python3.7 pypi-server: SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] проверка сертификата не удалась: невозможно получить сертификат локального эмитента

Question

Я хотел бы развернуть свой блог (на основе python3.7 и django2.0) на сервере (centos6.), И я создал виртуальную среду (на основе python3.7). после установки pypi-sever я запускаю pypi-сервер в терминале, чтобы проверить, работает ли он. К сожалению, эта команда не работает. Я нашел много методов, включая обновление openssl, setuptools и скоро, но они не работают.

Может кто-нибудь посоветовать, что еще можно попробовать ??

    ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1045)

Answer 1

Я не знаю, какой модуль вы используете, но у меня возникли проблемы с ssl.SSLCertVerificationError: Не удалось проверить сертификат [SSL: CERTIFICATE_VERIFY_FAILED]: также не удалось получить сертификат локального эмитента (_ssl.c: 1045). Вот что я должен был сделать с импортированной библиотекой запросов

try:
    req = requests.get(i, headers=headers)
    text = req.text
except requests.exceptions.SSLError as error:
    print("SSL request error.", i)
    pass

Это обходной путь, но я попробовал весь pip install certifi, и он никогда не работал для меня.
