Question

我不是红宝石专家，但我已设法收集足够的信息来设置Gemfile并安装所需的Gemfiles。

然而，最近，我遇到了一些问题。无论出于何种原因，我现在收到此错误：

> bundle install --deployment
      Unfortunately, a fatal error has occurred. Please see the Bundler
      troubleshooting documentation at http://bit.ly/bundler-issues. Thanks!

我看过recommended link，但问题仍然存在。我的Gemfile非常简单：

source "https://rubygems.org"
gem 'sass'

随附的Gemfile.lock：

GEM
  remote: https://rubygems.org/
  specs:
    sass (3.2.6)

PLATFORMS
  ruby

DEPENDENCIES
  sass

为什么bundler无法安装？

更多详情：
使用较旧版本的bundler（比方说，1.2），效果很好。只是不 1.3.1

我正在使用ruby 1.8.7和rubygems 1.8.11。

当您安装ruby时，您没有在系统上安装libyaml。 Ruby需要libyaml才能使用它的standardlib yaml库。

尝试安装libyaml（查找如何为您的特定操作系统），然后重新安装ruby。

Answer 2

刚刚遇到同样的问题并通过卸载最新的捆绑软件版本1.3.1

解决了这个问题

gem uninstall bundler -v 1.3.1

bundler 1.3.0 应该让它通过;）

编辑：不知道为什么：|

`bundler install --deployment`缺少`to_yaml`？
