Question: How do I install Claude Code version 2.1.77?

Answer:

Installing Claude Code v2.1.77

There are two main approaches depending on your installation method.

Method 1: Native Installer (Recommended) — Install a Specific Version

To install a specific version using the native installer, pass the version number as an argument to the install script:

macOS / Linux:

curl -fsSL https://claude.ai/install.sh | bash -s 2.1.77

Windows (PowerShell):

irm https://claude.ai/install.ps1 | iex

Note: The Windows PowerShell method installs the latest by default. For a specific version on Windows, use WSL and run the Linux command above inside it.

Method 2: npm (Legacy) — Install a Specific Version

The npm method still works but is no longer the recommended approach. Use this if you need to pin a specific version or work in an environment where npm is the standard package manager.

npm install -g @anthropic-ai/claude-code@2.1.77

Note: This requires Node.js 18.0+. If you see EACCES permission errors, do not use sudo. Fix your npm permissions instead.

Method 3: Pin the Version and Disable Auto-Updates

After installation, if you want to stay on 2.1.77 and prevent auto-updates:

Set DISABLE_AUTOUPDATER to "1" in the env key of your settings.json file to prevent automatic updates after pinning a version.

Your ~/.claude/settings.json should look like:

{
  "env": {
    "DISABLE_AUTOUPDATER": "1"
  }
}

Verify the Installation

claude --version

You should see 2.1.77 confirmed in the output.

Important Notes

The native installer is faster, requires no dependencies, and auto-updates in the background. Use the native installation method when possible.
Claude Code requires a paid account — Claude Pro ($20/month) works for most developers. If you only need API access, an Anthropic Console account with credits works too.
