lxml никогда не закончит строительство на ubuntu

Я запускаю ubuntu 14.04 LTS и python 2.7.5 на vwmare.

Когда я запускаю:

sudo pip install lxml

Я получил:

Collecting lxml
  Using cached lxml-3.4.4.tar.gz
Building wheels for collected packages: lxml
  Running setup.py bdist_wheel for lxml

которая работает вечно.

Я не могу найти никаких ресурсов, связанных с этим, и у меня нет опыта с подобными ошибками.

Обратите внимание, что приведенное ниже решение не работает:

sudo apt-get build-dep -y lxml;
pip install lxml

Я также пробовал:

sudo apt-get install -y build-essential python-dev

ОТВЕТЫ

Ответ 1

Обратите внимание: если вы запустили top в отдельном терминале, вы заметите, что ваша система занята построением пакета lxml:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1645 root 20 0 322224 305740 5384 R 100.0 29.8 3:27.47/usr/lib/gcc/arm-linux-gnueabihf/5/cc1 -quiet -I/usr/include/libxml2 -I src/lxml/includes -I/usr/include/python2.7 -Imultiarch arm-linux-gnueabihf -D_REENTRANT -D...

Если вы строите VM или SBC с ограниченными ресурсами, это может занять некоторое время...

Ответ 2

Я запустил это на ВМ с 768 МБ ОЗУ (которое я не заметил, это было значение, которое я установил), и это заняло несколько часов и не закончилось.

Изменение оперативной памяти на 3 ГБ завершило работу через несколько минут после перезапуска и повторной попытки.

Ответ 3

Попытка установить это на Raspberry Pi 3 B+ на Kali Linux. Как долго я должен ждать, прежде чем я знаю, что это просто висит.

Ответ 4

Я столкнулся с той же проблемой, когда пытался "установить pip" пакет, который зависит от lxml на Raspberry Pi 1 B+. Через несколько часов (и несколько попыток) соединение SSH оборвалось без завершения сборки колеса. Это похоже на нехватку памяти.

Я решил установить готовые двоичные пакеты, используя apt install python-lxml или apt install python3-lxml соответственно.
