Gem files will remain installed in /home/duke/.rvm/gems/ruby-2.1.8/gems/therubyracer-0.10.2 for inspection.

I tried some other answers on related questions but nothing helps me. I am out of solutions.

Answer 1

This package contains the header files needed for extension libraries for Ruby 1.9.1. You need to install the ruby1.9.1-dev package by doing:

sudo apt-get install ruby1.9.1-dev

Generally it's easier to just do:

sudo apt-get install ruby-dev

Answer 2

I think that your problem is libv8 , so you should uninstall libv8 via command as bellow:

gem uninstall libv8

Then run gem install therubyracer -v '0.10.2' again. It will work.
