问题 Stack allows global installation of packages using stack install <packagename> outside of a project directory. Stack also has a ~/.stack/global-project/stack.yaml file that allows configuration of the global-project. However I can't see a way to "install" packages declaratively. The extra-deps and packages key in the yaml file don't seem to work for this method. Instead I just have to run stack install <...> <...> each time the snapshot version gets updated for my global-project. 来源： https:/

问题 I'm building a Haskell 7.10 project that depends on tdsodbc.dll, using stack v1.7.1 on Windows, everything 64-bit. I have tdsodbc.dll in the lib folder of the project, and extra-lib-dirs: lib and extra-libraries: tdsodbc in the .cabal. But when I compile, I get Missing C library: tdsodbc when stack runs cabal configure . I've tried putting extra-lib-dirs: [lib] in stack.yaml , and I can see from that configure command that it has put --extra-lib-dirs=C:\Users\Kevin\src\theproject\lib on the

问题 Using stack 1.2.0 and LTS 7.0 I'm getting the following error installing the shuffle library: $ cabal get shuffle $ cd shuffle-0.1.3.3 $ stack build ... /tmp/shuffle-0.1.3.3/Setup.hs:2:1: error: Failed to load interface for ‘Distribution.Simple.UUAGC’ Perhaps you meant Distribution.Simple.UHC (from Cabal-1.24.0.0) Distribution.Simple.GHC (from Cabal-1.24.0.0) Distribution.Simple.JHC (from Cabal-1.24.0.0) Use -v to see a list of the files searched for. /tmp/shuffle-0.1.3.3/Setup.hs:3:1: error:

问题 I'm writing a project using Haskell, stack and hint . I'm using hint to interpret a user-supplied module. The catch is that this module uses types and functions from a dependency. When I run my program using stack exec , everything works fine. However, when I install my program (using stack install --local-bin-path bin ) and try to run the executable generated, the GHC interpreter fails with an error: Could not find module <module> . This is because (I think) it can't find the files needed

问题 Building project dependent on glib fails on lts-7.8 and later after Cabal becomes 1.24.1.0. Steps to reproduce Add glib to a project's .cabal file build-depends: base , gtktest , glib Run following commands stack install gtk2hs-buildtools stack build Result The following error occurred ... [debug] Ignoring package Cabal due to wanting version 1.24.1.0 instead of 1.24.0.0 @(Stack\Build\Installed.hs:196:5) ... -- While building package glib-0.13.4.1 using: C:\Users\foo\AppData\Local\Programs

问题 I'm trying to follow the tutorial for the Beam Haskell library: https://tathougies.github.io/beam/tutorials/tutorial1/ module Lib ( someFunc ) where {-# LANGUAGE DeriveGeneric , GADTs , OverloadedStrings , FlexibleContexts , FlexibleInstances , TypeFamilies , TypeApplications #-} import Database.Beam import Database.Beam.Postgres import GHC.Generics import Data.Text (Text) data UserT f = User { _userEmail :: Columnar f Text , _userFirstName :: Columnar f Text , _userLastName :: Columnar f

问题 I'm using the following .gitlab-ci.yml file for setting up gitlab-CI for a Haskell Stack project created with stack new actividad3 --resolver=lts-14.6 . image: haskell:8.6.5 cache: paths: - .stack - .stack-work - target test: stage: test script: - ghc --version - stack --system-ghc build - stack test Building and testing the project last almost 5 minutes. Most of the time is spent building the hspec library. Is there any way to cache the used libraries between pipeline runs? Thanks in advance

问题 I'm trying to use the req package (http://hackage.haskell.org/package/req) in a Haskell project, with stack. So far, I've done stack new my-project , stack setup , stack build and stack exec my-project-exe all fine. Have added req to the cabal file like so: name: my-project version: 0.1.0.0 synopsis: Short description of your package homepage: https://github.com/githubuser/#readme license: BSD3 license-file: LICENSE author: Author name here maintainer: example@example.com copyright: 2017

问题 I have GHC installed through stack ( so that stack ghc -- --version shows GHC-7.10.3 ) $ stack install ghcjs Run from outside a project, using implicit global project config Using resolver: lts-5.2 from implicit global project's config file: /home/john/.stack/global-project/stack.yaml The following target packages were not found: ghcjs Some resources suggest ghcjs is somewhat experimental (though in the further stages). Looking at http://docs.haskellstack.org/en/stable/ghcjs/ I thought maybe
