If you had chosen a Python 2 version of Anaconda, you should get a similar output to the one below. You can type the command below in your terminal to open a Jupyter Notebook. Now let's take a moment to install PyEnv. This library will help you switch between different versions of Python in case you need to run Python 2. Note that you can substitute 3. For example, once Python 4.
If you encounter an error that "C compiler cannot create executables" then the simplest way to solve this is to reinstall Apple's Xcode.

When choosing a control node, remember that any management system benefits from being run near the machines being managed. If you are using Ansible to manage machines in a cloud, consider using a machine inside that cloud as your control node.
In most cases Ansible will perform better from a machine on the cloud than from a machine on the open Internet. Ansible 2. Starting with Ansible 2.
Although you do not need a daemon on your managed nodes, you do need a way for Ansible to communicate with them. For any machine or device that can run Python, you also need Python 2 version 2. These requirements should be listed in the module documentation. You can use the yum module or dnf module in Ansible to install this package on remote systems that do not have it. By default, before the first Python module in a playbook runs on a host, Ansible attempts to discover a suitable Python interpreter on that host.
See Interpreter Discovery for details. Technically, you can use Ansible to install a compatible version of Python using the raw module , which then allows you to use everything else.

It contains the Ansible language, runtime, and a short list of core modules and other plugins. You can build functionality on top of ansible-core by installing collections from Galaxy, Automation Hub, or any other source. Install ansible-core version 2. You should only run ansible-core from devel if you are modifying ansible-core , or trying out features under development. This is a rapidly changing source of code and can become unstable at any point.
