Как подключиться к MySQL db из python 3 16.04

Question 1

Я следую этому руководству, чтобы я мог установить коннектор MySQL для Python 3.

К сожалению, когда я набрал:

(env) pip install mysqlclient

Не могли бы вы посоветовать.

Question 2

Вам нужны библиотеки разработки python для сборки модулей python:

sudo apt install python3-dev libpython3-dev

должен позаботиться об этом за вас.

Но рекомендуемый способ добавить это в Ubuntu - использовать репозитории Ubuntu. Таким образом, чтобы установить привязки mysql для python3, запустите

sudo apt install python3-mysqldb

. Это установит привязки, необходимые для подключения к mysql из Python 3, и гарантирует, что он будет обновлен вместе с другими пакетами вашей системы. Это рекомендуется, если вам специально не нужна более новая версия или пакет недоступен в репозиториях Ubuntu.

Question 3

Question 4

MySQLdb dia tsy miara-miasa amin'ny Python 3. raha azo atao ny mivadika amin'ny MySQLdb dia manoro hevitra anao aho hampiasa MySQL mpampitohy Python . Satria miasa amin'ny Python 2 sy 3 izy roa ary mpamily Oracle ofisialy MySQL miasa miaraka amin'i Python.

pip install mysql-connector-python

raha tsy mahomby ny pip dia azonao atao ny misintona ny installer avy amin'ny https: //dev.mysql .com / alaina / connector / Python /

izany hoe fametrahana MySQL Connector mampiasa fonosana DEB Jereo ity toro-lalana ity mba hisintomana sy hametrahana

Ity modely ity dia manaraka ny Python Database API Specification v2.0 (PEP 249).

Avy eo ampiasao fomba fampifandraisana () ny python mpampitohy MySQL hifandray amin'ny MySQL.mampita ny fomba fiadian-kevitra ilaina hampifandraisina (). izany hoe Host, solonanarana, tenimiafina ary anarana database
