在部署期间，我得到以下输出：
[xx.xxx.xxx.xx] executing command
** [out :: xx.xxx.xxx.xx] ** Invoke assets:precompile (first_time)
** [out :: xx.xxx.xxx.xx] ** Execute assets:precompile

** [out :: xx.xxx.xxx.xx] ** Execute tmp:cache:clear
** [out :: xx.xxx.xxx.xx] ** Execute assets:precompile:primary
** [out :: xx.xxx.xxx.xx] Killed
bundle -v输出为1.1.5
我找到的解决方案是重启服务器并在之后立即部署。否则，我无法部署到生产环境，我不知道如何调试此问题，因为除了在部署时死亡之外没有其他输出。
