Answer 1

In some case, you have not installed therubyracer.

add

#gem 'therubyracer' , '= 0.10.2'

to your Gemfile and

#bundle install

may resolve this problem. (In my case, I could not make the rubyracer 0.11.0, so I designated 0.10.2)

If you have not installed libv8, you have to exec

#gem install libv8 --version=3.11.8.3

or something like this before hand.
