Вопрос:
Это мой процесс.
Я запускаю новый aws t2.micro ec2 на ubuntu20 и запускаю этот скрипт
sudo apt-get update
sudo apt-get install gcc
sudo apt-get install python3.9
sudo apt-get install python3.9-venv
curl --silent --show-error --retry 5 https://bootstrap.pypa.io/get-pip.py > get-pip.py
python3.9 get-pip.py
sudo apt-get install python-dev
sudo apt-get install python3-dev
python3.9 -m pip install --upgrade pip
python3.9 -m pip install --upgrade pip setuptools
python3.9 -m pip install --upgrade wheel
python3.9 -m pip install testresources
sudo apt-get install build-essential
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev wget liblzma-dev lzma
sudo apt-get install python3-devel
python3.9 -m pip install p5py
python3.9 -m pip install PEP517
python3.9 -m pip install py-find-1st
Последняя строка — это проблема
Я получаю этот вывод (ошибка внизу, я включил больше вывода, если это полезно, пришлось немного обрезать вывод)

Комментарии:
1. Возможно
python3-dev, сначала попробуйте установить сsudo apt-get install python3-devпомощью .2. @PApostol Это в списке команд, которые я пробовал, за исключением того, что это
aptвместоapt-get3. Вы проверили багтрекер? Это скорее похоже на ошибку, чем на вопрос о программировании. В любом случае, действительно ли отсутствует отсутствующий файл или он есть? Какую версию
python3-devвы установили?
Ответ №1:
Похоже, это проблема с модулем, который вы пытаетесь установить, а не с самим заголовком. Py-find-1-й-довольно экзотический модуль (9 звезд на GitHub на момент написания статьи), и о проблеме сборки такого рода уже сообщалось.
Решения:
Установите libpython3.9
sudo apt install libpython3.9-dev
Изменить: это решение сработало, в операции отсутствовал include/python3.9/Python.h заголовок, который находится в libpython3.9-dev .
Забудьте об этом модуле
Модуль реализует одну функцию для «поиска первых индексов без необходимости считывания всего массива», которая (частично) может быть реализована как:
def find_1st(X):
ind = np.flatnonzero(X < 0.)
if len(ind) :
return ind[0]
else:
return -1
Проблема в том, что это считывает полный массив. Если ваши массивы слишком велики, вы можете рассмотреть возможность выполнения этого в цикле.
Комментарии:
1. Эффективность, скорее всего, действительно важна в моем случае, один из участников этого модуля является основным сопровождающим другого репозитория с открытым исходным кодом, над которым я работаю, и я предполагаю, что он реализовал бы это решение, если бы оно было жизнеспособным. Я все
sudo apt install libpython3.9-devже попробую2. Я также подробно описал свою проблему в качестве комментария по этому вопросу
3. Так
sudo apt-get install libpython3.9-devсработало. Мои знания в этой области ограничены, поэтому мне интересно, как вы подумали, что это может быть решением?4. @Сэм Рад это слышать! Libpython3.9-dev содержит файлы заголовков, статическую библиотеку и инструменты разработки для создания модулей Python. Компилятор искал
include/python3.9/Python.hи не нашел бы его — отсюда и ошибка.
Ответ №2:
Чтобы заставить это работать на CentOS, так как этот пост постоянно появлялся во всех моих результатах Google.
Надеюсь, это поможет кому-то еще установить эту раздражающую библиотеку!
sudo yum install gcc
sudo yum install gcc-c
Комментарии:
1. Просто любопытно, вы устанавливаете эту библиотеку для использования
freqtrade?2. @Sam, это правильно, запускал его некоторое время после вышеупомянутого исправления, чтобы посмотреть, как он работает, но больше не использовал его.
3. Мне также пришлось установить
python39-devel, чтобы это работало, но я использовал только Redhat, а не CentOS. Я также обновил сценарий настройки freqtrades, чтобы он работал для операционных систем Rhel
