我删除了一些文件，然后将它们重新添加到github，以便gitignore可以正常工作，然后通过capistrano将这些文件上传到服务器。
然后开始在precompile:assets上部署失败。
我能够找到问题，解决，现在cap env deploy:precompile:assets使我全都绿了。但是当我运行cap env deploy时，我仍然得到：

Tasks: TOP => deploy:assets:precompile
The deploy has failed with an error: Exception while executing as deploy@staging.myapp.com: Connection reset by peer - recvfrom(2)
** Invoke deploy:failed (first_time)
** Execute deploy:failed
** DEPLOY FAILED
由于任务似乎可以正常工作，因此不确定如何进行故障排除，而且我肯定可以连接到服务器（通过上限等方式上传文件...）
感谢任何提示
