Why you need a bundle exec

Why you need bundle exec

$bundle exec rails g controller user

If you do, the one described in Gemfile.lock will be required.

To put it simply, if you develop and update without bundle exec, it may get stuck. So, I understood that it would be safe to develop with bundle exec, so I thought it would be good for the time being.
