在Windows 7 64位上失败，对于我来说:

我需要以特定的方式开始通知吗?我错过了什么?

RKing已经向Guard提交了一个问题，并将您的问题与它联系起来。看起来这要么是最新的Pry问题，要么是Guard没有正确使用Pry API。

我想到了两件事来解决这个问题:

1. 禁用交互器

   由于Pry仅在交互器中使用，所以您可以在启动Guard时禁用它，并且您应该至少有Guard插件工作:

   $ bundle exec guard -i

2. 查找最后一个可用的Pry版本

   我认为你应该让它在旧版本的Pry上运行，问题是哪个版本引入了不兼容性。您可以通过在Gemfile中指定版本并运行捆绑器来使用固定的Pry版本:

   在你的Gemfile:

   gem 'pry', '0.9.11.2'

   然后在控制台上运行bundler:

   $ bundle update

   如果它仍然不起作用，就使用低版本。请尝试0.9.11.2, 0.9.11.1, 0.9.11和0.9.10。

   如果你发现了一个可用的版本，请报告给GitHub链接的守卫问题。
