I have this play in my ansible playbook
- name: Setup virtualenv
pip:
requirements="/vagrant/webapp/requirements/{{ requirements_filename }}"
virtualenv="$HOME/.envs/{{ project_name }}"
However, I am receiving a Permission denied error. It seems like ansible is trying to install the package into the system path and not into the virtualenv.
Here's the full traceback:

Set up virtualenv¶After you install virtualenv, you can create a “virtual environment” to host your local copy of Ansible. This command creates a directory called myansible in your current working directory. This directory contains a copy of Python that will install modules in the myansible directory.
Any ansible operation requires python on the target node except the raw and script modules. Please note that these two modules are primarily meant to install ansible requirements (i.e. Python and its mandatory modules) on targets where they are missing.
The PermissionError: [errno 13] permission denied error occurs when you try to access a file from Python without having the necessary permissions. To fix this error, use the chmod or chown command to change the permissions of the file so that the right user and/or group can access the file.
I solved the problem by setting the path explicitly and not using the $HOME variable.
- name: Setup virtualenv
pip:
virtualenv="/home/vagrant/.envs/{{ project_name }}"
requirements="/vagrant/webapp/requirements/{{ requirements_filename }}"
