【问题描述】：

我的资产在生产中预编译了将近 15 分钟，因此有时它会中止。

我的其他项目不需要这么长时间。看起来即使开始任务也需要很长时间。

以下是日志。

你解决过这个问题吗？

【解决方案1】：

我不确定您的问题的原因是什么，但我在尝试将应用程序部署到 Digital Ocean 时遇到了类似的问题，dropplet 的规格最低，因此 RAM 和共享内存非常小，导致中止预编译任务中的部署。我解决了增加共享内存和 RAM 大小的问题。

这些链接帮助我解决了问题，希望对你也有帮助。

增加内存：

Rake assets:precompile gets killed when there is a console session open in production

增加共享内存：
