Question

我最近将我的应用程序升级到了GHC 8.4，并试图将其部署到生产环境中。不幸的是，当我尝试在持续集成服务器上编译该应用程序时，每次都会耗尽内存。（多年来，此应用程序一直在该相同服务上进行编译，而没有出现问题。）是否有任何方法可以配置GHC / Stack以使编译使用的资源更少？可以，这样会使编译速度变慢。

对于上下文，这是编译器崩溃的地方：

Progress 171/271: aeson-1.2.4.0                               aeson-1.2.4.0: copy/register
Progress 171/271: aeson-1.2.4.0                               Progress 172/271

--  While building custom Setup.hs for package Cabal-2.2.0.1 using:
      /root/.stack/setup-exe-cache/x86_64-linux/Cabal-simple_mPHDZzAJ_2.2.0.1_ghc-8.4.3 --builddir=.stack-work/dist/x86_64-linux/Cabal-2.2.0.1 build --ghc-options " -ddump-hi -ddump-to-file -fdiagnostics-color=always"
    Process exited with code: ExitFailure (-9) (THIS MAY INDICATE OUT OF MEMORY)

ETA：该问题已被标记为Cabal install criterion out of memory的重复项，但不幸的是，该解决方案无济于事。如果我将stack build更改为stack build --ghc-options '+RTS -M1500M -RTS'，那似乎只会使崩溃发生的时间更早：

Cabal-2.2.0.1: copy/register
Progress 171/271: Cabal-2.2.0.1                               Progress 172/271

使用GHC编译时内存不足
