Activeadmin: Admin::Engine(NameError) 설치 시

Active Admin을 설치하려고 할 때 이 오류가 계속 발생합니다.

rvm과 rbenv 및 다른 버전으로 시도했지만 여전히 설치할 수 없습니다. 그것은 2 일 전에 완벽하게 작동했습니다. 어떤 아이디어?

자산 생성은 설치 전에 작동하지만 설치 후(및 설치 시) 모든 것이 중단됩니다.

bundle exec rails generate active_admin:assets

내가 하려고 하는 것

bundle exec rails generate active_admin:install

젬파일

gem 'devise'
gem 'activeadmin', github: 'activeadmin'
gem 'inherited_resources', github: 'activeadmin/inherited_resources'
