OperationalError: attempt to write a readonly database
解決辦法：
1.通過django項目的settings.py可以看到關聯數據庫文件名稱
...
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
...
2.將django項目中的數據庫文件(db.sqlite3)和數據庫文件所在文件夾提升權限
chmod 777 db.sqlite3
cd ..
chmod 777 *
3.再次訪問數據庫就沒問題啦 啦啦啦
