Error installing libv8: ERROR: Failed to build gem native extension

Question

I made a rails project with,

rails new test_bootstrap.

succeeded.

moved to the project dir and added the gems

gem \         


        

Answer 1

My issue wasn't related with therubyracer at all just libv8 gem and as @rishav-bhardwaj pointed --with-system-v8 didn't do the trick, instead i had to exec

bundle update

then

bundle install

and finally

Bundle complete!

The error is gone!

Gem::Ext::BuildError: ERROR: Failed to build gem native extension. An error occurred while installing libv8 (3.16.14.7), and Bundler cannot continue. Make sure that `gem install libv8 -v '3.16.14.7'` succeeds before bundling.
