Guard 在 Windows 7（64 位）上出现错误

社区成员您好，我是 ruby​​ 新手，我正在尝试学习 rspec，并正在使用 guard 运行 rspec 示例。

我正在尝试在发出命令之前运行一个简单的 rspec 示例（通过设置以下环境） 守望rspec资源

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

请提出这里有什么问题。 非常感谢您的帮助。

我遇到了同样的问题。

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

如果您使用捆绑器：

gem 'listen', '2.7.5'

如果您使用 ruby​​gems 安装：

gem uninstall listen
gem install listen -v 2.7.5

编辑：对于任何谷歌员工，2.7.9 版现已发布，这使得这个答案过时了。
