Run the following commands:
composer require drupal/config_enforce
composer require --dev drupal/config_enforce_devel
composer config extra.enable-patching "true"
This should result in the following in your project’s composer.json:
"require": {
"drupal/config_enforce": "^1.0",
[...]
"require-dev": {
"drupal/config_enforce_devel": "^1.0",
[...]
"extra": {
"enable-patching": true,
[...]
Then enable config_enforce by making it a dependency of your installation profile, a custom “site” module, on the modules admin page, or via Drush:
drush pm-enable -y config_enforce
