Well, a few moments ago, I was able to successfully run with:
stack install ghcide --compiler ghc-8.8.1
and stack.yaml:
extra-deps:
- haskell-lsp-0.17.0.0
- haskell-lsp-types-0.17.0.0
resolver: nightly-2019-12-06
even if stack was complaining about versions of ghc and cabal.
Thanks and regards
Dusan

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.
Cheers,

Does that mean the ghcide is broken? Or am I doing something wrong?
Taking a quick look at recent ghcide commits, I see:
https://github.com/digital-asset/ghcide/commit/e78e1638ea00af7c5bf4fdbae245413eafed4248
which shows changes to a stack.yaml file using "resolver: nightly-2019-12-06".
The removed extra-deps are:
- haskell-lsp-0.18.0.0
- lsp-test-0.8.2.0
- hslogger-1.3.0.0
- network-bsd-2.8.1.0
and the presumably expectation is that these will show up in a stack release soon.
But in the mean time you've selected:
- haskell-lsp-0.17.0.0
- haskell-lsp-types-0.17.0.0
- hie-bios-0.2.1
- rope-utf16-splay-0.3.1.0
which are older, and may not work with GHC 8.8.1 (MFP changes) used by recent
stack nightly builds. You could try changing the stack.yaml file to use an
even more recent nightly, but ultimately, may need to figure out the right
versions of the extra dependencies.
