Hi, I’m a new programmer of Elixir. I got a problem when using coc-elixir and elixir-ls.

While I can go to definition of all libs installed by mix, I can’t do that for modules implemented by Elixir. For example, I can go to modules of Ecto, Finch, Redix, but I can’t go to GenServer, Supervisor, Application, Keyword, Enum and Map.

Here is :gen_server.module_info. It’s strange that the source is ‘/buildroot/otp/lib/stdlib/src/gen_server.erl’, which I never have this path on my own computer.

I tried installing Elixir by homebrew or asdf. I also compiled an Elixir from the source code. The source has not changed.
