我在subprocess.run上发现错误了吗？

Question

我有以下程序

import os
import sys
import subprocess
from pathlib import Path

program = subprocess.check_output("which gphotos-sync", shell=True).decode().strip()

home = Path(os.path.expanduser("~")) / "photos"

args = [
  "--ntfs",
  "--retry-download",
  "--skip-albums",
  "--photos-path ".",
  "--log-level", "DEBUG",
]

env = os.environ.copy()
env["LC_ALL"] = "en_US.UTF-8"

for p in home.glob("*/*"):
  print([program, *args, str(p.relative_to(home))])
  subprocess.run([program, *args, str(p.relative_to(home))], cwd=home, shell=True, env=env, stdout=sys.stdout, stderr=subprocess.STDOUT)

哪张照片

['/home/ubuntu/.local/bin/gphotos-sync', '--ntfs', '--retry-download', '--skip-albums', '--photos-path .', '--log-level DEBUG', 'rodrigo/0']
usage: gphotos-sync [-h] [--album ALBUM] [--log-level LOG_LEVEL] [--logfile LOGFILE] [--compare-folder COMPARE_FOLDER] [--favourites-only] [--flush-index] [--rescan] [--retry-download]

                    [--ntfs]
                    root_folder

如您所见，gphotos-sync需要root_folder（最后一个参数）。但是，如果我手动运行打印的命令行，程序工作正常

/home/ubuntu/.local/bin/gphotos-sync --ntfs --retry-download --skip-albums --photos-path . --log-level DEBUG rodrigo/0

我错过什么了吗

当一个选项接受一个参数时，它们要么是单独的参数，要么必须使用 option=parameter语法。不能将它们放在同一个参数中，用空格分隔

因此，它应该是：

args = [
  " ntfs",
  " retry-download",
  " skip-albums",
  " photos-path", ".",
  " log-level", "DEBUG",
]
