Cannot install sqlite3 and run bundle install - ruby-on-rails

Question

I'm working on a Ruby on Rails application with sqlite3 and when I run bundle install, I have this error:
Installing sqlite3 1.3.11 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing sqlite3 (1.3.11), and Bundler cannot continue.
Make sure that `gem install sqlite3 -v '1.3.11'` succeeds before bundling.
Gemfile
source 'http://rubygems.org'
gem 'rails', '3.0.5'
gem 'sqlite3-ruby', '1.3.2', :require => 'sqlite3'
Any ideas how I can fix this?

Answer 1

You need to install sqlite3 first sudo apt-get install libsqlite3-dev

Answer 2

Have you tried googling your error?
Here's an answer to the same error you're getting.
Unable to install gem - Failed to build gem native extension - cannot load such file -- mkmf (LoadError)
The solution is not with sqlite3. It's most likely your -dev package. If you're on Linux try this -
sudo apt-get install ruby-dev
For Mac, try this
brew install ruby-dev
