1.安装requirements.txt依赖包（环境）
pip install -r requirements.txt

2.修改settings.py下的数据库配置
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        # 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
        'NAME': 'lms',
        'HOST': '127.0.0.1',
        'PORT': '3306',
        'USER': 'root',
        'PASSWORD': 'root'
    }
}

3.导入数据库文件lms.sql

python manage.py makemigrations
python manage.py migrate
#上面两步进行迁移，完成数据库表的建立


4.命令行输入
python manage.py runserver
#默认端口开在127.0.0.1:8000


PS：#创建超级管理员用户
python manage.py createsuperuser

5.然后浏览器打开localhost:8080/127.0.0.1:8000/进入管理系统

query = query.decode(errors='replace')
AttributeError: 'str' object has no attribute 'decode'

def last_executed_query(self, cursor, sql, params):
    # With MySQLdb, cursor objects have an (undocumented) "_executed"
    # attribute where the exact query sent to the database is saved.
    # See MySQLdb/cursors.py in the source distribution.
    query = getattr(cursor, '_executed', None)
    if query is not None:
        query = query.decode(errors='replace')
    return query
