Why can't I get sqlite installed? - ruby-on-rails

When I go to install using "sudo bundle install" to install all of them...it throws an error on sqlite3:
Installing sqlite3 (1.3.3) with native extensions /Library/Ruby/Site/1.8/rubygems/installer.rb:533:in `build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

Then I think maybe I have it already installed because i've used it before...but when I do "rake db:create" it gives me this:
Could not find gem 'sqlite3 (>= 0)' in any of the gem sources listed in your Gemfile.
What am I doing wrong?

Make sure you have XCode installed. The necessary header files should be installed by that.
Also, unrelated advice, stop using sudo. Look into installing RVM. It will make your life easier.
Related question: Snow Leopard & Ruby on Rails - SQLite3 issue

You may be missing the sqlite3.dll file. Go to the bin folder in your ruby folder and look for a sqlite3.dll file. If you can't find it there then download it for http://www.sqlite.org/download.html. Then put the dll file in your bin(ruby's bin) folder and run bundle install again and see if that works.

Any suggestions on what I should do or how I can fix this?
Try running this:

& then run bundle install again

I typed heroku keys:add then I got these errors.

Could you please let me know how to fix it.
Thanks
Try installing the gem again with the right spelling:
gem install heroku
Check the version of the ruby you are using with
rvm list
ruby -v
gem list
You need to switch to the right ruby with
rvm use <ruby version>
And then install heroku again.
Get Home Brew then run the command "brew doctor". If it tells you that you have errors, fix those errors.
I'm guessing you are on a Mac and that you might be running MacPorts. There are problems with this because MacPorts uses older libs that rvm tries to access. You need to remove opt and a bunch of stuff from your paths where brew doctor complans.

I've seen the answer at nokogiri - ERROR: Failed to build gem native extension but I have Xcode 4.3.2 running.
Any ideas? Thanks
For OS 10.7 + XCode4.3 only open Xcode preferences, select the
"Downloads" button, select the "Components" tab of Downloads, highlight
"Command Line Tools" and press the install button.

RMagick fails to install using bundler, installs correctly using RubyGems

On my Ubuntu 10.04 machine I'm having some issues installing RMagick (Ruby's ImageMagick gem), both with the regular imagemagick packages from apt and with ImageMagick compiled from source.
The issue so far is that bundle install fails to install rmagick, whereas RubyGems works just fine. My output is the following:

And also installing using RubyGems works just fine on this machine, making it hard to localize the actual error:

I'm definitely hoping anyone has some pointers. The behavior found looks a lot like the issue in curb gem installation: bundle install fails, but normal gem install works, sadly this issue has no solution posted (and I'm not short on memory). Thanks in advance!
I've been unable to find any solution for the issue and instead installed rvm, which did work correctly.

I don't understand why bundler is having such a problem with this. I'm running bundler 1.0.7.
Please help because json 1.4.6 has to be included as a dependency for another vital gem.
It's very possible that the Ubuntu provided Ruby or RubyGems is broken. I really recommend you install Ruby using RVM, as described in this post: Ubuntu, Ruby, RVM, Rails, and You.
If you still have trouble with the json gem even after using rvm, it'll likely be much easier to debug as you'll be using something closer to what most other Rubyists do.
I had the same issue as Simon in Ubuntu 12.04 with stock ruby 1.8. I was trying to install Redmine and Bundler (sudo bundle install) kept failed withthe same error when building the json gem. sudo gem install json worked just fine, so I did that and then installed the rest of the app's requirements with Bundler. Hope this helps someone.
