cabal: Could not resolve dependencies:
trying: ghc-mod-5.8.0.0 (user goal)
next goal: base (dependency of ghc-mod-5.8.0.0)
rejecting: base-4.10.0.0/installed-4.1... (conflict: ghc-mod => base<4.10 && >=4.6.0.1)
rejecting: base-4.10.0.0, base-4.9.1.0, base-4.9.0.0, base-4.8.2.0,
base-4.8.1.0, base-4.8.0.0, base-4.7.0.2, base-4.7.0.1, base-4.7.0.0,
base-4.6.0.1, base-4.6.0.0, base-4.5.1.0, base-4.5.0.0, base-4.4.1.0,

base-4.2.0.0, base-4.1.0.0, base-4.0.0.0, base-3.0.3.2, base-3.0.3.1
(constraint from non-upgradeable package requires installed instance)
After searching the rest of the dependency tree exhaustively, these were the goals I've had most trouble fulfilling: base, ghc-mod, syb
发生了什么？还有，我该怎么办？
最佳答案
根据this ticket对于 ghc-mod，
GHC 8.2.1 is not supported yet, hence the base<4.10 constraint.
(截至 2917 年 9 月中旬)并且，
对 8.2.1 的功能支持已添加到 v5.9.0.0 milestone .
