Как установить PyMuPDF на Heroku Django
Я пытаюсь создать сценарий, который извлекает изображения из PDF, и я создал сценарий в проекте Django и добавил pymupdf в файл requirements.txt. У меня есть файл Aptfile с Mupdf и https://github.com/heroku/heroku-buildpack-apt в качестве пакета сборки вместе с heroku / python. При попытке отправить master на Heroku, Push терпит неудачу, и вот ошибка.

Решение
После некоторой отладки я решил проблему.
Проблема заключалась в новой версии PyMuPDF, поэтому вместо последней версии PyMuPdf я использовал старую версию.
В Aptfile вместо добавления Mupdf-tools добавьте
http://ftp.br.debian.org/debian/pool/main/m/mupdf/mupdf_1.14.0+ds1-4_amd64.deb
В файле requirements.txt вместо PyMuPDF добавьте
PyMuPDF==1.14.20
Это должно решить это.
У меня возникла точно такая же проблема, как вы описали.
До этого мое приложение Django Heroku работало нормально без проблем с использованием PyMuPDF / Fitz. Так что мне оставалось сделать вывод, что этот сбой сборки был совершенно новой проблемой, приведшей к некоторым изменениям.
В моем случае я недавно обновил свои зависимости, включая PyMuPDF.
Моя проблема была решена путем блокировки PyMuPDF в версии 1.16.0.
pymupdf = "==1.16.0"
Я думаю, что последняя версия на момент написания - 1.16.1 или 1.16.2.
Я не уверен на 100% в основной причине, но подозреваю, что это потому, что последняя версия PyMuPDF может не обеспечивать обратную совместимость со старыми версиями pip.
После проверки версии pip, запущенной на моем живом динамометрическом стенде Heroku, я получаю:
"Вы используете pip версии 9.0.2, однако доступна версия 20.0.2".
Если вы используете среду Heroku Python по умолчанию, то же самое может относиться к вам.
Сообщите нам, решит ли замораживание вашей версии PyMuPDF проблему и для вас!
