Pip: SSL: CERTIFICATE_VERIFY_FAILED مع Python 3.6.0

• إصدار النقطة: 9.0.1
• إصدار Python: 3.6.0
• نظام التشغيل: macOS Sierra

وصف:

أحصل على خطأ في الشهادة pypi.python.org عند تشغيل pip install -U channels . لا أعرف ما إذا كانت المشكلة متعلقة بـ pip أو Python 3.6.0 أو شيء آخر. لقد جربت الاقتراحات التالية ولكن لم ينجح أي منها.

pip --trusted-host pypi.python.org install -U channels

export PIP_CERT=/Users/user/Desktop/certificate_which_i_obtained_from_pypi_dot_python_dot_org.crt
pip install -U channels

cacert.pem هي شهادة curl .
pip --cert /Users/user/cacert.pem install -U channels

أظن أيضًا أن المشكلة قد يكون لها علاقة بـ Python 3.6.0. لأنه ضع في اعتبارك المخرجات التالية:

user<strong i="25">@host</strong>:~$ python
Python 3.6.0 (v3.6.0:41df79263a11, Dec 22 2016, 17:23:13)

>>> context.cert_store_stats()
{'x509': 0, 'crl': 0, 'x509_ca': 0}
>>> context.get_ca_certs()
[]
