在使用guard-rspec 在Rails 4 项目中运行guard 时，我在vim 中打开/关闭文件时偶尔会看到以下错误。我试过升级/降级guard、guard-rspec、pry和其他库，但没有运气。

  • ruby 2.0.0p247（2013-06-27 修订版 41674）[x86_64-linux]
  • 捆绑器版本 1.3.5
  • 守卫版本 2.1.1

以下是我每隔几次测试运行看到的堆栈跟踪：

将rb-readline gem 添加到我的 Gemfile 似乎可以解决问题。

gem "rb-readline", "~> 0.5.0"

我的猜测是 Ruby 2.0.0-p247 的 rbenv 编译版本存在 readline 问题，这解释了为什么在pry_instance.rb:624:in 'readline'. rb-readline 项目是 readline 库的纯 ruby​​ 实现，似乎可以缓解这个问题。

可能有更好的解决方案涉及重新编译 ruby​​，但我还没有找到。

这似乎是 Ruby 2.0.0 和 1.9.3 中的一个错误。见https://bugs.ruby-lang.org/issues/8669

它在修订版 42216 中向后移植到 Ruby 2.0.0。

你在使用 Sublime Text 3 吗？如果是的话，你一定要看看这个！

TLDR：设置"atomic_save": false。
