Python virtualenv安装库报错SSL: CERTIFICATE_VERIFY_FAILED

问题描述

使用pip按照virtualenv报错,如下:

pip install virtualenv
Collecting virtualenv
/opt/python27/lib/python2.7/site-packages/pip/_vendor/requests/packages/urllib3/util/ssl_.py:315: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform. This may cause the server to present an incorrect TLS certificate, which can cause validation failures. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#snimissingwarning.
  SNIMissingWarning
  Could not fetch URL https://pypi.python.org/simple/virtualenv/: There was a problem confirming the ssl certificate: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590) - skipping

解决办法

使用–trusted-host命令行选项

pip --trusted-host pypi.python.org install virtualenv
