问题描述
自从 Dreamhost 几周前升级了他们的服务器后，我的网站就被破坏了.我一直在努力修复它并取得了一些进展，但我仍然坚持希望是最后一个问题.
My website has been broken since Dreamhost upgraded their servers a couple of weeks ago. I have been tearing my hair out trying to get it fixed and made some progress but am stuck on what is hopefully the final issue.
我在 Ruby 1.8.7 上使用 Rails 3.1.1，并收到来自 PhusionPassenger 的Ruby (Rack) 应用程序无法启动错误".它声明它找不到 JavaScript 运行时".有关可用运行时的列表，请参阅 https://github.com/sstephenson/execjs.(ExecJS::RuntimeUnavailable)'.在 Dreamhost 的 wiki 上搜索此内容已建议安装therubyracer" gem 的解决方案.
I'm using Rails 3.1.1 on Ruby 1.8.7 and get presented with a 'Ruby (Rack) application could not be started error' from PhusionPassenger. It states that it 'Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes. (ExecJS::RuntimeUnavailable)'. Searching for this on Dreamhost's wiki has suggested a solution to install 'therubyracer' gem.
所以我用建议的 gem 更新了我的 gemfile，如下所示:
So I updated my gemfile with the suggested gem like so:
宝石 'therubyracer', '~> 0.9.9'
gem 'therubyracer', '~> 0.9.9'
我也尝试添加到文件中:
I have also tried adding to the file with:
gem 'therubyracer', :platforms => :ruby
gem 'therubyracer', :platforms => :ruby
但它并没有产生任何影响.
but it hasn't made a difference.
然后捆绑安装在我的 Macbook(运行 OS X 10.5.8)上.但是，当我运行cap deploy"来安装 Dreamhost 时，这会失败；我在尝试安装 therubyracer 所依赖的 libv8 时看到错误.
Then bundle installed on my Macbook (running OS X 10.5.8) without hitch. However, this fails when I run 'cap deploy' to put on Dreamhost; I see an error when it attempts to install libv8 which therubyracer depends on.
有人知道如何正确安装它或任何其他有效的解决方案吗?
Anyone know how to get this to install correctly or any other working solution?
可应要求提供任何其他信息.
Any other info can be provided upon request.

推荐答案
libv8 是一个操作系统库；您需要安装正确的 Linux 系统库.如果你运行的是 Ubuntu，它是
libv8 is an OS library; you'll need to install the correct Linux system library. If you're running Ubuntu, it's
sudo apt-get install libv8-dev
或者，您可以安装 node.js，它可以作为 Debian/Ubuntu 软件包用于各种发行版，例如http://ppa.launchpad.net/chris-lea/node.js/ubuntu
Alternatively, you can install node.js which is available as a Debian/Ubuntu package for various distros, e.g. http://ppa.launchpad.net/chris-lea/node.js/ubuntu
通过在 Heroku 上进行部署，您可以省去很多麻烦，而无需为 gems 管理操作系统或组件.
You may save yourself a lot of trouble by deploying on Heroku instead where you don't have to manage the OS or components for gems.
