What's Wrong?

FreeBSD x64 support broken after recent update

Problem

Claude Code used to work on FreeBSD x64 but a recent update broke it. The postinstall script now exits with:

[@anthropic-ai/claude-code postinstall] Unsupported platform: freebsd x64
Supported: darwin-arm64, darwin-x64, linux-x64, linux-arm64, linux-x64-musl, linux-arm64-musl, win32-x64, win32-arm64

Version 2.1.112 was the last one working correctly on FreeBSD x64.

Request

Please either add FreeBSD as a supported platform (a linux-x64 binary works via FreeBSD's Linux compatibility layer), or restore the Node.js fallback for unsupported platforms that existed before this regression.

What Should Happen?

Expected behavior

Either:

1. FreeBSD x64 is added to the supported platforms list, or
2. A fallback to the pure Node.js entrypoint is available when no native binary exists (as it was up to version 2.1.112)

Workaround

Pinning to the last working version:

npm install -g @anthropic-ai/claude-code@2.1.112

Or running the Node.js entrypoint directly:

node /usr/local/lib/node_modules/@anthropic-ai/claude-code/cli.js

Steps to Reproduce

Environment

• OS: FreeBSD x64
