Failed to start parse server

[wengzilla]

Currently using VSCode Prettier Plugin v10.4.0 + @prettier/plugin-ruby 4.0.2 + prettier 3.0.3.

I'm getting the following error:

Error: Failed to start parse server.
    at Timeout.<anonymous> (file:///.../node_modules/@prettier/plugin-ruby/src/plugin.js:127:16)
    at listOnTimeout (node:internal/timers:573:17)
    at process.processTimers (node:internal/timers:514:7)

However, if I run ./node_modules/.bin/prettier --plugin=@prettier/plugin-ruby --write '**/*' it works no problem. What's going on?

Same with @prettier/plugin-ruby 4.0.4 + prettier 3.3.3

Same error for me in WSL with @prettier/plugin-ruby 4.0.4 + prettier 3.4.0.

Did a little debugging and noticed that it's failing after 'require "syntax_tree"'. So I just tried to execute "bundle add" instead of "gem install" like this: "bundle add prettier_print syntax_tree syntax_tree-haml syntax_tree-rbs" and now it's working. I'm thinking it's because I'm using rbenv but not sure.

UPD: if I delete Gemfile it's starting to work

Downgrading to 4.0.2 also helps

The issue is resolved after deleting the following line of code:

plugin-ruby/src/plugin.js

Line 79 in ed8a257

options.cwd = path.dirname(prettierConfig);

Introducing an option to disable changing the child process's current working directory could provide a straightforward workaround.

I was hitting this, but updating the editor (VSCode/Cursor) seems to have resolved it for me.

I got:

OK, after gem install syntax_tree, it's working as expected now.
