Mysqlclient cannot install via pip, cannot find pkg-config name in Ubuntu

I'm new to linux and VM's in general. Im currently trying to install mysqlclient on a clean Ubuntu Jammy 64 (22.4) vbox instance. The following commands are run beforehand:

    sudo add-apt-repository universe
    sudo apt-get install net-tools -y
    sudo apt-get install python3 -y
    sudo apt-get install python3-pip -y
    pip install pkgconfig
    sudo apt-get install pkg-config -y

When I try to run pip install mysqlclient I get the following error:

vagrant@Ctrl-A-EES:~$ pip install mysqlclient
Defaulting to user installation because normal site-packages is not writeable
Collecting mysqlclient
  Using cached mysqlclient-2.2.0.tar.gz (89 kB)

Any suggestions would help greatly! Thanks!

Expected install to resolve without issue. Tried to resolve pkg-config dependency, to no avail.

Solution from FlyingTeller:

sudo apt-get install pkg-config python3-dev default-libmysqlclient-dev build-essential

Fixed the dependency.

For Rocky 9 the following did the trick:

dnf group install "Development Tools"
dnf install python3-devel mysql-devel pkgconfig

pip install mysql-connector mysqlclient

I had to add build-essential and pkg-config to my Dockerfile after upgrading to Python 3.11 from 3.8 and the mysqlclient install started to fail with the same error. This is working for me now.

FROM --platform=linux/amd64 python:3.11-slim as build
...
RUN apt-get update -y
RUN apt-get install pkg-config -y
RUN apt-get install -y python3-dev build-essential
RUN apt-get install -y default-libmysqlclient-dev
...

use this for Debian/Ubuntu

sudo apt-get update
sudo apt-get install gcc libmysqlclient-dev python3-dev

use this for Fedora:

sudo dnf install gcc mysql-devel python3-devel

then run again

pip install mysqlclient

The error you are encountering while trying to install mysqlclient using pip3 is related to missing pkg-config and its inability to find the required dependencies for building the package.

pkg-config fails to find mysqlclient and mariadb libraries, which are needed to build the mysqlclient Python package.

Try these solutions:

  1. sudo apt-get update && sudo apt-get install python3-dev default-libmysqlclient-dev

If the above doesn't work:

  1. you can try installing the mysqlclient library by specifying the paths to the MYSQLCLIENT_CFLAGS and MYSQLCLIENT_LDFLAGS environment variables manually, as suggested in the error message.

sudo MYSQLCLIENT_CFLAGS="-I/usr/include/mysql" MYSQLCLIENT_LDFLAGS="-L/usr/lib/x86_64-linux-gnu -lmysqlclient" pip3 install mysqlclient

NOTE: Replace /usr/include/mysql and /usr/lib/x86_64-linux-gnu with the correct paths to the mysqlclient headers and library files on your system if they are located elsewhere. The provided paths are common for Ubuntu-based systems.

In my case sudo apt install pkg-config was enough to run pip install mysqlclient.
