All of this takes place command line, so launch the Terminal window.
If you don't have X-code installed this installs the command line part, which is massively smaller than the full X-code:
xcode-select --install- Click Install
- Wait until it says "command line tools installed"
Homebrew is the 'missing software package manager' for MacOS. You can easily install and upgrade software packages for development tools and other open-source stuff.
The magic installation incantation is:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
You have to enter your user account password, and then hit RETURN part way through to proceed.
You then follow the instructions to finish the installation, which look something like this...
echo >> ~/.zprofile
echo 'eval "$(/usr/local/bin/brew shellenv)"' >> ~/.zprofile
eval "$(/usr/local/bin/brew shellenv)"
It is possible to install Node using Homebrew, but I often have problems so prefer to use the official Node installer. Brew sometimes installs unstable versions, so another reason to use this approach (NVM).
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash
. ~/.nvm/nvm.sh
This says to install Node version 22:
nvm install 22
Maybe you already have Python installed? MacOS X-code insists in installing something old, 3.9? You can check with...
python3 --version
If it's older than 3.12, install Python 3.12...
brew install python@3.12
This can be installed using Brew:
brew install pulumi
