Question

I get this error when running cap:deploy

I already run apt-get update and apt-get upgrade

I already ran bundle install, added Gemfile and Gemfile.lock to the repository.

Answer 1

I would recommend installing rvm here – as Joshua Cheek said, the problem appears to be with the ruby binary, which should be helped by rvm.

Do apt-get install rvm, then once it is installed run rvm list known to give you a list of the available ruby versions; install the one you want with rvm install (version) then rvm use (version) (exclude brackets).

Doing this will ensure you have a clean install of ruby, with available ruby command and a clean gemset.

You should then be able to do apt-get install libv8 – if you are still having a problem, do an edit with the error message and we’ll go from there.
