解决python安装pip install mock报Could not fetch URL https://pypi.org/simple/mock/: There was a problem confirmin g the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443)的问题

问题：使用python2安装mock包，报

Could not fetch URL https://pypi.org/simple/mock/: There was a problem confirmin
g the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retri
es exceeded with url: /simple/mock/ (Caused by SSLError(SSLError(1, u'[SSL: CERT
IFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)'),)) - skipping
ERROR: Could not find a version that satisfies the requirement mock (from versio
ns: none)

执行pip2 --trusted-host pypi.python.org install mock扔报同样的错误
