Eglot issues with python-lsp-server:

[zeta-00]

Greetings,

I'm having an issue where Eglot is not working with python-lsp-server, sometimes Eglot dies and throws the missing pkgs_resources error(I have setup tools install in macos, so I'm not sure what's wrong), and when I try:

(add-to-list 'eglot-server-programs '(python-mode . ("python-lsp-server"))),

Eglot is not able to find python-lsp-server binary PATH?

If you could give me some tips on how to fix this issue.

python-lsp/python-lsp-server#157

python3 -m pylsp --check-parent-process

Thanks in advance for the help.

Note I'm using an M1 mac(aarch64-darwin), and with Emacs I'm using use-package.

Also, I'm using the Nix package manager to handle the Python packages. The hash id of the Python packages changes because of this, so I'm wondering if there's a more generic way to declare the python-lsp-server binary PATH?

This link has some good documentation, but, it's specific to lsp-mode and Microsoft's python-language-server, so I'm not sure how to do something similar with Eglot and Nix.

As someone using eglot + python-lsp-server with nix and nix shells, I don't need to set eglot-server-programs at all - it just resolves the binary from $PATH by default.

Note that the binary for that project isn't called python-lsp-server, but pylsp. If you don't set eglot-server-programs, it should resolve that by default, assuming it actually is on your $PATH; your configuration overrides the default behavior and presumably breaks it because the binary name is now wrong.
