Failed to build gem native extension ruby racer gem of different version

问题

I copied the application from production and did bundle install to install all the missing gems that are in production version and not on my local machine.

Gem.lock file has the rubyracer version '0.10.1'. So when it tried to install this version using bundle install following error appeared.

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

I am not able to run the scaffolding commands on my production version of code from my local machine because of this error . Please help me out.

Can we edit the gemfile.lock to remove "therubyracer (0.10.1)" and then run the command generate scaffold and then place back the changes after my use of generate scaffold ?

In response to the following quote:

No we cannot. Dependent on what OS you are on you can do the following:

$gem uninstall libv8 
$gem install therubyracer

I have a rails application that I recently did and I too was running Rails 3.2.14 and had the following:

group :assets do
  gem 'therubyracer', :require => 'v8'
  gem 'less-rails'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

Should you go with this second method please before you add this asset block to your gemfile. Delete your Gemfile.lock and then add the asset block to the Gemfile, save it and run bundle update
