Ansible 2.0.0.2中replace模块报path参数不支持的问题求助

Hey there! Let's work through your Ansible problem step by step. You've hit two key issues with your playbook, and we'll resolve both to get your version number update working.

What's Going Wrong? #

1. Unsupported path Parameter: Ansible 2.0.0.2's replace module doesn't recognize the path argument—this was added in later versions (around 2.3+). Older versions use dest (or name) instead.
2. Incorrect Variable Handling: Your regex and replacement value aren't referencing variables properly, plus the version number's dots are special regex characters that need escaping.

Step-by-Step Fixes #

1. Swap path for dest #

In Ansible 2.0.x, the replace module uses dest to specify the target file. Update that line in your playbook, and the parameter error will disappear.

2. Fix Variable References & Regex Escaping #

• Variables in Ansible need to be wrapped in {{ }}—so prev_version|string becomes {{ prev_version }}.
• The . in version numbers matches any character in regex, which means your current regex might accidentally match other text. Use the regex_escape filter to automatically escape all special characters in your old version string.

Updated Playbook (test.yml) #

- name: Update the provided system to the next version
  hosts: localhost
  run_once: true
  vars:
    prev_version: "{{ PREVIOUS_VERSION }}"
    next_version: "{{ NEXT_VERSION }}"
  tasks:
    - name: Update the software version
      replace:
        dest: /home/hamza/TrainingWorkspace/Ansible/application_config.txt
        regexp: "{{ prev_version | regex_escape }}"
        replace: "{{ next_version }}"

Test the Fix #

Run your original command again—it should work now:

ansible-playbook --connection=local --inventory 127.0.0.11, test.yml --extra-vars '{"PREVIOUS_VERSION":"2020.2.2", "NEXT_VERSION": "2020.99.99"}'

After execution, check your application_config.txt file—you should see:

version_info: "2020.99.99"

Quick Note #

If you can, consider upgrading your Ansible version to a newer stable release (like 2.10+). Newer versions support the path parameter, have more features, and fewer compatibility quirks like this one.
