我正在尝试使用cabal-debian
在全球安装软件包cabal v2-install cabal-debian
并收到以下错误消息:
Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: base-4.12.0.0/installed-4.1... (user goal)
[__1] trying: binary-0.8.7.0 (user goal)
[__2] next goal: ghc (user goal)
[__2] rejecting: ghc-8.6.5/installed-8.6... (conflict: binary==0.8.7.0,ghc =>
binary==0.8.6.0/installed-0.8...)
[__2] trying: ghc-8.6.5
[__3] rejecting: ghc:-buildable (conflict: base==4.12.0.0/installed-4.1...,ghc -buildable => base<0)
[__3] rejecting: ghc:+buildable (manual flag can only be changed explicitly)
[__3] fail (backjumping,conflict set: base,ghc,ghc:buildable)
After searching the rest of the dependency tree exhaustively,these were the
goals I've had most trouble fulfilling: binary,base,ghc:buildable
Try running with --minimize-conflict-set to improve the error message.
我正在使用cabal 3.0.0.0
,并已安装ghc 8.6.5
。
