OperationalError: attempt to write a readonly database

解决办法：

1.通过django项目的settings.py可以看到关联数据库文件名称

...

DATABASES = {

'default': {

'ENGINE': 'django.db.backends.sqlite3',

'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),

}

}

...

2.将django项目中的数据库文件(db.sqlite3)和数据库文件所在文件夹提升权限

chmod 777 db.sqlite3

cd ..

chmod 777 *

3.再次访问数据库就没问题啦 啦啦啦
