Ошибка в composer

[detected]

Пытаюсь установить такие виджеты (пробовал и composer.json записать)
composer require 2amigos/yii2-date-time-picker-widget:~1.0
composer require trntv/yii2-datetime-widget
Выдает такую ошибку:
Installation failed, reverting ./composer.json to its original content.
[Composer\Repository\InvalidRepositoryException]
No valid bower.json was found in any branch or tag of https://github.com/FezVrasta/popper.js.git, could no
t load a package from it.
Подскажите как ее решить

Решил проблему удалив папку vendor и в консоли прописав - composer update
