ssl 错误为什么用 pip 安装

Question

Im trying to install pyobjc with pip. However every time i run it i get this error. Some forums say to use --trusted as a workaround but it still doesn't work. My computer is a Mac OS Sierra version 10.12.6

My command :

$ sudo pip install pyobjc-framework-Quartz

Collecting pyobjc-framework-Quartz Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)'),)': /simple/pyobjc-framework-quartz/ Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)'),)': /simple/pyobjc-framework-quartz/ Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)'),)': /simple/pyobjc-framework-quartz/ Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)'),)': /simple/pyobjc-framework-quartz/ Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)'),)': /simple/pyobjc-framework-quartz/ Could not fetch URL https://pypi.python.org/simple/pyobjc-framework-quartz/ : There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.python.org', port=443): Max retries exceeded with url: /simple/pyobjc-framework-quartz/ (Caused by SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:833)'),)) - skipping Could not find a version that satisfies the requirement pyobjc-framework-Quartz (from versions: ) No matching distribution found for pyobjc-framework-Quartz
