This week was not only the release of macOS Monterey, but it was also new Mac Book Pro week for a lot of people, including myself. Given that it was alot of effot to install Python on macOS Big Sur I was a little worried that it would take the same amount of effort.

As I was starting a with a clean macOS Monterey installation and had already installed Homebew↗ I just needed to run the following command to install pyenv↗:

Install pyenv
``` terminfo
brew install pyenv
Once installed, I ran the following to download and compile Python 3.10.0:




```bash frame="terminal" title="Install Python 3.10.0 using pyenv"
``` terminfo
pyenv install 3.10.0
pyenv global 3.10.0
pyenv version
The last command should return something similar to the following output:


```bash frame="terminal" title="Output of the command"
$ pyenv version
3.10.0 (set by /Users/russ.mckendrick/.pyenv/version)

Now that Python is installed and we have set version 3.10.0 to the default Python install used by pyenv, we need to run the following command to ensure that our preferred version is used whenever we open a new terminal session.

Make sure the pyenv version is used
``` terminfo
echo -e $'if command -v pyenv 1>/dev/null 2>&1; then\\n  export PYENV_ROOT="$HOME/.pyenv"\\n  export PATH="$PYENV_ROOT/bin:$PATH"\\n  eval "$(pyenv init --path)"\\n  eval "$(pyenv init -)"\\nfi' >> ~/.zshrc
Open a new shell and run:


```bash frame="terminal" title="Check the python version"
``` terminfo
python --version
which python
```bash frame="terminal" title="Output of the command"
$ python --version
Python 3.10.0
$ which python
/Users/russ.mckendrick/.pyenv/shims/python

The final step is to make sure that pip is up-to-date, to do this run:

Update pip
``` terminfo
pip install --upgrade pip
```bash frame="terminal" title="Install Ansible"
``` terminfo
pip install --user ansible
ansible --version
As you can see from the output below, Ansible was isntalled and using the correct version of Python:


```bash frame="terminal" title="Output of the command"
$ ansible --version
ansible [core 2.11.6]
  config file = None
  configured module search path = ['/Users/russ.mckendrick/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /Users/russ.mckendrick/.local/lib/python3.10/site-packages/ansible
  ansible collection location = /Users/russ.mckendrick/.ansible/collections:/usr/share/ansible/collections
  executable location = /Users/russ.mckendrick/.local/bin/ansible
  python version = 3.10.0 (default, Oct 26 2021, 20:43:52) [Clang 13.0.0 (clang-1300.0.29.3)]
  jinja version = 3.0.2
  libyaml = True

This was a massive improvement on last years experience as it was far from smooth on day one, so props to pyenv and Homebrew teams 👍
