klaus385 / ansible-python3-role

Ansible role for installing Python 3.

python3

This Ansible role will install Python 3, pip, and virtualenv.

Although the pip and virtualenv command-line tools will be installed, the recommended way to invoke them is as modules to ensure that the expected version is used:

$ python3 -m pip install <package>
$ python3 -m venv <dir>

The role currently assumes that the user's login shell is bash and modifies startup files accordingly.

By default, Python is installed from packages. If the python3_pyenv variable is set, pyenv will be installed and then used to install the requested Python version, from source if necessary. A pyenv install is only visible for the current Ansible user (the login user by default). The role will not activate the new Python; see the pyenv documentation for ways to do this.

This role is also available on Ansible Galaxy.
