Django命令抛出TypeError : handle() got an unexpected keyword argument

Question

我正在使用Django 1.10.4和Python 3.52。当我尝试通过python manage.py my_command运行Django命令时，出现以下错误:

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)
  File "path_to_envs/envs/env_name/lib/python3.5/site-packages/django/core/management/__init__.py", line 367, in execute_from_command_line
    utility.execute()
  File "path_to_envs/envs/env_name/lib/python3.5/site-packages/django/core/management/__init__.py", line 359, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)
  File "path_to_envs/envs/env_name/lib/python3.5/site-packages/django/core/management/base.py", line 294, in run_from_argv
    self.execute(*args, **cmd_options)
  File "path_to_envs/envs/env_name/lib/python3.5/site-packages/django/core/management/base.py", line 345, in execute
    output = self.handle(*args, **options)
TypeError: handle() got an unexpected keyword argument 'verbosity'

我可以运行本地django服务器并与管理页面进行交互。包含该命令的应用程序位于我的 settings.py文件中。

以下是django命令的内容:

from django.core.management import BaseCommand
from my_module import MyClass


class Command(BaseCommand):
    def handle(self):
        my_class = MyClass()
        my_class.my_method()

在发生错误时， options字典包含 {'verbosity': 1, 'no_color': False, 'settings': None, 'pythonpath': None, 'traceback': False}。根据字典 no_color， traceback和其他字典的随机顺序，它们将抛出相同的 TypeError。经过一天的搜索，我仍然无法弄清楚问题出在哪里。有没有人见过这个？

经过大量谷歌搜索并拔掉头发后，问题出在handle()的参数个数不正确。

这:

    def handle(self):

应该:

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