elixir(1.8.1) 和 erlang(21.3.5) 是通过 .tool-versions(ASDF) 文件在本地设置的。

ElixirLS 使用上述版本的 elixir 启动，但需要更高版本。

我可以进行扩展以使用 elixir 的全球版本（由 ASDF 设置）吗？

在运行任何需要 Elixir 的东西（例如，在您的情况下为 VScode 和 ElixirLS）之前，您可以通过设置临时 shell 版本来覆盖 elixir 版本 - asdf shell elixir <elixir version you want>。这将设置 asdf shim 在运行时读取的 shell 环境变量，该变量将覆盖在.tool-versions. 当然，您需要在系统上安装您想要使用的 Elixir 版本，并从设置了环境变量的 shell 启动所有内容。

或者，您可以尝试这样的事情来.tool-versions完全禁用文件读取 - https://github.com/asdf-vm/asdf/issues/870#issuecomment-780862765
