Python Pip错误-找不到满足junos eznc要求的版本

Ansible需要Python junos eznc模块：

junos eznc>=1.2.2是必需的，但似乎未安装

可以使用pip安装junos eznc安装它

但是，在运行sudo pip install junos eznc时，我得到以下信息：

Collecting junos-eznc
/usr/lib/python2.6/site-packages/pip/_vendor/requests/packages/urllib3/connection.py:279: SystemTimeWarning: System time is way off (before 2014-01-01). This will probably lead to SSL verification errors

谁能给我指出正确的方向吗

我确实发现了这篇文章：

我尝试重命名我的文件，但仍然没有成功：

]$ls
ca-bundle999.crt  ca-bundle999.trust.crt  ca-bundle.jks  exim.pem  localhost.crt  make-dummy-cert  Makefile  renew-dummy-cert

您收到的警告消息是：

2014年1月1日之前的系统时间已经过了很久。这可能会导致SSL验证错误

您确实会遇到SSL验证错误：

证书验证失败

解决方案：将系统日期更改为当前日期

您还收到两条警告，建议升级Python，这两条警告可能不重要：

您可以升级到较新版本的Python来解决此问题

---

解决方案：升级Python。

能否将“openssl s_client-showcerts-connect pypi.Python.org:443”的输出粘贴到某个地方？您向错误的受众提出了错误的问题。它与Ansible无关-您没有安装所需的Python模块，因此在未安装模块时会抛出一个错误-它没有任何问题。您真正的问题是，由于您发布的错误消息中给出的原因，您的pip Python包管理器无法验证SSL证书。您的设备似乎被置于防火墙或某个代理之下，无法访问pypi.Python.org下载包。你能检查curl-Is的输出吗https://pypi.python.org/simple/pip/I 确实更改了日期，这似乎停止了错误-然后pip尝试安装正在收集的pycparser>>>>>>>>>>>>然后盒子就死掉了！我再也无法访问它了：有什么想法吗？为什么？
