`Dir.exists?` and `File.exists? were removed by ruby/ruby#5352. It will be the following error in Ruby 3.2. ```console % ruby -ve 'File.exists?("foo.rb")' ruby 3.2.0dev (2021-12-28T15:22:18Z master 39b3aa4fb3) [x86_64-darwin19] -e:1:in `<main>': undefined method `exists?' for File:Class (NoMethodError) File.exists?("foo.rb") ^^^^^^^^ Did you mean? exist? ``` And this PR enables `Lint/DeprecatedClassMethods` cop to detect these deprecated methods.

💯 would appreciate this to be done soon. |

@byroot Thank you for working on this! |

Thanks for letting me know. Unfortunately I don't have an NPM account, hence not the ownership of the package. I relayed the issue to rails-core. |

@dhh released the 5.4.4 a few minutes ago: https://www.npmjs.com/package/@rails/webpacker so you should be good now. |

Currently released stable version of webpacker (5.4.3) does not work on the newest stable Ruby (3.2.0) because webpacker 5.4.3 includes
Dir.exists?andFile.exists?that were removed in Ruby 3.2.Hence, the current situation is that Rails 6.1 users cannot upgrade to Ruby 3.2 because there's no webpacker that supports that versions stack. We could solve this situation by backporting a single commit from #3250.
Please consider merging this and cutting the version 5.4.4 release from 5-x-stable branch. Then probably people would stop complaining to the Ruby-core on the Ruby BTS about this error from webpacker... https://bugs.ruby-lang.org/issues/19352
Closes #3299
