This project is a fork of MySQLdb1. This project adds Python 3 support and fixed many bugs.

When your question looks relating to Python rather than MySQL:

Or when you have question about MySQL:

Building mysqlclient on Windows is very hard. But there are some binary wheels you can install easily.

If binary wheels do not exist for your version of Python, it may be possible to build from source, but if this does not work, do not come asking for support. To build from source, download the MariaDB C Connector and install it. It must be installed in the default location (usually «C:\Program Files\MariaDB\MariaDB Connector C» or «C:\Program Files (x86)\MariaDB\MariaDB Connector C» for 32-bit). If you build the connector yourself or install it in a different location, set the environment variable MYSQLCLIENT_CONNECTOR before installing. Once you have the connector installed and an appropriate version of Visual Studio for your version of Python:

Install MySQL and mysqlclient:

# Assume you are activating Python 3 venv $ brew install mysql pkg-config $ pip install mysqlclient 

If you don’t want to install MySQL server, you can use mysql-client instead:

# Assume you are activating Python 3 venv $ brew install mysql-client pkg-config $ export PKG_CONFIG_PATH="/opt/homebrew/opt/mysql-client/lib/pkgconfig" $ pip install mysqlclient 

Note that this is a basic step. I can not support complete step for build for all environment. If you can see some error, you should fix it by yourself, or ask for support in some user forum. Don’t file a issue on the issue tracker.

You may need to install the Python 3 and MySQL development headers and libraries like so:

• $ sudo apt-get install python3-dev default-libmysqlclient-dev build-essential pkg-config # Debian / Ubuntu
• % sudo yum install python3-devel mysql-devel pkgconfig # Red Hat / CentOS

Then you can install mysqlclient via pip now:

mysqlclient uses pkg-config —cflags —ldflags mysqlclient by default for finding compiler/linker flags.

You can use MYSQLCLIENT_CFLAGS and MYSQLCLIENT_LDFLAGS environment variables to customize compiler/linker options.

$ export MYSQLCLIENT_CFLAGS=`pkg-config mysqlclient --cflags` $ export MYSQLCLIENT_LDFLAGS=`pkg-config mysqlclient --libs` $ pip install mysqlclient

Настройка среды MySQL Python и установка mysql.connector

Чтобы создавать приложения реального мира, для языков программирования необходимо соединение с базами данных. Однако python позволяет нам подключать наше приложение к базам данных, таким как MySQL, SQLite, MongoDB и многим другим.

В этом разделе руководства мы обсудим возможность подключения и настройки среды MySQL в Python и будем выполнять операции с базой данных.

Установка mysql.connector

Чтобы подключить приложение python к базе данных MySQL, мы должны импортировать модуль mysql.connector в программу. Mysql.connector не является встроенным модулем, который поставляется с установкой python. Нам нужно установить его, чтобы он заработал.

Выполните следующую команду, чтобы установить его с помощью установщика pip.

> python -m pip install mysql-connector

Или выполните следующие действия.

1. Загрузите по ссылке исходный код:

2. Извлеките заархивированный файл.

3. Откройте терминал(CMD для Windows) и измените текущий рабочий каталог на каталог с исходным кодом.

$ cd mysql-connector-python-8.0.13/

4. Запустите файл с именем setup.py с помощью python(python3, если вы также установили python 2) с параметром build.

5. Выполните следующую команду, чтобы установить mysql-connector.

На установку mysql-connector для python потребуется некоторое время. Мы можем проверить установку после завершения процесса, импортировав mysql-connector в оболочку python.

Таким образом, мы успешно установили mysql-connector для python в нашей системе.

OSError: mysql_config not found

As part of our Server administration services, Bobcares provides answers to any questions.

Let’s take a closer look at how our expert Support team helped a customer fix this problem.

OSError: mysql_config not found

We received the error “OSError: mysql config not found” when installing the python mysqlclient module with pip.

mySQLdb is a Python interface to MySQL, but it is not MySQL. Also, mySQLdb appears to require the command’mysql_config,’ so we’ll need to install that first.

Most Linux distributions come with Mysql pre-installed. For example, in Debian / Ubuntu, we can use the command to install mysql:-
sudo apt-get install mysql

mysql-config is in a separate package that we can install from:
sudo apt-get install libmysqlclient-dev

There are three ways to install Python drivers/connectors for working with MySQL databases.

MySQL-python
Type the following command to install the MySQL-python package:
pip install MySQL-python

mysql-connector-python
Type the following command to install the mysql-connector-python package:
pip install mysql-connector-python

pymysql
Type the following command to install the pymysql package:
pip install pymysql

Easy solution for the OSError: mysql_config not found

Firstly, we must install the apt-get package.
sudo apt-get install mysql-server
sudo apt-get install libmysqlclient-dev
sudo apt-get install libmariadbclient-dev

Then, we need to install pip package
pip install mysqlclient

Then we’re ready to install any package that has a problem with
pip install the-package-name

[Looking for a solution to another query? We are just a click away.]

To sum up, our Skilled engineers demonstrated how to resolve the error:“OSError: mysql_config not found”
