I have this problem too

The problem seems to be caused when you install rubocop using Bundler. Initially, (as per the instructions on the project's homepage) I had the following in my Gemfile:

gem 'rubocop', '~> 0.62.0', require: false

When I removed this line from the Gemfile and installed rubocop via:

gem install rubocop

The error went away.

I have the following error:

-s/--stdin requires exactly one path, relative to the root of the project. RuboCop will use this path to determine which cops are enabled (via eg. Include/Exclude), and so that certain cops like Naming/FileName can be checked.

Look for a .rubocop arguments file in your project directory and remove it, Rubocop does not allow the use of stdin in combination with an arguments file, alternatively you can put your configuration on a .rubocop.yml file.

I was getting the same error @luciuschoi mentioned.

In my case it was happening because I moved a project into an iCloud folder on MacOS. The full path had unescaped, special characters in it. It included a space ( ) and some tildes (~) - the latter I realize is silly to have in a directory name at all, but just FYI. The full command was bundle exec rubocop --stdin /Users/flip/Library/Mobile Documents/com~apple~CloudDocs/Clients/REDACTED/app/models/concerns/user_sync.rb --force-exclusion --auto-correct.

I resolved it simply by moving the project back out of my iCloud drive, but I thought this was worth mentioning.

Thank you @flipsasser !!! I wasted four hours today when all I had to do was rename the root of my project from .../Rails Programs to .../RailsPrograms
