Git Bash에서 Codex 실행 오류 해결

발생한 에러

$ codex
Error: spawn C:\Users\[user]\AppData\Roaming\npm\node_modules\@openai\codex\bin\codex-x86_64-pc-windows-msvc.exe ENOENT
    at ChildProcess._handle.onexit (node:internal/child_process:286:19)
    at onErrorNT (node:internal/child_process:484:16)
    at process.processTicksAndRejections (node:internal/process/task_queues:82:21) {
  errno: -4058,
  code: 'ENOENT',
  syscall: 'spawn C:\\Users\\[user]\\AppData\\Roaming\\npm\\node_modules\\@openai\\codex\\bin\\codex-x86_64-pc-windows-msvc.exe',
  path: 'C:\\Users\\[user]\\AppData\\Roaming\\npm\\node_modules\\@openai\\codex\\bin\\codex-x86_64-pc-windows-msvc.exe',
  spawnargs: []
}

원인

Git Bash는 Windows 실행기(codex.cmd)를 직접 못 불러옴 → ENOENT 발생

해결 방법

~/.bashrc에 alias 추가:

alias codex="winpty codex.cmd"

적용:

source ~/.bashrc

→ Git Bash에서도 codex 실행 가능
