I wish to move the bootstrap theme from the repository
located in the folder
theme/custom to be a dependency in
I’ve checked that the current version
rm -rf web/theme/custom/bootstrap
composer require drupal/bootstrap:8.x-3.16
^^-> wrong syntax and have decided to just
composer require drupal/bootstrap
Now I need to downgrade the version of drupal/bootstrap in composer.json
composer update --lock
But I got an error:
Nothing to modify in lock file Unable to find a compatible set of packages based on your non-dev requirements alone. Your requirements can be resolved successfully when require-dev packages are present. You may need to move packages from require-dev or some of their dependencies to require. Problem 1 - Root composer.json requires drupal/bootstrap 3.16, found drupal/bootstrap[3.23.0] but it does not match the constraint.
Any hints would appreciate.
