class Command(BaseCommand):
    help = 'Renames a Django project'

    def add_arguments(self, parser):
        parser.add_argument('current', type=str, nargs='+',
                            help='The current Django project folder name')
        parser.add_argument('new', type=str, nargs='+',

    def handle(self, *args, **kwargs):

        new_project_name = kwargs['new'][0]

        # logic for renaming the files

        files_to_rename = [f'{current_project_name}/settings/base.py',

        for f in files_to_rename:
            with open(f, 'r') as file:
                filedata = file.read()

            filedata = filedata.replace(current_project_name, new_project_name)

            with open(f, 'w') as file:
                file.write(filedata)

        os.rename(current_project_name, new_project_name)

        self.stdout.write(self.style.SUCCESS(
            'Project has been renamed to %s' % new_project_name))

Answer 1

我有同样的错误。
在视频教程中，进行了一些不同的代码

更改

files_to_rename = [f'{current_project_name}/settings/base.py',
                           f'{current_project_name}/wsgi.py', 'manage.py']

以

files_to_rename = [f'demo'/settings.py', f'demo'/wsgi.py', 'manage.py']

添加

folder_to_rename = 'demo'

更改

filedata = filedata.replace(current_project_name, new_project_name)

调用

 filedata = filedata.replace('demo', new_project_name)

并

python manage.py rename demo programname

Answer 2

您可能使用的是Django的最新版本，而不是视频。在这种情况下，您需要键入（在视频中使用值）：

python manage.py rename demo djecommerce

重命名命令现在需要旧的foldername和新名称。
