bundler changes in Fedora 28

Monday, 16 July 2018

Hi,

anybody know what changed so that bundler now tries to install either 
via `sudo` or in `vendor/bundle`?

Any ideas how to restore old behavior where gems were installed 
user-wide in `~/.gem`?

P.S. I presently do this hack

 > export BUNDLE_PATH=$(ls -t -U | ruby -e 'puts Gem.user_dir')
 > export PATH="$PATH:$BUNDLE_PATH/bin"
