Issue with lsp

[brrgrl]

Describe the bug When I try to run lsp on a file, I get the following message "lsp-execute-command is already defined as something else than a generic function"

and lsp doesn't start.

To Reproduce Steps to reproduce the behavior:

1. Open emacs
2. Visit a python file
3. lsp-mode doesn't active so try M-x lsp
4. See error

Expected behavior Should automagically start lsp-mode in buffer

Screenshots

Versions (please complete the following information):

• MacOS Sonoma 14.1.1
• GNU Emacs 29.1 (build 2, x86_64-apple-darwin23.1.0, NS appkit-2487.20 Version 14.1.1 (Build 23B81)) of 2023-11-29

Additional context I am able to get the expected behavior when I delete lsp and lsp-ui (along with its dependencies) and then reinstall via melpa. However, on startup, I return to the same error above.

Nevermind, I saw that it's due to not following the prerequisite for ccls

Feel free to try the experimental branch that uses lsp-bridge and tree-sitter :)
