Ansible_python_interpreter issues

Hello,

I keep getting the following errors when I run my cisco playbook:

Failed to import the required Python library (ansible-pylibssh) on itbckt-01’s Python /usr/bin/python3.12. Please read the module documentation and install it in the appropriate location. If the required library is installed, but Ansible is using the wrong Python interpreter, please consult the documentation on ansible_python_interpreter

ansible --version shows

 config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/user/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.12/site-packages/ansible

  jinja version = 3.1.2

Ive set the ‘ansible_python_interpreter’ everywhere. In the play file like this:


- name: capture show output
  hosts: routers
  gather_facts: no
  connection: network_cli
  vars:
    ansible_python_interpreter: /usr/bin/python3.6
    ansible_network_os: cisco.ios.ios

  tasks:
    - name: show run
      ios_command:
        commands:
        - show version
      register: config

    - name: save output to local directory
      copy:
       content: "{{ config.stdout | replace('\\n', '\n') }}"
       dest: "show-output/{{ inventory_hostname }}.ios

in the host file:


[routers]
172.x.0.4
172.x.0.2
172.x.0.1

172.28.0.4
172.28.0.5



#ansible_python_interpreter: /usr/bin/python3.6

[all]
ansible_connection=ssh
ansible_python_interpreter: /usr/bin/python3.6

ansible_connection: ansible.netcommon.network_cli
ansible_network_os: ios
ansible_network_os: nxos

It still complains.

please help!

Ansible is using python3.12

So you need to remove this

From the error message, it looks like you are missing ansible-pylibssh

which should be installed with the same Python interpreter that Ansible is using.

python3.12 -m pip install ansible-pylibssh
3

sudo python3.12 -m pip install ansible-p ylibssh
/bin/python3.12: No module named pip3

I keep getting this. And ive installed the package with:

sudo pip3 install ansible-pylibssh

You don’t want to use sudo when installing packages with pip.

What is the output of $ pip3 --version ?

5

Either way, I’m pretty sure pip3 is pointing to python3.6, so this does not help since Ansible is using Python3.12.

I see that you are on rhel 8.

And I guess you installed python3.12 with dnf/yum, but you probably didn’t install pip since this is failing:

So you want to install pip for python3.12 and then ansible-pylibssh.

$ sudo dnf install python3.12-pip
$ python3.12 -m pip install ansible-pylibssh

Hi so if i wanted to download ansible-pylibssh offline, would I get these files here? ansible-pylibssh · PyPI

If so how would i install it?
it looks like its already installed with pip 3. can I just make ansible use 3.6 python version?


pip3 show ansible-pylibssh

pip3 --version
pip 9.0.3 from /usr/lib/python3.6/site-packages (python 3.6)

Yes.

Something like this:

python3 -m pip install --user --no-index --find-links . --upgrade ansible_pylibssh-1.2.2-cp312-cp312-manylinux_2_28_x86_64.whl

Newer versions of Ansible (for the controller) do not support that.

I suggest you take a look at this document:
https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html#installing-and-upgrading-ansible-with-pip

I also recommend creating and activating a virtual environment in Python before pip installing Ansible and other packages.

Ok so i did try that for that specific version. I just copied it on roots dir and got the following:

ansible_pylibssh-1.2.2-cp312-cp312-manylinux_2_28_x86_64.whl is not a supported wheel on this platform.

That was just an example. You will have to get the compatible version with your OS/platform.
