on "Debian GNU/Linux 6.0" its "ruby1.9.2"<br>
after that, need to:
 apt-get install rubygems

:curious, the Debian packages page tells me that “This package provides Rubygems for Ruby 1.8. In Ruby 1.9.X, Rubygems is provided with the interpreter.” --[[User:Nomaster|Nomaster]] ([[User talk:Nomaster|talk]]) 09:58, 24 October 2012 (CEST)

 An error occurred while installing sqlite3 (1.3.6), and Bundler cannot continue.
 Make sure that `gem install sqlite3 -v '1.3.6'` succeeds before bundling.

 gem install sqlite3 -v '1.3.6'

Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3:
	ERROR: Failed to build gem native extension.

checking for sqlite3.h... no
sqlite3.h is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite-devel' and check your shared library search path (the
location where your sqlite3 shared library is located).
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

:You need to install the SQlite development headers in package <tt>libsqlite3-dev</tt>. --[[User:Nomaster|Nomaster]] ([[User talk:Nomaster|talk]]) 10:00, 24 October 2012 (CEST)

 apt-get install libsqlite3-dev

== JavaScript runtime error ==

Does your application give the following error message at start?

  Could not find a JavaScript runtime.

You can fix this by installing a pure Ruby JavaScript interpreter, which is an easy way across all platforms. To do this, add the following line to the <tt>Gemfile</tt>.

  gem 'therubyracer'

...and let Bundler handle the rest

  $ bundle install
