Unable to start Elm Language Server

Thank you for creating this plugin, I’m excited to try it out.

I’ve installed the plugin, but I can’t figure out how to get it to start. I’ve tried it natively on Windows and using my Windows VS Code installation to SSH into a Linux server using the Remote-SSH tools.

Natively in Windows, I get this output for elmLS:

When I’m using a VS Code to SSH into Linux, I get this output:

If I can provide any additional information, please let me know.

Probably due to your node switch

I followed the directions on the README to build the language server, uninstalled the plugin and reinstalled it and now it’s working in Windows.

Thanks for your help!
