“`bundler安装--部署--缺少`to_yaml`？”

Question

我不是一个红宝石专家，但我已经设法收集足够的信息，以建立一个Gemfile和安装所需的Gemfile。

然而，最近我遇到了一些问题。不管出于什么原因，我现在得到了这个错误：

> bundle install --deployment
      Unfortunately, a fatal error has occurred. Please see the Bundler
      troubleshooting documentation at http://bit.ly/bundler-issues. Thanks!
/usr/lib/ruby/gems/1.8/gems/bundler-1.3.1/lib/bundler/settings.rb:129:in `set_key': undefined method `to_yaml' for {"BUNDLE_FROZEN"=>"1"}:Hash (NoMethodError)

我已经看过推荐链接了，但问题仍然存在。我的Gemfile非常简单：

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

以及伴随的Gemfile.lock

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

PLATFORMS
  ruby

DEPENDENCIES
  sass

为什么邦德勒没有安装？

进一步详细信息

使用更旧版本的bundler (例如，1.2)，效果很好。只是没有1.3.1

我使用ruby 1.8.7和rubygems 1.8.11。

Answer 1

刚刚有了同样的问题，并通过卸载最新版本1.3.1解决了它

gem uninstall bundler -v 1.3.1

bundler 1.3.0应使其通过;)

编辑:不知道为什么：

Answer 2

任何机会，当你安装红宝石，你没有安装libyaml的系统。Ruby需要libyaml来运行它的标准库yaml。

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