Error for command - rails server - cannot load such file — sqlite3/sqlite3_native (LoadError)

Question

I apologize if this question is redundant but I haven't been able to fix my problem with the suggestions I have found on here and on other sites. I am new to Ruby,Rails and many concepts that seem to be important for getting everything installed and running correctly.

I am on a mac OS 10.9. What I have installed is: ruby 2.0.0, Rails 4.0.2, rubygems 1.8.25. I have followed Hartl tutorial exactly from the beginning up until the point where I first call rails server and then I receive this error message:

Macintosh-0025bce1e74a:first_app johns$ rails server

I had installed sqlite3 prior to starting the rails tutorial so I thought perhaps that could possibly be related to the problem but I am not educated about paths and how to figure out if that is the problem.

Macintosh-0025bce1e74a:~ johns$ sqlite3 --version 3.7.13

From what I have read my computer will go through PATH to find the executable binaries needed to run a program and my PATH is as follows:

Macintosh-0025bce1e74a:~ johns$ echo $PATH /usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin

my gemfile is

source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0

gem 'rails', '4.0.2'

group :development do
  gem 'sqlite3', '1.3.8'
end

gem 'sass-rails', '4.0.1'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.1'
gem 'jquery-rails', '3.0.4'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'

group :doc do
  gem 'sdoc', '0.3.20', require: false
end

I did remember to run bundle update, bundle install.

Thanks so much for any help!

EDIT I think I got it working by finally understanding how to perform the steps laid out in a link someone posted in a previous question of this nature

http://ahmedemad.wordpress.com/2013/05/17/ruby-on-rails-install-run-error/

EDIT It didn't work, the rails server command went through okay but when I tried to pull up the page I got another error:

undefined method `busy_timeout' for #SQLite3::Database:0x007fccb3e10438>

EDIT I tried another suggestion I found but it produced the same error when I tried to visit the site.

I edited the /sqlite3-1.3.8.gemspec and changed s.require_paths=["lib"] to s.require_paths= ["lib/sqlite3_native"] which apparently did the trick for some one.

EDIT got rvm and reinstalled things, had another go at it and it now works...weird

Answer 1

I find it interesting that this error is exactly the same as this: Repairing Rails and Server and on Nitrous.io

The answer suggests simply reinstalling rails by running:

gem install rails

And then bundle install in your project's directory to make sure everything's up to date.

Answer 2

If you install sqlite3 from source. You should enable the option SQLITE_ENABLE_COLUMN_METADATA at the configure time.

./configure CPPFLAGS='-DSQLITE_ENABLE_COLUMN_METADATA' CFLAGS='-DSQLITE_ENABLE_COLUMN_METADATA'
