我刚刚将我的 Windows 2008 Server x64 机器更新为 ruby​​gems 1.5.0，现在我无法使用rake clobber buildGemcutter 提供的 rake 任务 () 构建 gem。我收到以下错误：

更新：#1239中有报告称升级到 bundler 1.0.21 或 1.1 可能会解决问题。（感谢 forforf 的指点！）

gem install bundler

这是 bundler 中的一个已知错误 ( #1239 )。Larschrequire 'psych'在 Rakefile 顶部添加的解决方法对我的 Rails 项目没有帮助（无论出于何种原因——它根本没有改变任何东西），但设置RUBYOPT='-rpsych'为一种解决方法，就像这样，解决了问题：

RUBYOPT='-rpsych' bundle install

（感谢 Moro指出这一点。）

它似乎只需要安装和更新。应用程序本身（即调用 rake 等，即使使用bundle exec）应该在不设置 RUBYOPT 的情况下继续运行。

作为背景，仅仅需要 psych 模块会有所不同的原因似乎是这样的：YAML自动使用（较旧的）Syck 库，除非在需要 YAML 时加载了 Psych，在这种情况下它使用 Psych。这种隐含的行为，当然会带来很多麻烦，包括我们这里看到的问题。

这个 Hoe 错误报告描述了一种解决方法：在 Rakefile 中的任何其他内容之前添加 require 'psych'。为我工作。

我在尝试以 Puma 作为服务器运行 rails 应用程序时遇到了这个问题。答案原来是这里的人所说的，即如果没有指定，Ruby 将尝试使用 syck（旧的 yaml 解析器）而不是 psych（新的 yaml 解析器）。我不得不config/boot.rb用以下几行修改文件：

require 'psych'
YAML::ENGINE.yamler = 'psych'

强制它停止使用 syck 并切换到 psych。之后一切正常。
