可以用768 MB的RAM安装yesod吗？

Question

我是haskell和yesod的新手。我按照quick start guide安装了yesod。

但是在第3步，当我运行stack install yesod-bin cabal-install --install-ghc命令时，CPU使用率变为100％，过了一段时间，它会引发错误：

~/my-project$ stack install yesod-bin cabal-install --install-ghc
Cabal-1.22.6.0: configure
Progress: 1/108
....
[19 of 79] Compiling Distribution.PackageDescription ( Distribution/PackageDescription.hs, /tmp/stack2919/Cabal-1.22.6.0/.stack-work/dist/x86_64-linux/Cabal-1.22.5.0/setup/Distribution/PackageDescription.o )
    ghc: out of memory (requested 2097152 bytes)

我还发现其他程序已被杀死（Node.js服务器）......

这是我的服务器信息：

但是，我在yesod的官方网站上找不到任何硬件。
