计划作业错误的帮助 - Rails的亚军错误

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几点：

1. Load Ruby with RVM
2. 导航到MyApp迪尔
3. 运行以下行：rails runner "Resque.enqueue(Place)

以上cron似乎正在运行，但它与产生以下错误 怎么回事？

Answer 1

其实要做到这一点是使用RVM包装的最佳方式。你可以创建一个这样的包装：

rvm wrapper ruby-1.9.3-p0@somegemset appname rails 

二进制文件可以是rails，rake，gem或其他你已经安装的ruby二进制文件。会发生什么是rvm创建一个包装器，它会在执行rails命令之前获取正确的rvm环境。在全系统RVM，包装通常会被放置在/ usr /本地/ RVM /斌/

现在从cron你可以这样做：

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

这将CD插入您的应用程序目录，执行你每3分钟创建一个rvm包装器。这个例子基于rails 3和生产环境。

很多搬到这里来块，这里有一对夫妇的事情指针在您的环境（红宝石，RVM，包）检查 - 发表您的调查结果，并会从那里。

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

Bundle bug

我猜命令运行的cron的罚款之外？如果您以不同的用户身份运行您的cron作业，请检查该用户的环境。

您需要在任何Ruby代码运行之前通过RVM通过正确的环境获取源代码。所以在命令中包括是这样的：

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

所以一个潜在的解决方案是：

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