Python 属性错误：模块'；app.management.commands.api'；没有属性'；命令'；

我有一个从API（英国公司）获取信息的文件。为了测试我

import requests

r = requests.get('https://api.companieshouse.gov.uk/company/00002065', auth=('xxxxx', ''))
print(r.text)

它工作并生成数据，但在数据之后，我得到以下错误消息

AttributeError:模块“app.management.commands.api”没有属性 “命令”

这是为什么？我如何解决

编辑-此外，如果我在文件所在的同一文件夹中运行“py ch_api.py”，则不会出错；只有在运行“py manage.py ch_scrape”时，我才会得到错误（我需要通过第二种方法运行它）

编辑2-更多信息

好的，明白了。来自Rails，我不确定需要什么或为什么命令（BaseCommand），但我会边学边用。如果有人想稍微推动一下这一切，我们将不胜感激

from django.core.management.base import BaseCommand, CommandError
import requests

class Command(BaseCommand):
    def handle(self, *args, **options):

        r = requests.get('https://api.companieshouse.gov.uk/company/00002065', auth=('DKvKM78qjU0Er_PGYnAdfSpgNquuz9LA_GYp1KNY', ''))
        print(r.text)

这里没有足够的信息来帮助您解决此问题-请发布代码，以便有人重现此问题。错误消息表明您的管理命令文件缺少

command

类，这是Django在运行管理命令时查找的。这是文件中的全部代码-我已添加了我的文件夹和文件（如果有帮助）以及“manage.py”和“settings.py”文件，但是，这只是一个新的Django项目，具有“获取”应用程序在管理>命令中添加API文件。如果有人需要任何进一步的信息，请告诉我。同样，实际的函数工作正常，但以我需要修复的错误结束。此外，如果我运行py ch_API.py，它将正常工作；只有当我运行py manage.py ch_scrape时，我才会得到错误（我需要通过第二种方法运行它）建议您阅读有关如何编写管理命令的文档：

from django.core.management.base import BaseCommand, CommandError
import requests

class Command(BaseCommand):
    def handle(self, *args, **options):

        r = requests.get('https://api.companieshouse.gov.uk/company/00002065', auth=('DKvKM78qjU0Er_PGYnAdfSpgNquuz9LA_GYp1KNY', ''))
