在 Windows 上，是的，node.js 已安装。

我刚刚按照视频教程在 Rails 上安装了 ruby​​，但是当我运行 rails server 时出现此错误：

c:/row/Ruby21/lib/ruby/gems/2.1.0/gems/bundler-1.11.2/lib/bundler/runtime.rb:80:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'uglifier'. (Bundler::GemRequireError)

        from bin/rails:4:in `<main>'

我的 gemfile 中确实有 uglifier 已安装 uglifier，并且 bundle install 显示正在使用 uglifier。

问题可能是什么？

好像您没有安装 uglifier 需要的 JS 运行时。你可以安装 nodejs。

在 Ubuntu 上这样做的方式：

sudo apt-get update
sudo apt-get install nodejs
