BackGround
Я клонировал проект из репозитория ниже и попытался выполнить его с помощью команд.
Репозиторий GitHub: https://github.com/udacity/FSND-Deploy-Flask-App-to-Kubernetes-Using-EKS
Проблема
Не удалось выполнить его без ошибок на кодах, но что-то из-за среды разработки, как OSError: [Errno 8] Exec format erro
.
Я понятия не имею, как исправить эти ошибкии, пожалуйста, дайте мне какие-либо советы и предложения.
