File mode specification error: (void-function -compose) #114

Closed jwaldmann closed 3 years ago

jwaldmann commented 3 years ago

Hi. I am trying to use lsp-haskell. I have a built haskell-language-server(-wrapper), I have configured emacs. When loading a hs source file (in the top directory of a stack project with hie.yaml), emacs says

File mode specification error: (void-function -compose)

I found https://emacs.stackexchange.com/questions/63621/how-do-i-solve-lisp-error-void-function-compose-when-using-lsp-dart but I'm not sure what to make of it. package-install does not show a dart package (but several dart-*).

When I say M-x lsp-mode, I get (Haskell LSP[Disconnected] ...) in the mode line. (Is this a separate error?)

See https://github.com/emacs-lsp/lsp-mode/issues/2615.

Make sure you update package dash to the latest version.
