Scala Can'；由于内存不足，无法在ec2上运行sbt（无法分配新内存）

由于某些原因，我无法在amazon ec2免费层运行sbt

ubuntu@ip-xx-xx-xx-xx:~$ sbt seed
Loading /usr/share/sbt/bin/sbt-launch-lib.bash

注意

sbt seed

在我的本地机器上工作（

“seed”

是我的自定义任务）

---

微实例的物理内存总量为613MB。如果需要更多，您可以启用交换，但请记住，这样会慢得多。

如何？我可以启用它只是为了让“sbt种子”运行，然后再次禁用它吗？@Alex否，您可以启用交换，使其始终处于活动状态。它会占用你的一些磁盘空间。为什么？默认情况下，它将在重新启动后被禁用。您是否尝试减小sbt使用的堆大小？如何执行此操作取决于启动程序脚本。
