Question

我一直在将Rails应用程序上传到Heroku

时出错

Installing therubyracer (0.11.0)
       Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
       /usr/local/bin/ruby extconf.rb

       Could not create Makefile due to some reason, probably lack of
       necessary libraries and/or headers.  Check the mkmf.log file for more

       from extconf.rb:22:in `<main>'
       The Ruby Racer requires libv8 ~> 3.11.8
       to be present on your system in order to compile
       and link, but it could not be found.
       In order to resolve this, you will either need to manually
       install an appropriate libv8 and make sure that this
       build process can find it. If you install it into the
       standard system path, then it should just be picked up
       automatically. Otherwise, you'll have to pass some extra
       flags to the build process as a hint.
       If you don't want to bother with all that, there is a
       rubygem that will do all this for you. You can add
       following line to your Gemfile:
       gem 'libv8', '~> 3.11.8'
       We hope that helps, and we apologize, but now we have
       to push the eject button on this install.
       thanks,
       The Mgmt.
       Gem files will remain installed in /tmp/build_3srt9ifqtbs6m/vendor/bundle/ruby/1.9.1/gems/therubyracer-0.11.0 for inspection.

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

Gem文件的一部分

gem 'libv8', '~> 3.11.8'
gem "therubyracer", :platforms => :ruby, :require => 'v8'
group :linux_test do
  #gem "therubyracer", :require => false
  gem "libnotify", :require => false
end
group :production do
  gem "therubyracer-heroku"
  gem "pg"
end

therubyracer和lib8是最新的，我现在重新安装它们。

我该如何解决？

P.S。 Ubuntu 12.1，x64。

在https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar查看Heroku Cedar上的Rails 3.1+资产管道：

therubyracer

如果您之前使用的是therubyracer或therubyracer-heroku，则不再需要这些宝石，因为这些宝石会占用大量内存，因此强烈建议不要这样做。

如果您的开发环境中需要therubyracer gem，请将其包装在一个组中：

group :development do
  gem 'therubyracer', :platforms => :ruby, :require => 'v8'
end

（Heroku不会安装仅位于development组中的宝石。）

无论如何，请将其从以下production组中删除。

在heroku安装therubyracer，无法构建gem原生扩展
