Two versions of bundler installed and using the wrong one - ruby-on-rails

Question

I have the right version of Bundler installed:
docker#f5990915a8ae:/usr/src/app$ bundler version
Bundler version 2.2.17 (2021-05-05 commit 69cbd6e10e)
But when I run the db:migrate it seems that is using another one:
Warning: the running version of Bundler (2.1.4) is older than the version that created the lockfile (2.2.17). We suggest you to upgrade to the version that created the lockfile by running gem install bundler:2.2.17.
This is my gem environment for the app:
RubyGems Environment:

These are the two bundler versions installed:
home/docker/.gem/specifications/bundler-2.2.17.gemspec
usr/lib/ruby/gems/2.7.0/specifications/default/bundler-2.1.4.gemspec
How do I make the db:migrate use the right one?

Answer 1

change to
bundle exec rake db:migrate
or change bundler version in Gemfile.lock
