[英]Can not install GHC-Mod
大家好,我正在嘗試為 vscode 安裝 ghc-mod,但我遇到了這個問題:
**$ stack install ghc-mod**
Populated index cache.
Error: While constructing the build plan, the following exceptions were encountered:
In the dependencies for ghc-mod-5.8.0.0:
Cabal-2.0.1.1 from stack configuration does not match >=1.18 && <1.25 (latest matching version
is 1.24.2.0)
base-4.10.1.0 from stack configuration does not match >=4.6.0.1 && <4.10 (latest matching
version is 4.9.1.0)
mcabal-helper must match <0.8 && >=0.7.3.0, but the stack configuration has no specified version
(latest matching version is 0.7.3.0)
extra-1.6.8 from stack configuration does not match <1.6 && >=1.4 (latest matching version
is 1.5.3)
ghc-8.2.2 from stack configuration does not match >=7.6 && <8.2
haskell-src-exts-1.20.2 from stack configuration does not match <1.20 && >=1.18 (latest
matching version is 1.19.1)
hlint-2.1.6 from stack configuration does not match <2.1 && >=2.0.8 (latest matching version
is 2.0.15)
monad-journal-0.8.1 from stack configuration does not match <0.8 && >=0.4 (latest matching
version is 0.7.2)
optparse-applicative-0.14.2.0 from stack configuration does not match >=0.13.0.0 && <0.14
(latest matching version is 0.13.2.0)
needed since ghc-mod is a build target.
Some different approaches to resolving this:
* Consider trying 'stack solver', which uses the cabal-install solver to attempt to find some
working build configuration. This can be convenient when dealing with many complicated
constraint errors, but results may be unpredictable.
* Recommended action: try adding the following to your extra-deps
in C:\sr\global-project\stack.yaml:
- Cabal-1.24.2.0
- base-4.9.1.0
- cabal-helper-0.7.3.0
- extra-1.5.3
- haskell-src-exts-1.19.1
- hlint-2.0.15
- monad-journal-0.7.2
- optparse-applicative-0.13.2.0
Plan construction failed.
我試過stack install ghc-mod
和cabal install ghc-mod
都無濟於事。我總是讓這個plan construction failed
。關於如何處理它的任何想法?
PS :我已經更新了堆棧和陰謀集團。
在遵循用戶的建議后,我將文件添加到C:\\sr\\global-project/stack.yaml
,現在它看起來像這樣:
全局stack.yaml
:
packages: []
resolver: lts-11.13
Cabal-1.24.2.0
base-4.9.1.0
cabal-helper-0.7.3.0
extra-1.5.3
haskell-src-exts-1.19.1
hlint-2.0.15
monad-journal-0.7.2
optparse-applicative-0.13.2.0
添加所有這些文件后,我在運行stack install ghc-mod
時收到以下錯誤:
$ stack install ghc-mod

問題是ghc-mod
在 ghc-8.2 上不起作用。 支持ghc-mod
的最新 Stack 解析器似乎是lts-9.21
。
ghc-mod
必須使用您正在使用的相同版本的 GHC 進行編譯,因此現在將您限制在 8.0.0.0 上。
編輯(2020 年 8 月):ghc-mod 已被棄用,取而代之的是Haskell IDE 引擎(HIE)。
大多數使用最新工具鏈的人顯然沒有使用 ghc-mod,否則這會起作用。 也考慮放棄。
