Curious error with 'bundler/inline': Failed loading plugin `standard-custom' because we couldn't determine (RuntimeError) the corresponding plugin class to instantiate. #591

Okay, I'll be honest, this one sucks. First, I was able to reproduce this repeatedly by uninstalling standard-custom before each run (and nuking the local bundle folder): #!/usr/bin/env ruby
system "gem uninstall --ignore-dependencies --force standard-custom"
require 'bundler/inline'
gemfile(true) do
source "https://rubygems.org"
gem 'standard', path: '../standard'
end
load Gem.bin_path("standard", "standardrb")Given that the class raising this error also does some clever stuff when requiring each plugin, I expected that this line would be the culprit, which in this situation resolves to The issue appears to be at the line raising the error: Kernel.const_get(Gem.loaded_specs[plugin_name].metadata["default_lint_roller_plugin"])Where Gem::Specification.new do |s|

I think that should be our next step. Paging @deivid-rodriguez and @hsbt in case they might be able to offer advice here |
I'm trying to create a self-contained script to run
standardusingbundler/inlinelike this:Whenever I call this script and
standard-customis not already installed, it raises the strange error from this issue's title. If I re-run the script it works as expected. If I removestandard-customfrom./.bundleand re-run the script, the error occurs again.If I use a standalone
Gemfile, the error does not occur, even if installing gems and running the code happens in one process.Details:
This is on MacOS 14.1. ("Sonoma"), in case that matters.
I'd love to spare myself a
Gemfile, so I'd be happy for any ideas or fixes.If I can help with further information, please let me know.
