安装therubyracer时出错

Question

I am receiving an error while bundle install my updates. Here is my gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.1'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'mysql2'
gem 'libv8'
gem 'therubyracer'
gem 'haml'
gem 'haml-rails'
gem 'sass-rails',   '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'compass-rails'
gem 'chosen-rails'
gem "bootstrap-wysihtml5-rails", "~> 0.3.1.10"
gem 'hpricot'
gem "rest-open-uri", "~> 1.0.0"
gem 'jquery-datatables-rails', github: 'rweng/jquery-datatables-rails'

# Gems used only for assets and not required
# in production environments by default.
group :assets do

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer'

  gem 'uglifier', '>= 1.0.3'
  gem "commonjs", "~> 0.2.6"
  gem "less", "~> 2.2.2"
  gem "less-rails", "~> 2.2.6"
end


gem 'jquery-rails'
gem 'simple_form'
gem 'client_side_validations'
gem 'client_side_validations-simple_form'

# To use ActiveModel has_secure_password
gem 'bcrypt-ruby', '~> 3.0.0'

Here is an error i am getting after running bundle install command on production:

An error occured while installing therubyracer (0.11.0), and Bundler cannot continue. Make sure that gem install therubyracer -v '0.11.0' succeeds before bundling.

Answer 1

I did the following that worked for me:

• I commented out therubyracer from my Gemfile
• ran "bundle install"
• installed the newest version of therubyracer using "gem install therubyracer" (at the time of writing this is 0.11.2)
• I uncommented therubyracer to put it back in to my Gemfile
• ran "bundle install" again and everything works

Answer 2

Including libv8 in the Gemfile seems to be a fix to that:

gem 'libv8', '~> 3.11.8.3'

via https://github.com/cowboyd/therubyracer/issues/215

Answer 3

我做了一个gem卸载therubyracer＆gem卸载libv8，然后从gemfile中删除libv8并只使用therubyracer，然后运行'bundle install'

Answer 4

group :assets do
  gem 'therubyracer'
end

If it still does not work, just try to intall NodeJS

Answer 5

probably, your libv8 version and therubyracer version are not matching.

So, either you can include proper libv8 version in the Gemfile, which is similar to the jibiel's solution

gem 'libv8', '~> 3.11.8.3'

But, I would prefer to do these two steps, So, that you don't have to worry about finding proper version of libv8:

Gemfile

gem 'therubyracer'

terminal

gem uninstall libv8
bundle install

And, that is what I have done to solve my same problem
