Установка Python scanpy не удалась, хотя llvmlite уже установлен - ОШИБКА: команда выполнена с ошибкой со статусом выхода 1

Question

Я хочу установить scanpy (на Python 3.9.1, Windows 10).

Прежде чем пытаться установить scanpy, я проверяю, что с llvmlite все в порядке, которое я ранее устанавливал, если llvmlite не удалось установить. Ошибка при создании llvmlite:

      C:\Users\plain>pip show llvmlite
Name: llvmlite
Version: 0.35.0

Но когда я затем пытаюсь установить scanpy, он работает нормально, пока не дойдет до llvmlite:

      Running setup.py install for llvmlite ... error

Как мне двигаться дальше? Спасибо!

Answer 1

Когда у меня возникают проблемы с установкой модуля, мне очень помогает установка winpip.

pip install winpip

установка winpip (выбираемый модуль)

В большинстве случаев это поможет
