[Haskell-cafe] stack install ghcide fails

Well, a few moments ago, I was able to successfully run with:

stack install ghcide --compiler ghc-8.8.1

and stack.yaml:

  - haskell-lsp-
  - haskell-lsp-types-
resolver: nightly-2019-12-06

even if stack was complaining about versions of ghc and cabal.

Thanks and regards


Smells a bit like it only applies the MonadFail instance in ghc 8.8.1, but the build log 
said ghc 8.6 and implied MonadFailDesugaring enabled from the error message.

cabal install ghcide -w ghc-8.8.1 seems to work, so I don’t think it’s ghcide precisely.

Does that mean the ghcide is broken? Or am I doing something wrong?
