聲明變量Coffee.Script

Question

我是一個新的Hubot/Node.js/CoffeeScript用戶。

我正在查看Hubot的UptimeRobot腳本。當我包括在我的包，我發現了錯誤：

ERROR Error loading scripts from npm package - Error: Uptime Robot API Key must be provided 
    at Client (/home/myhubot/node_modules/uptime-robot/index.js:11:11) 
    at Robot.loadExternalScripts (/home/myhubot/node_modules/hubot/src/robot.coffee:263:11, <js>:212:39) 
    at /home/myhubot/node_modules/hubot/bin/hubot:119:11, <js>:123:26 
    at fs.js:268:14 
    at Object.oncomplete (fs.js:107:15) 

這裏是默認UptimeRobot.Coffee文件（位於在/ home/myhubot /腳本） http://pastebin.com/aeDgZu0B

例如，我已宣佈我的HUBOT_UPTIMEROBOT_APIKEY爲「11223344」

這是聲明全局變量的適當方式嗎？

     .get() (err, res, body) -> 
     response = JSON.parse(body) 

     if response.stat is "ok" 
      msg.send "done" 

     if response.stat is "fail" 
      msg.send "#{response.message}"

你有HUBOT_UPTIMEROBOT_APIKEY="11223344"，但你實際上並沒有使用它，因爲你也有apiKey = process.env.HUBOT_UPTIMEROBOT_APIKEY。這試圖把它從環境中拉出來。我假設你從來沒有設置任何環境變量，所以應該是未定義的。請參閱https://nodejs.org/api/process.html#process_process_env
