我的MacOS上安装了ghc 8.2.1。但是我的全局ghc-mod
仍在使用8.0.2,因为我最近将ghc升级到8.2.1。我想升级ghc-mod
。我尝试了以下命令,它返回错误如下:
▸ ghc --version
The Glorious Glasgow Haskell Compilation System, version 8.2.1
▸ ghc-mod --version
ghc-mod version 5.7.0.0 compiled by GHC 8.0.2
▸ stack build --copy-compiler-tool ghc-mod hoogle weeder
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)
cabal-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-1.6.2 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
monad-journal-0.8.1 from stack configuration does not match <0.8 && >=0.4 (latest matching version is 0.7.2)
optparse-applicative-0.14.0.0 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 potential ways to resolve this:
* Recommended action: try adding the following to your extra-deps in /Users/leo/zhangchiqing/hello/stack.yaml:
- Cabal-1.24.2.0
- base-4.9.1.0
- cabal-helper-0.7.3.0
- extra-1.5.3
- monad-journal-0.7.2
- optparse-applicative-0.13.2.0
* Set 'allow-newer: true' to ignore all version constraints and build anyway.
* You may also want to try using the 'stack solver' command.
