本文介绍了解决使用pip7.1.2版本安装第三方模块时出现的SSL警告的方法。主要原因是urllib3的SSL配置出现问题导致连接失败。通过安装特定的依赖包可以解决此问题。

在用pip7.1.2版本安装第三方模块时出现了如下警告：

...
_vendor/requests/packages/urllib3/util/ssl_.py:90: 
InsecurePlatformWarning: A true SSLContext object is not
available. This prevents urllib3 from configuring SSL
appropriately and may cause certain SSL connections to fail
...

提示是由于urllib3的SSL连接失败

解决方法：
1, 安装python-devel libffi-devel openssl-devel

# yum install python-devel libffi-devel openssl-devel

2, 安装pyopenssl ndg-httpsclient pyasn1

# pip install pyopenssl ndg-httpsclient pyasn1

End !

pip 21.0将在2021年1月停止对Python 2.7的支持，所以你也需要升级pip。同时，错误还提示SSL连接可能存在问题，因为当前平台不安全，建议升级到新版本的Python来解决这个问题。你可以点击提供的链接获取更多信息。

这个错误提示是因为您使用的 Python 版本过低（Python 2.7 已经不再维护），建议升级到 Python 3.x 版本。...另外，关于 SSL 警告的问题，可以参考提示中提供的链接，升级 urllib3 库或升级 Python 版本即可解决。
