Hi, I am trying to get ElixerLS setup in VSCode but getting an error.

This is what I get in the Output tab:

[Info  - 10:14:54 AM] Started ElixirLS v0.13.0
[Info  - 10:14:54 AM] ElixirLS built with elixir "1.12.3" on OTP "22"

Environment

I am running code . from a WSL2 environment.

I used ASDF to install Elixir and Erlang, and I’m using the latest versions.

$ elixir --version
Erlang/OTP 26 [erts-14.0] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit:ns]

Elixir 1.14.4 (compiled with Erlang/OTP 26)

Basic troubleshooting steps

I have tried following the Troubleshooting steps in the readme…

  • Restart ElixirLS with a custom command restart

I ran Elixir: Restart Language Server and got an error messagebox:

Command 'Elixir: Restart language server' resulted in an error (Cannot read properties of undefined (reading 'capabilities'))
  • Run mix clean or mix clean --deps in ElixirLS with custom command mixClean

I ran Elixir: Trigger mix clean --deps in language server and got an error messagebox:

Command 'Elixir: Trigger mix clean --deps in language server' resulted in an error (Cannot read properties of undefined (reading 'capabilities'))
  • Restart your editor (which will restart ElixirLS)

This had no effect.

  • After stopping your editor, remove the entire .elixir_ls directory, then restart your editor

I have no .elixir_ls directory

I am running into the same problem.

I’m on a Mac M1 MBP.

elixir --version reports:

Erlang/OTP 26 [erts-14.0] [source] [64-bit] [smp:10:10] [ds:10:10:10] [async-threads:1] [jit]

I also run into the same problem in my new MBP M2. It might has to do with Erlang/OTP 26 or asdf itself.

The workaround was to install Erlang and Elixir via Homebrew where I noticed that it installed the latest version of Erlang/OTP 25 (not 26).

Rolling back to OTP 25 worked for me as well.

The same problem. OTP 25.3.2 with elixir 1.14.4 is working excellent, OTP 26.0 with elixir 1.14.5 generate errors: “ElixirLS - sgf-parsing client: couldn’t create connection to server.”
