Version: Docker Image `ruby:2.4.4` https://github.com/docker-library/ruby/commit/ee0b15d76c92ad221caf9afaf9b8827e7fe39f9a#diff-ff2de49361eed004fa5d18a474ece86a Please check this commit diff. I can't exec `rails s` after `bundle install` recently. I think it's caused by `$BUNDLE_BIN` removed. And not exist path "`$BUNDLE_PATH/gems/bin`".
