All actions with the pip module (other than creating the venv) apply to the
user context and not the venv on a Mac. The details below are for the pip
module. Running the commands when logged into the system works as expected
and using those commands with both the command and shell modules results in
the same outcome as the pip module. There's something different about the
way it's being interpreted through Ansible. The same role works fine in
Linux. Have tried this on 2 different Macs, both running Catalina.
$ ansible --version
ansible [core 2.11.6] config file = None configured module search path =
['/Users/spitzer/.ansible/plugins/modules',
'/usr/share/ansible/plugins/modules'] ansible python module location =
/Users/spitzer/.virtualenvs/ansible460/lib/python3.8/site-packages/ansible
ansible collection location =
/Users/spitzer/.ansible/collections:/usr/share/ansible/collections
executable location = /Users/spitzer/.virtualenvs/ansible460/bin/ansible
python version = 3.8.12 (default, Sep 1 2021, 07:26:09) [Clang 11.0.3
(clang-1103.0.32.62)] jinja version = 3.0.1 libyaml = True
So, a minimal role to duplicate this is:
---
# Test pip role
- name: Create venvs root dir
file: path: "{{ temp_dir }}/venvs"
state: directory mode: "0755"
- name: pip install requests
pip: name: requests
state: latest
virtualenv: "{{ temp_dir }}/venvs/test-env"
The pip install does create the venv where expected and all permissions
look good, but during the install of 'requests' it gives me "Defaulting to
user installation because normal site-packages is not writeable" and then
installs it under user instead of the venv.

On the same machine, doing the following by hand works:
$ cd ~/ansible_tmp
$ virtualenv test-env
$ ~/ansible_tmp/test-env/bin/pip3 install requests
Running those exact commands using the shell module still results in the
user install. Have also tried with pip module, explicitly setting the pip3
binary with the same result.
Also, I completely removed the test-env directory before every test. Also,
also, I've done this with the built-in Python 3.8 install, as well as the
homebrew and macports 3.8 installs and forcing the correct python3 binary
in the pip module. All had the same results.
Does anybody have any idea what I'm doing wrong here?
Thanks
