計劃作業錯誤的幫助 - Rails的亞軍錯誤

Question

* * * * * /bin/bash -l -c 'cd /Users/boris/projects/MyApp/ && rails runner "Resque.enqueue(Place)"' 

基本上我需要做到以下幾點：

1. Load Ruby with RVM
2. 導航到MyApp迪爾
3. 運行以下行：rails runner "Resque.enqueue(Place)

以上cron似乎正在運行，但它與產生以下錯誤 怎麼回事？

其實要做到這一點是使用RVM包裝的最佳方式。你可以創建一個這樣的包裝：

rvm wrapper ruby-1.9.3-p0@somegemset appname rails 

二進制文件可以是rails，rake，gem或其他你已經安裝的ruby二進制文件。會發生什麼是rvm創建一個包裝器，它會在執行rails命令之前獲取正確的rvm環境。在全系統RVM，包裝通常會被放置在/ usr /本地/ RVM /斌/

現在從cron你可以這樣做：

*/3 * * * * cd /path/to/your/app && appname_rails runner "Resque.enqueue(Place)" -e production 

這將CD插入您的應用程序目錄，執行你每3分鐘創建一個rvm包裝器。這個例子基於rails 3和生產環境。

很多搬到這裏來塊，這裏有一對夫婦的事情指針在您的環境（紅寶石，RVM，包）檢查 - 發表您的調查結果，並會從那裏。

Path's issue with bundler, to change or not to change?

Bundle bug

我猜命令運行的cron的罰款之外？如果您以不同的用戶身份運行您的cron作業，請檢查該用戶的環境。

Answer 3

您需要在任何Ruby代碼運行之前通過RVM通過正確的環境獲取源代碼。所以在命令中包括是這樣的：

source /usr/local/rvm/environments/ruby-1.9.2-p180@my-gemset 

所以一個潛在的解決方案是：

SHELL=/bin/bash 
* * * * * source /{path_to_rvm_environment_for_ruby}@{gemset} && cd /Users/boris/projects/MyApp/ && rails runner "Resque.enqueue(Place)"'
