`堆栈构建`与Yesod的问题

我正在尝试在干净的（新的）VPS服务器上构建一个基于Yesod的新项目，该服务器在Ubuntu Trusty x86_64上运行。

如果问题很重要，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 - 当然除了构建无法完成，因为yesod也是需要。

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。如果依赖项列表中存在其他包，则似乎并不重要。这是stack build --verbose的转储：

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

Progress: 0/96Killed

我在这些输出消息中看不到任何内容，这些消息提供了最后发生的事情的线索Progress: 0/96Killed，没有任何警告，没有......我在网上搜索了类似的问题，但找不到任何问题，而且我我坚持了。

我的问题：我应该寻找什么，我还应该注意什么？我应该做一个测试，让我知道问题可能来自哪里？谢谢。

==编辑==

事实上，重现这个问题要简单得多：

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

安装其他较小的包可以正常工作（例如stack install csv ...）

根据Sibi的建议，我尝试增加VPS上的交换空间，但显然在用户级别（U&L discussion）不允许这样做。围绕此限制有hacks，但在尝试安装yesod时似乎没有任何改变。

1 个答案:

答案 0 :(得分：1)

这不是一个很好的技术解决方案，但我更改了VPS提供程序，运行相同的操作系统和相同的明显规格，我很容易stack build所有内容（包括yesod套件）。

新的VPS服务提供商允许用户基础交换，但我已经检查过它没有必要，我仍然可以在没有交换文件的情况下进行编译（但显然，它的速度较慢）。
