I'm trying to get this working with a new version of lsp-mode (20181217.630, using the new lsp-register-client functionality) and it is failing to run lsp-python-enable with the title error. I'm on Spacemacs v0.200.13, emacs 26.1.

I've tried running in debug mode with only the lsp-mode and lsp-python-ms packages (none of the spacemacs config included), and if I go to a python file and manually start lsp, the mspyls buffer is created but the server doesn't start because the executable command seems to be malformed. The exact error is: No executable found matching command "dotnet-Microsoft.Python.LanguageServer.dll"

The relevant section of my config looks like so:

(use-package lsp-mode :ensure t :config (require 'lsp-clients) ;; change nil to 't to enable logging of packets between emacs and the LS ;; this was invaluable for debugging communication with the MS Python Language Server ;; and comparing this with what vs.code is doing (setq lsp-print-io t)) (use-package lsp-python-ms :ensure nil :hook (python-mode . 'lsp-python-enable) :config ;; for dev build of language server (setq lsp-python-ms-dir (expand-file-name "/usr/local/etc/python-language-server/output/bin/Release/")))

Also full disclosure: In my attempts to debug and play around with different versions of lsp-mode I have further broken things, and now I'm getting the following error: lsp-python-ms.elc failed to define function lsp-python-enable. So I'll try to keep looking into this and provide any other info that might help, but also I'm going to try to fix the problems that I created 😅
