junos-eznc required but does not appear to be installed

[Anish Patel]

Hi all,

I am getting the following error when trying to run a playbook

NY-APatel-home:ansible anish.patel$ ansible-playbook -i dev interface.yaml

PLAY [link-switch] *******************************************************************************************

TASK [Install JUNOS] *****************************************************************************************
fatal: [cart-acx]: FAILED! => {"changed": false, "failed": true, "msg": "junos-eznc is required but does not appear to be installed. It can be installed using `pip  install junos-eznc`"}

PLAY RECAP ***************************************************************************************************
cart-acx                   : ok=0    changed=0    unreachable=0    failed=1 

However junos-eznc is installed

NY-APatel-home:ansible anish.patel$ pip list

Thanks for the quick reply Nitin.

Here is my playbook just for reference - when i use the junos_command modules I don't get any issues.
- hosts: link-switch
  roles:
  - Juniper.junos
  gather_facts: false
  connection: local

  tasks:
  - name: Install JUNOS
    junos_package:
      force: false
      reboot: false
      src: /var/tmp/jinstall-ppc-16.2R1.6-signed.tgz
      provider: "{{ credential }}"

NY-APatel-home:~ anish.patel$ which python
/usr/bin/python

worth noting I am doing this on a mac pro just for Proof Of Concept before I put this on ubuntu somewhere

I'll take a look at the reference you sent.

Thanks again!
