Windows上的堆栈构建挂在GHC-8.6.4 / Cabal-2.4.1.0上

Question

我的堆栈项目构建在与Cabal有关的步骤中挂在Windows上。

见下面的输出

C:\haskell\hrt\Comonad>stack ghc -- --version
The Glorious Glasgow Haskell Compilation System, version 8.6.4

C:\haskell\hrt\Comonad>stack build
?[0mCabal-2.4.1.0: configure?[0m
?[0mCabal-2.4.1.0: build?[0m
Progress 0/5

我必须用Ctrl+ 打断C

我一直在尝试追踪Dmitrii Kovanikov撰写的Haskell Weekly Comonadic建筑商，并从创建一个新项目开始

stack new Comonad
cd Comonad

然后将代码示例粘贴到Main中

{-# LANGUAGE OverloadedStrings #-}
{-# LANGUAGE RecordWildCards   #-}

module Main where

import Control.Comonad (Comonad (..), (=>>))
import Data.Semigroup (Any (..))
import Data.Text (Text)
import Text.Pretty.Simple (pPrint)

import Lib
-- see the gist above for the rest of the code
alwaysTravisB :: ProjectBuilder -> Project
alwaysTravisB builder = builder $ mempty { settingsTravis = Any True }

travisB :: ProjectBuilder -> Project
travisB builder =
  let project = extract builder
  in project { projectTravis = projectGitHub project }



main :: IO ()
main = do
    -- plain
    pPrint $ extract $ buildProject "minimal-project"
    pPrint $ extract $ buildProject "only-library" =>> hasLibraryB
    pPrint $ extract $ buildProject "library-github" =>> hasLibraryB =>> gitHubB

    -- dependent: 1 level
    pPrint $ extract $ buildProject "travis" =>> travisB
    pPrint $ extract $ buildProject "always-travis" =>> alwaysTravisB
    pPrint $ extract $ buildProject "github-travis" =>> gitHubB =>> travisB
    pPrint $ extract $ buildProject "travis-github" =>> travisB =>> gitHubB
    someFunc

并且我在package.yaml中指定了依赖项

dependencies:
- base >= 4.12.0.0
- comonad >= 5.0
- pretty-simple >= 2.2
- text

library:
  source-dirs: src

executables:
  Comonad-exe:
    main:                Main.hs
    source-dirs:         app
    ghc-options:
    - -threaded
    - -rtsopts
    - -with-rtsopts=-N
    dependencies:
    - Comonad

我可以看到它ghc.exe正在临时文件夹（C:\Users\MyHome\AppData\Local\Temp\stacknnnn）上工作并使CPU保持忙碌，我也想知道这是否是内存泄漏（1.7GB的工作集）...

Answer 1

尝试使用运行--interleaved-output，将显示GHC正在编译的每个模块的输出（您可能需要先通过升级Stack stack upgrade）。Cabal需要很长时间才能编译，可能只是在所有模块中工作。
