fresh install doesn't work

[ConnorRigby]

Precheck

• Do a quick search and make sure the issue has not yet been reported
• Do not use the issues tracker for guidance, questions or support (try Elixir Forum, Stack Overflow, Slack, etc. instead)
• If using a client other than VS Code, please try VSCode's "ElixirLS: Elixir support and debugger" extension. Does it reproduce your failure?

Environment

• Elixir & Erlang 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 1.15.0 (compiled with Erlang/OTP 26)

• Elixir Language Server version: v0.15.0
• Operating system: linux 6.3.8
• Editor or IDE name (e.g. Emacs/VSCode): VSCode
• Editor Plugin/LSP Client name and version:

Current behavior

setup a brand new machine. Installed Elixir and Erlang via asdf. Installed a fresh instance of VSCode, no settings sync or anything. Brand new install. No other extensions. Just ElixirLS.

ElixirLS logs. If using Visual Studio Code, check the output log by opening View > Output and selecting "ElixirLS" in the dropdown. Please include any output that looks relevant. (If ElixirLS isn't in the dropdown, the server failed to launch.)

no logs

If relevant include VSCode extension logs. Check the developer console by opening Help > Toggle Developer Tools.

no logs

If relevant include Language Server Protocol/Debug Adapter Protocol messages trace. In VSCode turn on tracing in Settings > Extensions > ElixirLS > Elixir LS › Trace: Server.

no logs

reproduction:

install the extension on a fresh linux + code install

Expected behavior

the extension should work

i've debugged a bit further, if i run code . in the project i want to use, it works. I'm not sure where the extension is getting it's environment from, but it fails in a different way. I get this message

I believe this is an issue with OTP 26. You'll need to use OTP 25 for the time-being. I ran into the same thing. #886 is tracking it.

Please refer to compatibility matrix. OTP 26 is not supported
