我无法在django 2.2.5中运行导入导出功能

我想在Django管理面板数据导入和导出中导入导出选项

另外，请尝试使用此示例

设置.py

 INSTALLED_APPS = [
        'django.contrib.admin',
        'django.contrib.auth',
        'django.contrib.contenttypes',
        'django.contrib.sessions',
        'django.contrib.messages',
        'django.contrib.staticfiles',
        'import_export',
        'app',


    ]

resource.py

管理员

所有应用程序模块数据导入和导出都需要完美工作。

请尝试此代码

from django.contrib import admin
from .models import Person    # 

from import_export import resources

from import_export.admin import ImportExportModelAdmin

class PersonAdmin(ImportExportModelAdmin):   # FOR ADMIN IMPORT EXPORT ONLY 
    pass


admin.site.register(Person, PersonAdmin)   #  FOR ADMIN IMPORT EXPORT ONLY 

设置.py

 INSTALLED_APPS = [
        'django.contrib.admin',
        'django.contrib.auth',
        'django.contrib.contenttypes',
        'django.contrib.sessions',
        'django.contrib.messages',
        'django.contrib.staticfiles',
        'import_export',
        'app',


    ]

请格式化您的代码以正确显示。您究竟是如何无法运行此操作的？它是否完全无法运行，是否抛出错误，是否无法产生异常影响？**从代码中看，所有内容都是正确的**`RemovedIndjangO30警告位于/admin/accounts/person/import/{%load admin\u static%}不赞成使用{%load static%}。Django版本：2.2.5异常类型：RemovedIndjango30警告异常值：{%load admin_static%}已被弃用，取而代之的是{%load static%}。{%load admin_static%}被弃用，取而代之的是{%load static%}`请发布完整细节的问题。**仍然不起作用，我认为包和python版本存在问题
