Remote development Ruby LSP doesn't start / wrong LSP is tried based on config

[tdegrunt]

Originally filed as zed-industries/zed#28753, but later I found this repo, so reopening here. Will close original issue.

Summary

Remote development Ruby LSP doesn't start / wrong LSP is tried, based on config
I'm connecting to a devcontainer / docker container, macOS host, Debian bookworm aarch64 container.

Description

• Install Ruby extension

Steps to reproduce:

1. Open a remote project and open a Ruby file

Expected Behavior:
I expect ruby-lsp to start, but it seems to want to start solargraph.

Actual Behavior:
ruby-lsp doesn't start, it's not visible in the servers list:

settings.json:

{
"languages": {
    "Ruby": {
      "language_servers": ["ruby-lsp", "rubocop", "!solargraph"]
    }
  },
  "lsp": {
    "ruby-lsp": {
      "initialization_options": {
        "formatter": "standard",
        "linters": ["standard"]
      },
      "settings": {
        "use_bundler": true
      }
    }
  }

ruby-lsp is installed and working:

vscode ➜ /workspaces/server (main) $ bundle exec ruby-lsp --version
0.23.13

In other issues I've read that installing libssl1.1 is what should fix this issue. I'm using Debian Bookwork, where libssl1 is deprecated and uses libssl3. Nonetheless I've tried with:

wget http://security.debian.org/debian-security/pool/updates/main/o/openssl/libssl1.1_1.1.1w-0+deb11u2_arm64.deb
sudo dpkg -i ./libssl1.1_1.1.1w-0+deb11u2_arm64.deb

Sadly that still doesn't start LSP's for me.

An update from me, currently using Ruby v0.7.3 and Zed 0.186.9.
I've added a .zed/settings.json to my project, the contents of that file is the following:

{
    "load_direnv": "shell_hook",
    "languages": {
        "Ruby": {
            "language_servers": ["ruby-lsp", "rubocop", "!solargraph"]
        }
    },
    "lsp": {
        "ruby-lsp": {
            "initialization_options": {
                "formatter": "standard",
                "linters": ["standard"]
            },
            "settings": {
                "use_bundler": true
            }
        }
    },
    "shell_hook": {
        "commands": ["direnv hook zsh"]
    }
}

Ruby LSP wouldn't initially start upon project open (and opening a Ruby file), but with the use of "editor: restart language server" all of a sudden I saw Ruby LSP starting.

I'm don't understand yet why it works now, it could be to load_direnv and that shell_hook, stuff I found online, as that's missing from my ~/.config/zed/settings.json.

I don't see any Ruby LSP logs, but I do see this:

Not yet ready to close this ticket as it seems very brittle (you always need to use "editor: restart language server")

[Update]
After restarting Zed I see this:

[Update 2]
Putting just this in global settings.json, doesn't work:

{
    "load_direnv": "shell_hook",
    "shell_hook": {
        "commands": ["direnv hook zsh"]
    }
}

Only the above really works, the sweet spot it seems?

I'm facing this same issue. I've copied your exact settings.json. ruby-lsp and standard are both installed and work with and without bundler. If I try "editor: restart language server", I get this in my logs:

2025-07-10T09:30:59-06:00 ERROR [project::lsp_store] (remote server) Failed to start language server "solargraph": "from extension \"Ruby\" version 0.12.0: No such file or directory (os error 2)"

[tdegrunt]

Only seeing this now, are you using the .zed/settings.json from here: #81 (comment) ?
I'm using zsh, you may not? Also I'm using direnv/rbenv. The only thing in my .envrc of note is:
export RBENV_VERSION=$(cat .ruby-version)

I haven't tried this with newer versions of zed yet.

[joshfester]

@tdegrunt I am using those same settings. I'm also using zsh. I use mise to manage my ruby installs, but I'm not sure if that could cause any issues here
