python-3.x - 如何让 plumbum.local 在你的 Windows 系统上运行

Question

在我的 django 应用程序中，我通过从环境变量中获取参数来创建数据库，但它会引发以下错误。

    createdb = plumbum.local["createdb"]
  File "C:\Users\xyz\lib\site-packages\plumbum\machines\local.py", line 249, in __getitem__
    return LocalCommand(self.which(cmd))
  File "C:\Users\C:\Users\xyz\lib\site-packages\plumbum\machines\local.py", line 211, in which
    raise CommandNotFound(progname, list(cls.env.path))
plumbum.commands.processes.CommandNotFound: ('createdb')

我创建 postgres 数据库的代码：

import plumbum
def create_db():
    from myapp import settings

    createdb = plumbum.local["createdb"]
    for db_name, db_info in settings.DATABASES.items():
        createdb["-h", db_info.get("HOST"), "-p", db_info.get("PORT"), db_info.get("NAME")].run(
            retcode=[0, 1]
        )

如何让它在windows上工作？
