Does the add-on support the `rubyLsp.bundleGemfile` setting?

[zarembas]

I use the Ruby LSP extension with a separate Gemfile, not the one from the project. I'm unsure whether this works properly with the Rails add-on as I'm getting this error in the output.

Ruby LSP Rails failed to initialize server: /Users/seb/.local/share/mise/installs/ruby/3.3.7/lib/ruby/gems/3.3.0/gems/ruby-lsp-rails-0.4.6/lib/ruby_lsp/ruby_lsp_rails/runner_client.rb:121:in `rescue in initialize': /Users/seb/.local/share/mise/installs/ruby/3.3.7/lib/ruby/gems/3.3.0/gems/psych-5.2.6/lib/psych/visitors/to_ruby.rb:471:in `visit_Psych_Nodes_Alias': Alias parsing was not enabled. To enable it, pass `aliases: true` to `Psych::load` or `Psych::safe_load`. (Psych::AliasesNotEnabled) (RubyLsp::Rails::RunnerClient::InitializationError)

I'm guessing it has something to do with the Rails server not running from the same place.

When you say, "with a separate Gemfile," where is that Gemfile? What do your ruby LSP settings look like?

Hey, these are the settings:

    "rubyLsp.addonSettings": {},
    "rubyLsp.bundleGemfile": "/Users/seb/Code/ruby-lsp/Gemfile",
    "rubyLsp.enabledFeatures": {
        "codeActions": true,
        "codeLens": true,
        "completion": true,
        "definition": true,
        "diagnostics": true,
        "documentHighlights": true,
        "documentLink": true,
        "documentSymbols": true,
        "foldingRanges": true,
        "formatting": true,
        "hover": true,
        "inlayHint": true,
        "onTypeFormatting": true,
        "selectionRanges": true,
        "semanticHighlighting": true,
        "signatureHelp": true,
        "typeHierarchy": true,
        "workspaceSymbol": true
    },
    "rubyLsp.formatter": "rubocop",
    "rubyLsp.rubyVersionManager": {
        "identifier": "mise",
        "miseExecutablePath": "/opt/homebrew/bin/mise"
    },

I run it from the ruby-lsp folder, not the project's folder.

When using a custom bundle like in this scenario, the access of the Ruby LSP to project dependencies is limited, which is what I suspect might be happening here. The error is coming from parsing YAML files.

Some questions to better understand:

1. I assume you have manually added ruby-lsp-rails to that /ruby-lsp/Gemfile, correct?
2. If you manually boot runtime server, do you see the same error? Here are the steps to do it

• Figure out where ruby-lsp-rails is installed BUNDLE_GEMFILE=/Users/seb/Code/ruby-lsp/Gemfile bundle show ruby-lsp-rails
• Take the path you got in the previous step and then try launching the server manually

BUNDLE_GEMFILE=/Users/seb/Code/ruby-lsp/Gemfile bundle exec rails runner /path/to/ruby-lsp-rails/lib/ruby_lsp/server.rb start

@vinistock Thank you for your reply. By running the code you mentioned I realised what the issue was. I didn't have rails in my other Gemfile:

❯ BUNDLE_GEMFILE=/Users/seb/Code/ruby-lsp/Gemfile bundle exec rails runner  /Users/seb/.local/share/mise/installs/ruby/3.3.7/lib/ruby/gems/3.3.0/gems/ruby-lsp-rails-0.4.6/lib/ruby_lsp/server.rb start
bundler: failed to load command: rails (/Users/seb/.local/share/mise/installs/ruby/3.3.7/bin/rails)

It works fine now. Thank you for your help everyone.
