Can't start rails server because "Could not find json-1.8.1 in any of the sources"

Question

ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]

Rails 4.0.0

Bundler version 1.7.9

When I go to my project folder and run 'rails server' I get the following error:

Could not find json-1.8.1 in any of the sources
Run `bundle install` to install missing gems.

When I run 'bundle install' it does something but then give the following error:

An error occurred while installing json (1.8.1), and Bundler cannot continue. 
Make sure that `gem install json -v '1.8.1'` succeeds before bundling.

When I run gem install json -v '1.8.1' I get the following error:

Error installing json:
        ERROR: Failed to build gem native extension.
Gem files will remain installed in /var/lib/gems/1.9.1/gems/json-1.8.1 for inspection.

gem install json -v '1.8.1' -V

Can please someone help me with this problem?, thank you!

You are probably missing some dependency/library, but with the current information that is unclear. Please run `gem install json -v '1.8.1' -V` (notice the extra `-V` flag) in order to get verbose output, so the actual problem is hopefully shown. And update/edit your question to add this new information. — Veger, Dec 17 '14 at 10:10

According to this answer you need the ruby development package (ruby-dev).

If you use Debian/Ubuntu you can install it using

sudo apt-get install ruby-dev

If not, you need corresponding command to install the package for your OS.

Thank you so much Veger. The solution in the comments 'sudo apt-get install ruby-dev' helped me. After that i did 'bundle install' and the rails server is working!! – Kronos Dec 17 '14 at 10:38

Can't start rails server because "Could not find json-1.8.1 in any of the sources"
