What's Wrong?

Environment

• OS: Windows 11
• Claude Code version: 2.0.76
• Node.js: v24.x (Windows), v24.11.0 (WSL)
• Installation: npm global

Problem

Claude Code exits silently without any output on Windows PowerShell.
Running claude, claude -p "hello", or claude --dangerously-skip-permissions all exit immediately with no response.

Debug log shows:

spawn-rx Failed to find executable anywhere in path

(repeated 18 times)

What I tried:

• Added Git, ripgrep, fd to PATH
• Reinstalled Claude Code
• Different versions (2.0.76, 2.0.50)

Workaround:

Works perfectly in WSL (Ubuntu). Same machine, same project folder.

Expected behavior:

Claude Code should work on Windows as documented.
