我正在尝试在一个干净的（新）VPS 服务器上堆叠构建一个新的基于 Yesod 的项目，该服务器在 Ubuntu Trusty x86_64 上运行。

如果它对问题很重要，这里是内存信息：

me@user:~/proj-web01$ free -h
            total       used       free     shared    buffers     cached
Mem:        1.0G         46M        977M     8.8M      0B          11M
-/+ buffers/cache:       35M        988M
Swap:          0B         0B          0B

这是堆栈项目的 cabal 文件的一部分：

library
  hs-source-dirs:      src
  exposed-modules:     Lib
  build-depends:       base >= 4.7 && < 5
  default-language:    Haskell2010

executable proj-web01-exe
  hs-source-dirs:      app
  main-is:             Main.hs
  ghc-options:         -threaded -rtsopts -with-rtsopts=-N
  build-depends:       base, yesod
                     , proj-web01
  default-language:    Haskell2010

除了 yesod 之外，依赖项中还有其他包，当我stack build没有在依赖项中添加 yesod 时，各种包正常下载并且一切看起来都很好 - 当然构建无法完成，因为还需要 yesod。

但是，当我添加 yesod 依赖项列表时，我收到一条Progress: 0/96Killed错误消息。依赖项列表中是否存在其他包似乎并不重要。这是一个转储stack build --verbose：

me@user:~/proj-web01$ stack build --verbose

Progress: 0/96Killed

我在这些输出消息中看不到任何东西，它提供了最后发生的事情的线索Progress: 0/96Killed，没有警告，什么都没有……我在网上搜索了类似的问题，但找不到任何问题，我被困在那里。

我的问题：我应该寻找什么，我还应该在哪里看？有没有我应该做的测试让我知道问题可能来自哪里？谢谢。

== 编辑 ==

事实上，这个问题更容易重现：

me@user:~/proj-web00$ stack install yesod
Progress: 0/95Killed
me@user:~/proj-web00$

安装其他较小的软件包就可以了（例如stack install csv...）

按照 Sibi 的建议，我尝试增加 VPS 上的交换空间，但显然这在用户级别是不允许的（U&L 讨论）。围绕这个限制有一些技巧，但是在尝试安装yesod时似乎并没有改变任何东西。

不是一个很好的技术解决方案，但我更改了 VPS 提供商，在相同的操作系统和相同的明显规格上运行，并且我可以轻松完成stack build所有事情（包括 yesod 套件）。

新的 VPS 服务提供商允许基于用户的交换，但我已经检查过这是没有必要的，并且我仍然可以在没有交换文件的情况下进行编译（但显然，它更慢）。
