Annoying libv8 error even after successful installation

OK. I am trying to load bootstarp for the first time, and I added the "therubyracer" and "less-rails" gems to my gemfile along with "twitter-bootstrap-rails". After

install package

I am getting the following error.

Bundler::GemspecError: Could not read gem at /home/addie/.rvm/gems/ruby-2.1.1/cache/libv8-3.16.14.3-x86_64-linux.gem. It may be corrupted.
An error occurred while installing libv8 (3.16.14.3), and Bundler cannot
continue.
Make sure that `gem install libv8 -v '3.16.14.3'` succeeds before bundling.

      

        
        
        
      

    

as they say I tried:

gem install libv8 -v '3.16.14.3'

and he is doing well.

Building native extensions.  This could take a while...

but when I try to install the package again, I get the same error as before:

Bundler::GemspecError: Could not read gem at /home/addie/.rvm/gems/ruby-2.1.1/cache/libv8-3.16.14.3-x86_64-linux.gem. It may be corrupted.

This is so annoying! Can someone please help me?

EDIT:

As most solutions for libv8 can be found, I have tried

gem install libv8 -v '3.11.8.17' - --with-system-v8

this succeeds too, but is irrelevant for the install error setting.
