python - Pip 错误 - 找不到满足 junos-eznc 要求的版本

Question

Ansible 需要 Python junos-eznc 模块:

junos-eznc >= 1.2.2 is required but does not appear to be installed.

It can be installed using pip install junos-eznc

但是，当运行 sudo pip install junos-eznc - 我得到这个:

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

This may cause the server to present an incorrect TLS certificate, which can cause validation failures. You can upgrade to a newer version of Python to solve this.

谁能指出我正确的方向？

我确实找到了这篇文章:https://github.com/Homebrew/legacy-homebrew/issues/41253

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

Answer 1

您收到的警告消息是:

System time is way off (before 2014-01-01). This will probably lead to SSL verification errors

而且您确实遇到了 SSL 验证错误:

certificate verify failed

解决方案:将系统日期更改为当前日期。

您还会收到两个警告(可能不严重)，并建议升级您的 Python:

You can upgrade to a newer version of Python to solve this.

解决方案:升级 Python。
