def main(): """Run administrative tasks.""" os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'weixin_stampingHub.settings') try: from django.core.management import execute_from_command_line except ImportError as exc: raise ImportError( "Couldn't import Django.

根据您提供的代码段，问题出现在 `.py` 文件的第 17 行。根据错误提示 `SyntaxError: invalid syntax`，这可能是由于该行代码的语法错误导致的。

在第 16 行的 `raise ImportError(...)` 语句之后，您缺少了一个换行符或缩进，导致语法错误。请尝试将第 17 行修改为如下形式：

        ) from exc

修改后的代码如下所示：

def main():
    """Run administrative tasks."""
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'weixin_stampingHub.settings')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)

请尝试重新运行命令，看看是否解决了问题。如果问题仍然存在，请提供 `manage.py` 文件的其他相关代码段，以便我能够更详细地帮助您解决这个问题。
