Ran into this, and the solution here works: https://stackoverflow.com/questions/51334732/rails-5-2-0-with-ruby-2-5-1-console-warning-already-initialized-constantruby
I understand 1.0.2 stays installed as the default, 1.1.0 being installed too. Hence the issue.app
When installed automatically, I get the warnings. Following command shows (new rails app, 2.5.1) :this
gem list | grep fileutils
fileutils (1.1.0, default: 1.0.2)url
Then doing:.net
gem uninstall fileutils
gem update fileutils --defaultget
makes the warnings disappear. And btw, it shows:it
gem list | grep fileutils
fileutils (default: 1.1.0, default: 1.0.2)io
Hope it will help fixing this annoyance. Sorry I cannot be of more help, not really a wizard with those versioning topics!console
