在用pip7.1.2版本安裝第三方模組時出現了如下警告：

<code class="hljs avrasm has-numbering">/usr/lib/python2<span class="hljs-number">.7</span>/site-packages/pip-<span class="hljs-number">7.1</span><span class="hljs-number">.2</span>-py2<span class="hljs-number">.7</span><span class="hljs-preprocessor">.egg</span>/pip/_vendor/requests/packages/urllib3/util/ssl_<span class="hljs-preprocessor">.py</span>:<span class="hljs-number">90</span>: <span class="hljs-label">InsecurePlatformWarning:</span> A true SSLContext object is not available.

提示是由於urllib3的SSL串連失敗 解決方案

首先安裝python-devel libffi-devel openssl-devel

yum install python-devel libffi-devel openssl-devel

之後在安裝pyopenssl ndg-httpsclient pyasn1

pip install pyopenssl ndg-httpsclient pyasn1

在運行pip就不會出現警告了
