Are all dependencies met ? Does `bundle update` help you? What is the exact version of the libv8 you have installed? 3) (slightly off-topic) How to avoid these issues altogether ? This may be off-topic for your specific question, but in general, I find it easier to set-up a dev server on Ubuntu 10.x, 11.x with rvm. I published my recent experiences here: http://rails.vandenabeele.com/blog/2011/11/26/installing-ruby-and-rails-with-rvm-on-ubuntu-11-dot-10/ Regarding the set-up of "therubyracer", this is how it worked in the rvm environment: <quote> ~/data/git/NewProject$ echo "gem 'therubyracer'" >> Gemfile ~/data/git/NewProject$ bundle install Fetching source index for http://rubygems.org/ ... Installing libv8 (3.3.10.4) ... Installing therubyracer (0.9.9) with native extensions ... Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed. </quote> and that worked out of the box.
