I met a problem when I use the :LspInstall pyright, shown below.

[START][2024-01-08 21:43:41] LSP logging initiated
[WARN][2024-01-08 21:43:41] .../lua/vim/lsp.lua:101	"method textDocument/signatureHelp is not supported by any of the servers registered for the current buffer"

I use this because I havn't the auto completetion...
seems that any :LspInstall cannot work.

please help!
