Claude Code One-Click Install Script

If you've already purchased quota, you can use the one-click script directly. Just change API_KEY in the script to your own key and run it.

Usage

chmod +x claudecode.sh
./claudecode.sh

Usage Notes

The script automatically installs dependencies like Node.js, jq, and Python3, and creates or overwrites ~/.claude/settings.json (back up your existing configuration first). The written ANTHROPIC_BASE_URL is https://api.nexthub.cc without a /v1 suffix. On Linux, if a global install hits a permission error (EACCES), the script automatically retries with sudo.
