Question

我刚刚开始研究粉碎（以前称为破折号）。

根据此处的网址https://github.com/Shopify/dashing/wiki/Dashing-Workshop

我想做的只是从本地文件中简单读取。

本地文件位于其他目录（名为googlestatus）中，并且包含：

connected

jobs / ops.orb包含：

gstatus = puts File.read(./status/googlestatus)

############ scheduler
SCHEDULER.every '1s', :first_in => 0 do |job|
  send_event('response_time', { value: gstatus })
end

但是当我运行smashing start时，它给了我以下错误：

您的代码有些错误：

您需要在文件的代码中用引号将文件名括起来，即：
```
puts File.read("./status/googlestatus")
```
现在，您（尝试）在启动过程中仅读取文件内容一次。然后，它一次读取的值将每秒钟发送一次，而无需再次读取。您可能希望将文件的读取放入计划的块中。
最后，似乎您尝试读取的文件在启动过程中还不存在。

错误读取文件-ENOENT：此类文件或目录@ rb_sysopen
