SO выход просто зависает и не устанавливается ничего.

Вот некоторая информация о машине:

Answer 1

Слишком низкая репутация комментировать. У меня возникли проблемы с установкой lxml на Centos 7, но он был успешно использован в ответе Найроби в post Jimothy, связанном с выше. yum install libxslt-devel libxml2-devel

Надежды Это помогает людям, которые находят этот пост в будущем.

Answer 2

Установка этих зависимостей первые

sudo yum install libxml2 libxml2-devel libxml2-python libxslt libxslt-devel 

pip install lxml or easy_install lxml 

Рекомендуется использовать virtual environment. Это помогает изолировать среды python.
