这是我第一次使用django rest和Django Oauth工具包我正在遵循本教程 oauth2-with-django-rest-framework 但是当我运行python manage.py migrate时,我收到以下错误:

ImportError:无法为API设置'DEFAULT_AUTHENTICATION_CLASSES'导入'oauth2_provider.ext.rest_framework.OAuth2Authentication'.ImportError:没有名为ext.rest_framework的模块.

出了什么问题？我应该安装另一个模块吗？我的虚拟环境包含:

CERTIFI == 2017年4月17日

chardet的== 3.0.4

Django的== 1.11.2

Django的扩展== 1.8.1

Django的OAuth的工具== 1.0.0

djangorestframework == 3.6.3

IDNA == 2.5

oauthlib == 2.0.2

pytz == 2017.2

请求== 2.18.1

6 == 1.10.0

Unidecode == 0.4.21

urllib3 == 1.21.1

这是我第一次使用 celery，我浏览了本教程：将 celery 与 Django 一起使用，
但是当我运行代码时，它给了我以下错误：

from celery import Celery
ImportError: cannot import name Celery

怎么了 ？
谢谢

我必须对react-big-calendar模块进行一些更改，因此我在github上创建了该项目，进行了修改并推送。然后，我使用以下命令来安装新软件包：

npm install https://github.com/wafa-yahyaoui/react-big-calendar/tarball/master --save

该软件包在package.json的依赖项中指出：

有没有办法在多个键上加入clojure集？例如,我有set1和set2.我想加入基于键的键:a和:b

(def set1 #{ {:a 1 :b 2 :c 3} {:a 3 :b 4 :c 5} }) (def set2 #{ {:a 1 :b 2 :d 4} {:a 3 :b 4 :d 6} {:a 7 :b 7} {:a 1 :b 2 :c 4}})

期望的输出是

#{{:a 1 :b 2 :c 3 :d 4} {:a 1 :b 2 :c 4} {:a 3 :b 4 :c 5 :d 6} }
