【问题描述】：

我刚开始探索粉碎（以前称为 dashing）。

基于此处的网址，https://github.com/Shopify/dashing/wiki/Dashing-Workshop

我要做的只是从本地文件中简单地读取。

本地文件位于其他目录，名称为googlestatus，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

但是当我运行粉碎启动时，它给了我以下错误：

Arrived

【解决方案1】：

您的代码有几个问题：

您需要在代码中将文件名放在引号中，即：
```
puts File.read("./status/googlestatus")
```
现在，您（尝试）在启动期间仅读取文件内容一次。然后，它的一次读取值将每秒钟发送一次，而不再被读取。您可能希望将文件的读取放入计划的块中。
最后，您尝试读取的文件似乎在启动期间不存在（尚不存在）。
