嗨，我是 Rails 的新手，我最近刚刚在 Ubuntu 12.04 上使用 RVM 设置了一个生产环境。如果重要的话，我已经在多用户模式下安装了 ruby​​（rvm 位于 /usr/local/rvm/bin/rvm）。

我正在设置 Capistrano 来部署我的 Rails 应用程序。除了包含任何 CoffeeScript 文件外，一切都很好。作为部署过程的一部分，Capistrano 运行 rake assets:precompile。这在我的本地环境（osx）上工作得很好，但在我的 ubuntu 上失败了。我已经安装了我认为需要的所有 gem（coffee-script coffee-script-source）。但它仍然不起作用。这里有任何指示吗？

尝试将此添加到您的 Gemfile 中：

gem "therubyracer"

根据我的经验，与 OSX 不同的 Ubuntu 中需要 JavaScript 解释器。

希望这可以帮助！

因此，经过大量挖掘，我意识到这个文件的长度为 0：

/usr/local/rvm/gems/ruby-1.9.3-p429/gems/coffee-script-source-1.6.2/lib/coffee_script/coffee-script.js

这只是通过从普通用户运行它来解决的：

rvmsudo gem pristine --all

我在互联网上环顾四周，我是唯一遇到此特定错误的人。我不知道这个文件是如何被截断的。我希望这对其他人有帮助。
