Make Ruby LSP work even old ruby projects.

Outside your main project, create a folder with these two files:

• .ruby-version with a version >= 3.0.0

3.0.0

• Gemfile

# frozen_string_literal: true

source 'https://rubygems.org'

gem 'ruby-lsp'
gem 'ruby-lsp-rails'

• In your Ruby project, create a VSCode settings file (e.g. .vscode/settings.json)

{
  "rubyLsp.bundleGemfile": "../path/to/above/Gemfile", // or absolute path
  "rubyLsp.rubyVersionManager": "rbenv",
}

• Install Ruby LSP plugin and restart VSCode.
