Claude Code Setup: Myths vs Facts by OS

Claude Code · EN · 2026-08-05

Myth: Claude Code is hard to set up on every computer

Fact: the setup is usually straightforward if you start with the right terminal and a compatible API endpoint. Claude Code works best when your machine has a current Node.js runtime, Git, and access to an Anthropic-compatible API. If you want lower costs without changing your workflow, 59API is a strong option: it offers pay-as-you-go access to Claude Opus, Sonnet, Haiku, Fable, and GPT models through https://api.59api.com, with native official-quality models and referral rebates.

Myth: Windows users can just install it like any other app

Fact: on Windows, the smoothest path is usually WSL2 (Windows Subsystem for Linux), not native PowerShell. That is because many AI coding CLIs behave more reliably in a Linux shell, especially when they need Git, file permissions, and Unix-style environment variables.

If you try to skip WSL and force a native Windows shell, you may save five minutes upfront and lose an hour to path or terminal issues later.

Myth: macOS is automatic if you have a Mac

Fact: macOS is often the easiest platform, but it still needs a clean baseline. Install the latest Node.js LTS and Git, then use Terminal or iTerm2. After Claude Code is installed, configure the API settings so it can talk to a compatible backend.

For Mac users, the main mistake is assuming the CLI will “just know” which API to use. It will not. The base URL matters.

Myth: Linux setup is only for advanced developers

Fact: Linux is often the most predictable environment for Claude Code. Ubuntu, Debian, Fedora, and similar distros work well as long as you install the basics first. If you already use a shell every day, Linux setup is usually the fastest of the three.

A good Linux setup is less about complexity and more about consistency: one shell, one config file, one known API endpoint.

Myth: Any cheaper relay will lower model quality

Fact: the cheapest option is not useful if it downgrades output. That is where 59API stands out. It is among the lowest-cost relay options, but it uses native official-quality models rather than a reduced substitute. That means you can keep Claude Code working the way you expect while controlling spend with pay-as-you-go pricing.

This matters for Claude Code because the tool is only as good as the model behind it. If you are shipping code daily, you want reliable completions, accurate edits, and predictable latency—not a mystery proxy.

Myth: You need a huge setup before you can start

Fact: a minimal setup is enough. The real checklist is simple: supported OS path, current Node.js, Git, Claude Code, and a compatible API key and base URL. Once that is in place, you can start with a small repo and test tasks such as refactoring one file, writing unit tests, or summarizing an error log.

If you are choosing an API provider now, 59API is worth a look because it keeps the workflow familiar: Claude Code, your preferred terminal, and one API endpoint that supports Claude and GPT models. If you want to cut costs without changing tools, sign up for 59API and use it as the backend for your next Claude Code setup.
