Installing the Claude CLI means downloading the program and putting it somewhere your terminal can find it. There are two ways to do it. For most people new to this, one is clearly easier.
The native installer (recommended)
One command. It downloads the CLI and sets it up, with nothing to install first:
curl -fsSL https://claude.ai/install.sh | bash
That line looks like a lot. Read it the way you read commands in the
terminal chapter: curl is a command that downloads something, the
web address is what it downloads (the official Anthropic install
script), and | bash runs that script. It's the install button, typed.
Use this one. It's the shortest path and it doesn't ask you to set anything up beforehand.
The npm way (if you already have Node)
The other way uses npm, a catalog of JavaScript programs. npm comes bundled with Node.js — the program that runs JavaScript outside a browser. If you're already a Node user, this works:
npm install -g @anthropic-ai/claude-code@latest
Read that line:
npm install -g @anthropic-ai/claude-code@latest
↑ npm ↑ -g = for the whole machine, so `claude` works in any folder
If you don't know what Node is, you don't have it, and that's fine. Don't install Node just for this. The native installer above skips it entirely. The npm route only earns its place once Node is already part of your world, which it will be later in the course if you go the developer direction.
Which to use
If you're following along on a Mac or Linux machine: use the native
installer, the curl line. On Windows, the native installer works
inside the terminal you set up last chapter as well. One command, no
prerequisites. The next step runs it.
