Guard在Windows 7（64位）上给出错误

嗨社区成员，我是ruby的新手，我正在尝试学习rspec，并且正在使用guard运行rspec示例。

我在发出命令之前尝试运行一个简单的rspec示例（通过设置以下环境）守卫观察rspec资源

ruby-1.9.3p545
rspec-3.0.0
guard-2.6.2
guard-rspec-4.2.9

请在此处说明问题所在。我非常感谢你的帮助。

我遇到了同样的问题。

看起来这可能是今天发布的listen 2.7.6版本的问题。尝试手动安装listen 2.6.5：

如果你正在使用bundler：

gem 'listen', '2.7.5'

如果您使用rubygems安装：

gem uninstall listen
gem install listen -v 2.7.5

编辑：对于任何googlers，版本2.7.9现已推出，使得这个答案过时。
