Невозможно установить Python на Windows 8

Question

Недавно я решил обновить Python 2.7 до Python 3.4 на моем ноутбуке с Windows 8. Поэтому я удалил Py2.7, скачал MSI-файл с сайта python и запустил его. Я обнаружил, что каждый установщик, который я пробовал как для 3.4.1, так и для 3.4.0, выдавал ошибку, сообщающую, что часть установщика не работает. Точное сообщение об ошибке: «Существует проблема с этим пакетом установщика Windows. Программа, запущенная как часть установки, завершилась не так, как ожидалось. Обратитесь в службу поддержки или к поставщику пакетов. «У меня никогда раньше не было таких проблем, и уж точно не было с Python. Кто-нибудь знает хороший способ попробовать и отладить это? Он сохраняется во многих инсталляторах, и я уверен, что это должно быть что-то в моей системе.

РЕДАКТИРОВАТЬ: Спасибо за совет о файле журнала. Он очень большой (больше, чем мне разрешено размещать на этом сайте ~ 320 тыс. Символов). Вот бит сразу после того, как он говорит «фатальная ошибка». Это из-за запуска предложенного кода в установщике для 3.4.1 64 бит.

Answer 1

Поскольку эта проблема возникает из-за того, что pip поставляется с установщиком python 3.4, вы можете просто снять галочку с опции установки pip в установщике и попробовать позже установить pip вручную.

Answer 2

Я столкнулся с той же или, по крайней мере, похожей ошибкой, но не смог найти решение. Я только что удалил Python 3.4.1 и пытался установить Python 3.4.2.

Я обнаружил три разные проблемы в моей среде, но № 3 - это то, что действительно исправило мою проблему. Первые два пункта не имели большого значения для моей ситуации, я просто включил их в качестве дополнительных опций / идей для других (особенно при установке второй версии Python и т.д.).

1. Оставшиеся переменные среды. У меня были переменные среды из установочного набора 3.4.1. При установке нескольких версий это может привести к ошибке во время установки. Возможно, вам придется удалить эти переменные среды.

   

2. Системный ПУТЬ. Python все еще был в системе PATH. Опять же, при установке нескольких версий, это может вызвать ошибку во время установки. Возможно, вам придется удалить эти записи из вашего PATH.

   

3. Актуальная проблема: Custom open/command в реестре. У меня есть эта запись в реестре здесь (плюс добавление .PY для PATHEXT PATHEXT), поэтому я могу запускать программы на Python, используя только app.py , вместо того, чтобы вводить PYTHON app.py

   

Проблема заключалась в том, что новая версия Python была частично установлена, а затем он пытался запустить некоторые команды Python во время установки. Из-за моей пользовательской регистрации он пытался запустить код Python, используя старый путь к python.exe, который, конечно, был удален. Таким образом, это будет терпеть неудачу каждый раз.

Таким образом, удаление пользовательской команды open/ позволило выполнить установку успешно. Я добавил его обратно после завершения установки.

Несколько вещей, чтобы отметить. У меня не было бы проблемы, если бы я не менял место установки. И я мог бы просто обновить запись open/command, чтобы она указала на новое местоположение, а не удаляла его и потом добавляла заново.

Answer 3

Ура, наконец-то, после долгих исследований, я нахожу решение. Перейдите в системный путь и удалите любой путь, который указывает на python27 или любую другую версию, и запустите установщик msi.

Answer 4

Для меня эта проблема возникла из-за того, что установщик Python обнаружил в моей системе неправильную версию hashlib, что, в свою очередь, прервало этап установки «surepip», который, к сожалению, не сообщает о полезной ошибке. Создание журнала msiexec помогло мне отследить эту ошибку.

Кажется, установщик должен быть более осторожным, чтобы использовать свой собственный hashlib.

Эта ошибка связана, и эта страница помогла мне выяснить, что это был посторонний хешлиб (хотя моя проблема была в Windows).

Answer 5

У меня нет конкретного ответа здесь, но вот несколько довольно общих шагов отладки MSI, которые могут сузить проблему:

Сначала нам нужно сгенерировать журнал установки. Команда msiexec /i installer.msi /l*v log.txt может сделать это.

Когда у вас есть журнал, первое, что вы можете сделать, - это найти Error или FatalError (как вы это сделали). Обратите внимание, что это происходит в журнале после действий отката, поэтому вам нужно прокрутить назад на многие страницы FileRemove , ComponentUnregister и т.д. На самом деле, вы можете найти более полезным поиск InstallFinalize и поиск прямо над ним (не обращайте внимания на первое вхождение вверху).

Вот интересные строки из вашего журнала ошибок:

MSI (s) (60:80) [12:14:22:868]: Executing op: ActionStart(Name=UpdatePip,,)
Action 12:14:22: UpdatePip.

Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor.  Action UpdatePip, location: C:\Python34\python.exe, command: -m ensurepip -U --default-pip 
MSI (s) (60:80) [12:14:25:627]: Note: 1: 2262 2: Error 3: -2147287038

Contact your support personnel or package vendor.  Action UpdatePip, location: C:\Python34\python.exe, command: -m ensurepip -U --default-pip 

Это интересная ошибка, и я не совсем уверен, почему python -m ensurepip -U --default-pip будет работать. Я хотел бы предложить, возможно, попытаться получить переносимую копию или скомпилировать из исходного кода, а затем запустить команду вручную, чтобы посмотреть, сможете ли вы получить больше информации. В противном случае вы можете попробовать связаться с сопровождающими через IRC, список рассылки или другим способом.

И, конечно, если вы поймете, почему, пожалуйста, оставьте здесь ответ на свой вопрос, чтобы помочь другим!
