Have you configured as described here? https://shopify.github.io/ruby-lsp/version-managers.html#custom-activation

[paulschreiber]

I edited settings.json like so:

  "rubyLsp.rubyExecutablePath": "/opt/homebrew/opt/ruby/bin/ruby",
  "rubyLsp.customRubyCommand": "PATH=/opt/homebrew/opt/ruby/bin:$PATH",
  "rubyLsp.addonSettings": {},
  "rubyLsp.rubyVersionManager": {
    "identifier": "custom"
  }

Same error.

Also: one of my machines uses rbenv and this one does not. Is there a way to have both of them work if the VS Code settings are synced?

I think VS Code has some configuration for which settings are synced or not: https://code.visualstudio.com/docs/editor/settings-sync#_configuring-synced-data

Same error

Could you please share the server logs for the error you're getting now? Make sure to quit and re-open VS Code if you haven't already. (I bet you have, just making sure to check the obvious boxes before digging deeper)

@egiurleo Anything else I can gather that will help debug this?

[vinistock]

I edited settings.json like so:

You should not have any of those settings if you're using rbenv. All you need is:

{
  "rubyLsp.rubyVersionManager": {
    "identifier": "rbenv"
  }
}

If it still doesn't work after cleaning these up, then I don't believe it's an issue with our rbenv integration, but some customization that is layered on top of it. Do you have any Bundler or RubyGems settings?

The error from the output tab mentions not being able to find the global installation for the ruby-lsp gem in order to launch the server. Do you have any customizations as to where gem install places the installed gems? For example, something like --user-install.

[paulschreiber]

This works fine with rbenv. The errors occur on the machine without rbenv.

[vinistock]

Oh, okay. Sorry, I misunderstood. If you keep the rubyLsp.rubyExecutablePath, remove the rest and then set the version manager identifier to none, does that work?

If not, the question about Bundler or RubyGems customization still stands. Where are the gems installed for that Homebrew installation?

[paulschreiber]

I adjusted the settings like so:

  "rubyLsp.rubyVersionManager": {
    "identifier": "none"
  },
  "rubyLsp.rubyExecutablePath": "/opt/homebrew/opt/ruby/bin/ruby"
