[Django Django project stepped pit] run error "No installed app with label 'admin'." Several solutions

When you run the Django project, the error "No installed app with label 'admin'."

Environmental roughly as follows:

Python version 3.5

Django version 2.2

Mysql database

admin application is registered, but still an error.

 

Option 1: online information that is Django2.2 a bug (do not know is not), the method provides a fall back to the old version of Django.

(Version always updated, could not have been guarding the old version, not recommended )

pip install django==2.1.8

 

Option 2 For mysqlclient , pymysql or sqlparse  updated : Recommended use mysqlclient

 pip install mysqlclient

mysqlclient compatible django2.2, and pymysql not necessarily compatible (test the latest version is useless). If you can not install or uninstall pymysql legacy.

 

Note : Please configured correctly when localization settings, or will report an error

LANGUAGE_CODE = 'zh-hans'

TIME_ZONE = 'Asia/Shanghai'

 

If not resolved , see if it is apps.py an application in the name of an attribute is not set up correctly (pycharm project will create apps.py)

from django.apps import AppConfig


# 这是对应应用booktest
class BooktestConfig(AppConfig):
    name = 'booktest'
