I have installed ruby on rails using rvm . I am trying to bundle install an older project that I had on a former pc but I get the following error when I run the bundle install command:

Installing json 1.8.3 with native extensions

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing json (1.8.3), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.3'` succeeds before bundling.

Reading the internet I tried installing all the dev things like :
sudo apt-get install libpq-dev

sudo apt-get install libmysqlclient-dev
sudo apt-get install libpq-dev
sudo apt-get install libsqlite3-dev
sudo apt-get install libev-dev

but it didn't work.
