Install: 'inappropriate ioctl for device' when running install.sh

Symptoms

• While installing with the one-liner, you see repeated:
  • inappropriate ioctl for device
• The install may still continue, but can fail later (sometimes with a misleading retry like npm install openclaw@latest failed; retrying openclaw@next).
• This is most common when piping the script into sudo bash.

Cause

The installer is doing interactive / TTY-oriented work (terminal state changes + UI via gum). When you run curl ... | sudo bash, stdin often isn’t a real TTY, so those steps print inappropriate ioctl for device.

Fix

1) Run the installer with a real TTY (recommended)

Download the script, then run it normally (interactive shell):

curl -fsSL https://openclaw.ai/install.sh -o /tmp/openclaw-install.sh
bash /tmp/openclaw-install.sh

2) Disable gum UI

curl -fsSL https://openclaw.ai/install.sh | bash -s -- --no-gum

3) If Node is already installed, install via npm directly

npm i -g openclaw@latest
openclaw onboard --install-daemon

Verify

openclaw version
openclaw gateway status

If the installer still fails, capture the lines after the first WARN npm install ... failed message (the ioctl lines are often just noise).
