hls cannot work #94

Closed dwuggh closed 3 years ago

dwuggh commented 3 years ago

I created a new stack project test, change the resolver to ghc-8.10.1, and open app/Main.hs with emacs.

it seems hls can be started, but all capabilities failed to work.

Here's some info. from *lsp-haskell-stderr*:

If you are seeing this in a terminal, you probably should have run ghcide WITHOUT the --lsp option!

BTW, everything works fine before I updated these packages.

Are you sure you're on the latest lsp-mode? At any rate, this is a type error from inside lsp-mode, so you'll have better luck opening the issue there.
