What does bundle exec rake db:migrate
mean? Or just bundle exec rake <command>
in general?
I understand that bundle
takes care of maintaining things in the Gemfile. I know what the word “exec” means. I understand that rake
maintains all the different scripty things you can do, and I know that db:migrate
is one of those. I just don’t know what all these words are doing together. Why should bundle
be used to execute rake
to execute a database migrate?
