Fixing cron's missing image snap tool | Generated by AI
The latest cron run is failing. Here’s the summary:
Error: FileNotFoundError: [Errno 2] No such file or directory: 'imagesnap'
Root cause: The cron environment has a minimal PATH (/usr/bin:/bin), but imagesnap is a Homebrew tool at /opt/homebrew/bin/. The ww binary itself is found because the cron line uses its full path /opt/homebrew/bin/ww, but when appearance smart-auto internally calls subprocess.run(["imagesnap", ...]), it can’t find it.
The cron mail at 17:24:42 shows the full traceback. Every 2-minute run is hitting this.
Quick fix — either:
- Add PATH to your crontab:
PATH=/opt/homebrew/bin:/usr/bin:/bin
*/2 * * * * /opt/homebrew/bin/ww appearance smart-auto
- Or symlink imagesnap into a cron-visible path:
sudo ln -sf /opt/homebrew/bin/imagesnap /usr/local/bin/imagesnap
Option 1 is cleaner. Want me to update your crontab?
