I just started trying Elixir today and configuring the dev environment in vscode and got this error.

Here is some basic information below :

Erlang/OTP 24 [erts-12.2.1] [source] [64-bit] [smp:20:20] [ds:20:20:10] [async-threads:1] [jit]
Elixir 1.12.2 (compiled with Erlang/OTP 24)

I created a project following this tutorial https://elixir-lang.org/getting-started/mix-otp/introduction-to-mix.html

After installing this vscode plugin " ElixirLS: Elixir support and debuggerv0.14.5"

I got this error message.

could not compile dependency :sourceror, “mix compile” failed. You can recompile this dependency with “mix deps.compile sourceror”, update it with “mix deps.update sourceror” or clean it with “mix deps.clean sourceror”
[Error - 21:37:22] Server initialization failed.

[Info - 21:37:22] Connection to server got closed. Server will restart.
true
[Error - 21:37:22] ElixirLS - kv client: couldn’t create connection to server.
Message: Pending response rejected since connection got disposed
Code: -32097

I googled similar issues and no solution fixed my problem interestingly, there is no “.elixir_ls/” in the project root.
I think this must be a really trivial mistake and it took me 3 hours
