Rails 5.2.0 with Ruby 2.5.1 console - `warning:` `already` initialized constant FileUtils::VERSION

Question

I\'m currently experiencing an issue with my new rails application, more specifically:

• Rails 5.2.0
• Ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwi

Answer 1

I had the same issue. The one step missing from your post is to uninstall the fileutils gem first, then gem update with the default option.

gem uninstall fileutils
Successfully uninstalled fileutils-1.1.0
gem update --default
Updating installed gems
Updating fileutils
Fetching: fileutils-1.1.0.gem (100%)
Successfully installed fileutils-1.1.0

That got rid of the verbose fileutils messages for me.

Update: Instead of gem update --default, do gem update fileutils --default. This process should work for other gems too. Thanks to Matijs van Zuijlen for this.
