This should work. Perhaps you have another extension that is conflicting? What other extensions do you have installed?

I’ve now updated that wiki to list ElixirLS before VSCode-Elixir, but I think it’s still a little bit early to call VSCode-Elixir unmaintained so I haven’t removed it.

It begins at 6:42.

It will be good to update this page:

And put just the Elixir LS which will continue and have updates, like tells on changelog:

v0.3.3: 15 Apr 2020

Meta:

• The original repository at JakeBecker/elixir-ls has now been deprecated in favor of elixir-lsp/elixir-ls. Any IDE extensions that use ElixirLS should switch to using this repository. The “ElixirLS Fork” extension on the VS Code marketplace will be deprecated, and updates will continue at the original ElixirLS extension
