Bootstrap 4 не поддерживается?

[mr.lostov]

так случилось что у меня в проекте Bootstrap 4, как мне установить ваше компонент?

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - yiisoft/yii2-bootstrap5[2.0.1, ..., 2.0.3] require bower-asset/bootstrap ^5.1.0 -> found bower-asset/bootstrap[v5.1.0, v5.1.1, v5.1.2, v5.1.3] but the package is fixed to v3.4.1 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - dicr/yii2-file[8.1.0, ..., 8.1.9] require dicr/yii2-asset ~3.0 -> satisfiable by dicr/yii2-asset[3.0.0, 3.0.1, 3.0.2].
    - dicr/yii2-asset[3.0.0, ..., 3.0.2] require yiisoft/yii2-bootstrap5 ~2.0 -> satisfiable by yiisoft/yii2-bootstrap5[2.0.1, 2.0.2, 2.0.3].
    - Root composer.json requires dicr/yii2-file ^8.1 -> satisfiable by dicr/yii2-file[8.1.0, ..., 8.1.9].

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require dicr/yii2-file:*" to figure out if any version is installable, or "composer require dicr/yii2-file:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
