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

最佳答案

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

gem install bundler

---

这是 bundler 中的一个已知错误 (#1239)。 Larsch 在 Rakefile 顶部添加 require 'psych' 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)，但是设置 RUBYOPT ='-rpsych' 作为解决方法，像这样解决了问题:

RUBYOPT='-rpsych' bundle install

(感谢 Moro 提供 pointing this out。)

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)也应该在不设置 RUBYOPT 的情况下继续运行。

---

作为背景，简单地要求 psych 模块的原因似乎是这样的:YAML automatically使用(较旧的)Syck 库，除非在需要 YAML 时加载 Psych，在这种情况下它使用 Psych。这种隐式行为当然会导致 a lot of trouble ，包括我们在这里看到的问题。

关于ruby - GemCutter rake build 现在抛出 "undefined method ' write' for #<Syck::Emitter:...."在 Windows 上的 ruby​​ 1.9.2 上更新到 ruby​​gems 1.5.0 之后，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/4932881/
