我尝试通过 Popen 和 subprocess.check_call 从 python 运行 rsync，得到了同样的错误：

subprocess.check_call(['rsync', '-au', '/opt/catflow/EpressCatalog/*', '/Users/pistacchio/dev/epress/catflow/portal/branches/noscript/frontend/static/repo/usr/2/catalogs/2/builds/ipad'])
rsync: link_stat "/opt/catflow/EpressCatalog/*" failed: No such file or directory (2)
rsync error: some files could not be transferred (code 23) at /SourceCache/rsync/rsync-42/rsync/main.c(992) [sender=2.6.9]
*** CalledProcessError: Command '['rsync', '-au', '/opt/catflow/EpressCatalog/*', '/Users/pistacchio/dev/epress/catflow/portal/branches/noscript/frontend/static/repo/usr/2/catalogs/2/builds/ipad']' returned non-zero exit status 23

似乎问题在于它找不到（或访问）/opt/catflow/EpressCatalog/*。它不仅存在，而且从命令行运行它会给出正确的结果。

有什么帮助吗？

该subprocess模块自己处理参数的引用。当一个参数条目中有空格时，默认情况下会引用它。

简化示例：

['-input', 'eggs.txt', '-output', 'spam spam.txt']

在外壳上被称为

-input eggs.txt -output "spam spam.txt"

安全注意事项：切勿使用shell=True。它打开了外壳注入攻击的风险。有关详细信息，请参阅官方文档。
