В качестве фона я использую macOS и развертываю приложения Python в AWS Elastic Beanstalk (EB).
Моему приложению не требуется libxml2-devel или libxslt-devel для локального запуска, но при отправке в Amazon EC2 и libxml2-devel, и libxslt-devel по какой-то причине становятся зависимостями. Через SSH я могу установить оба, используя sudo yum install -y libxml2-devel libxslt-devel. Это проблема, которую я могу исправить, или это проблема с AWS EB?
Кроме того, я устал удалять, а затем устанавливать как libxslt, так и libxml2, чтобы получить привязки libxml2 Python, и это не решило проблему.
brew uninstall libxslt
brew uninstall libxml2
brew install libxml2 --with-python
brew link --force libxml2
brew install libxslt
brew link --force libxslt
