Unable to run 'expect' module

[Alain Désilets]

I am trying to run a playbook (see end of the post), which invokes the 'expect' module.

But when I run it, I get error:

TASK [Run anaconda installation script] ****************************************

fatal: [127.0.0.1]: FAILED! => {"changed": false, "msg": "The pexpect python module is required"}

Yet, the 'pip' task that is supposed to install pexpect runs without error.

What am I doing wrong?

Thx.

Alain Désilets

Content of the playbook:

---

- name: Run Anaconda shell

  hosts: all
  vars:
      conda_home: "~/anaconda2-NEW"
      conda_inst_sh_path: /path/to/Anaconda2-2018.12-MacOSX-x86_64.sh

  tasks:

    - name: install pexpect
      pip:
        name: pexpect
      become: yes
      become_user: root

    - name: Run anaconda installation script
      expect:
        command: "sh {{conda_inst_sh_path}}"
        responses:
          (?i)password: "MySekretPa$$word"
      become: yes
      become_user: root

Install "expect" using "yum" rather than "pexpect" using "pip".

Thx Diptajeet,

I am on OSX, so I can't install with yum. I did however install 'expect' using homebrew as follows:

   brew install expect

This installed v5.45.4 of expect. Yet, I still get the pexpect error message.

I see. Can you also try "brew install pexpect" and run the Ansible code.

Found it! By default, Ansible uses a particular path for finding the Python interpreter it uses to run the playbooks. This turned out to be different from the interpreter on which I had isntalled pexpect.

I fixed the issue by passing the following argument to my ansible-playbook command:

       -e 'ansible_python_interpreter=/path/to/my/python

Alright!
