Ansible lineinfile module: unsupported parameter for module: path

Is Ansible giving you the error unsupported parameter for module: path when you’re using lineinfile?

Check your Ansible-version!

You probably used path (as of version 2.3) instead of dest.

$ ansible --version
ansible 2.2.1.0
  config file =
  configured module search path = Default w/o overrides

As the Ansible documentation states:

As of Ansible 2.3, the dest option has been changed to path as default, but dest still works as well.

Solution: change dest into path

This fixed it for me. Now I can ensure composer is in my path.

# file composer.yml

# add composer to $PATH
- lineinfile:
    regexp: 'export PATH=".*/project/vendor/bin.*"'
    line: 'export PATH="$PATH:/project/vendor/bin"'
    state: present
    dest: /home/vagrant/.bashrc

Explanation of the parts:

• regexp: the regular expression to look for. The line that matches will be used for present or absent
• line: this is the line that will be inserted/replaced into the file
• state: whether or not line should be there. Tip: for advanced usage, look at backrefs for changing parts of the line.
• dest: the file we want the line in
