来自documentation

You can customize the instance by overriding this method and calling super() with kwargs of ArgumentParser parameters.

通过覆盖 create_parser 方法 您可以设置 ArgumentParser 的 formatter_class:

from argparse import RawTextHelpFormatter
from django.core.management.base import BaseCommand


class Command(BaseCommand):
    def create_parser(self, *args, **kwargs):
        parser = super(Command, self).create_parser(*args, **kwargs)
        parser.formatter_class = RawTextHelpFormatter
        return parser
