Can't execute v1.34.0 with error "cannot load such file -- rubocop-rails"

[hiro-teaaa]

I can't run rubocop v1.34.0.
Downgrading to v1.33.0, I could run it correctly.

---

Expected behavior

In the rails project,

• execute % rubocop
• then execute correctly　

Actual behavior

% rubocop --debug
For /path-to/ruby-project: configuration from /path-to/ruby-project/.rubocop.yml
cannot load such file -- rubocop-rails

Steps to reproduce the problem

• Just do %rubocop

RuboCop version

% bundle exec rubocop -V
1.34.0 (using Parser 3.1.2.1, rubocop-ast 1.21.0, running on ruby 3.1.1 arm64-darwin21)
  - rubocop-rails 2.15.2

[unused]

Can confirm this issue. It fails for any require that is placed in the .rubocop.yml config file, works fine when using the cli argument $ rubocop --require rubocop-rails --require rubocop-performance.

This error is caused by #10845. It requires backward compatibility.

[koic]

@hiro-teaaa Can you provide configuration around require: in .rubocop.yml?

[hiro-teaaa]

@koic Thank you for checking in so quickly.

Can you provide configuration around require: in .rubocop.yml?

Sure, here it is

require:
  - rubocop-rails

AllCops:
  TargetRubyVersion: 3.1.1
~~~

Is it enough?

[koic]

@hiro-teaaa OK, It was reproducible. Thank you!

[ShockwaveNN]

@koic I got similar issue with rubocop-performance

Mine .rubocop.yml is here

You could checkout this project, it's fully opensource and failing with latest update

[koic]

JFYI, RuboCop 1.34.1 has been released. Thank you.

[ShockwaveNN]

@koic Thanks for quick fix

It fails for me with rubocop-performance:

# .rubocop.yml
require:
- rubocop-rake
- rubocop-rails
- rubocop-performance

# Gemfile
  gem 'rubocop', require: false
  gem 'rubocop-performance', require: false
  gem 'rubocop-rails', require: false
  gem 'rubocop-rake', require: false

$ bundle exec rubocop
cannot load such file -- rubocop-performance
/home/oleg/.rbenv/versions/3.2.1/lib64/ruby/gems/3.2.0/gems/rubocop-1.45.1/lib/rubocop/feature_loader.rb:46:in `rescue in rescue in load'
/home/oleg/.rbenv/versions/3.2.1/lib64/ruby/gems/3.2.0/gems/rubocop-1.45.1/lib/rubocop/feature_loader.rb:39:in `rescue in load'

rubocop-rake and rubocop-rails work ok, but not rubocop-performance

$ bundle exec rails c
Loading development environment (Rails 7.1.0.alpha)
[1] pry(main)> require 'rubocop-performance'
=> true

rubocop-1.45.1, bundler 2.4.7, rails master, ruby 3.2.1

Still getting such error with v1.60.2.
I'm adding new rubocop extentions to my Gemfile (ex. 'rubocop-rails') and then to the .rubocop.yml.
And when I try to execute rubocop - oops! cannot load such file.

But! I was able to fix this with rubocop --restart-server.
In the docs I found this: https://docs.rubocop.org/rubocop/usage/server.html#restart-server

The started server does not reload the configuration file. You will need to restart the server when you upgrade RuboCop or change the RuboCop configuration.
