Troubleshooting

Server fails to start

Upon upgrading coc-elixir it is possible that the binary files were compiled using an OTP or Elixir version that differ from the ones you have installed. When this happens, the language server will fail to start.

You can build ElixirLS yourself to solve this:

Start by building a binary of ElixirLS from its source:

git clone https://github.com/elixir-lsp/elixir-ls.git ~/.elixir-ls
cd ~/.elixir-ls
mix deps.get && mix compile && mix elixir_ls.release -o release

Afterwards, create or update your coc-settings file and add this line:

{
  "elixir.pathToElixirLS": "~/.elixir-ls/release/language_server.sh"
}

To open your coc-settings file directly from Vim or Nvim, you can use this command:

:CocConfig

Doing these steps should make this plugin work with CoC.
