 --platform=ruby -- --with-sqlite3-include=[path\to\sqlite3.h] --with-sqlite3-lib=[path\to\sqlite3.o]
    

    For example:

    gem install sqlite3 --platform=ruby -- --with-sqlite3-include=/c:/dev/sqlite3/ --with-sqlite3-lib=/c:/dev/sqlite3/.libs/
    

    (from the paths given in step 4)

  9. Check the Gemfile.lock of your rails app and make sure that it points to the correct sqlite3 version. Mine was "sqlite3 (1.3.7-x86-mingw32)" and manually changed it to "sqlite3 (1.3.7-x64-mingw32)". Removing the platform also works: "sqlite3 (1.3.7)".

Hope this helps someone.

I was able to install sqlite3 with ruby2.0.0 on win XP32 with following command:

c:\>gem install sqlite3 --platform=ruby -- --with-sqlite3-dir=C:/distr/sqlite --with-sqlite3-include=C:/distr/sqlite

Folder C:/distr/sqlite contains following files

  • shell.c
  • sqlite3.c
  • sqlite3.h
  • sqlite3ext.h
  • sqlite3.def
  • sqlite3.dll

So, basically I've extract sqlite-amalgamation-3071602.zip and sqlite-dll-win32-x86-3071602.zip to C:/distr/sqlite.

HEADS UP

You still need to put copy of sqlite3.dll and sqlite3.def somewhere to PATH. IMHO it's best to keep sqlite3 binaries in ruby's bin folder.

This is an old thread, but still relevant.

For us it was as simple as editing the Gemfile and adding a specific version for sqlite.

gem 'sqlite3', '~> 1.3.13'

#!/usr/bin/env sh

mkdir c:/sqlite3x86
wget -P c:/sqlite3x86 http://packages.openknapsack.org/sqlite/sqlite-3.7.15.2-x86-windows.tar.lzma
cd c:/sqlite3x86
bsdtar --lzma -xf c:/sqlite3x86/sqlite-3.7.15.2-x86-windows.tar.lzma
gem install sqlite3 --platform=ruby -- --with-opt-dir=c:/sqlite3x86
cd c:/
rm -rf c:/sqlite3x86

For windows, go to C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/sqlite3-1.3.13-x64-mingw32/lib/sqlite3.rb

and make sure

require "sqlite3" instead of native

Get the fat binary from here

https://ci.appveyor.com/project/MSP-Greg/sqlite3-ruby/build/3/job/hhk6ie8gdo545svr/artifacts

and

gem install c:\path\to\downloaded_gem.gem

I figured I'd put in an answer -- from the comments, for posterity's sake. The issue seemed to be that I grabbed a new version of Ruby/Rails (for Windows) that was not compatible "yet" with SQLite3.

I downgraded to 1.9.x and was able to things running.

The easiest way to get set up for Ruby on Rails on a Windows machine is by using the RailsInstaller, which automatically installs and configures sqlite3 for you. One step.

You should follow this procedure:

  1. gem install bundler (add in Gem file_)
  2. gem 'sqlite3', ' < 1.4'(add in Gem file_)

then run:

install bundler
