I have a python script which runs as part of yarn build for my static-site project deployed to Vercel. The script uses rsync to do some file copying, using os.system to make the call to rsync from within the python script: os.system(f"rsync -a {full_path} dest_path"). This works great locally, however when I try to deploy to Vercel I get the error: sh: line 1: rsync: command not found I tried a few other approaches as well: using subprocess.run(["npx", "rsync", "-a", full_path, dest_path], check=True) to try get npx to run the command. Vercel build error: npm error could not determine executable to run Tried adding rsync to my developer dependencies in package.json and retrying. Finally I also tried using rsync_path = subprocess.check_output(["which", "rsync"]).decode("utf-8").strip() subprocess.run([rsync_path, "-a", full_path, dest_path], check=True) Vercel build error: error Command failed with exit code 1. Is there a simple way for me to use rsync during my Vercel deployment? Does it even exist on the deployment machine? If not how can I set it up to use rsync? Continue reading...
