Ansible role for installing Python 3.

python3

This Ansible role will install Python 3 and the pip and virtualenv utilities. The new version of Python is installed independently of the existing system Python installation.

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:

$ python3.6 -m pip install <package>
$ python3.6 -m venv <dir>

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. The role will not activate the new Python; see the pyenv documentation for ways to do this.

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

This role is also available on Ansible Galaxy.

Role Variables

• python3_command: Python command name
• python3_bashrc: login file to modify; defaults to bash_profile
• python3_local: local binary directory; system-dependent
• python3_pyenv: Python version to install using pyenv
