Pip error - could not find a version that satisfie

问题:

Ansible requires Python junos-eznc module:

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

It can be installed using pip install junos-eznc

However, when running sudo pip install junos-eznc - I get this:

Collecting junos-eznc

  Could not find a version that satisfies the requirement junos-eznc (from versions: )
No matching distribution found for junos-eznc

Can anyone point me in the right direction?

I did find this article: https://github.com/Homebrew/legacy-homebrew/issues/41253

I tried renaming my files and still no luck:

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

回答1:

The warning message you get is:

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

And you indeed get the SSL verification error:

certificate verify failed

Solution: change the system date to current.

You also get two warnings (likely non-critical) with a suggestion to upgrade your Python:

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

Solution: upgrade the Python.
