Support

Do Not use Github Issue Tracker to ask help. OSS Maintainer is not free tech support

When your question looks relating to Python rather than MySQL/MariaDB:

Python mailing list python-list
Slack pythondev.slack.com

Or when you have question about MySQL/MariaDB:

Free threading Python

[!NOTE] The support for Free threading Python is experimental.

Since v2.2.8, free threading is supported when importing the extension module. Therefore, importing MySQLdb does not acquire GIL.

However, this library does not support simultaneous operations on a single Connection object from multiple threads, regardless of free threading, and the behavior in such cases remains undefined.

[!WARNING] Do not use a single Connection object from multiple threads simultaneously.

Install

Windows

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:

$ pip install mysqlclient

macOS (Homebrew)

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="$(brew --prefix)/opt/mysql-client/lib/pkgconfig"
$ pip install mysqlclient

Linux

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:

$ pip install mysqlclient

Customize build (POSIX)

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
