The error you’re encountering indicates that pkg-config is not installed on your system, which is necessary for building mysqlclient. pkg-config is used to retrieve information about installed libraries in the system.

To resolve this, you need to install pkg-config and possibly other dependencies required for building mysqlclient. Here’s how you can do it on a Debian-based system like Ubuntu:

  1. Install pkg-config:

    arduino
    sudo apt-get update
sudo apt-get install pkg-config

  2. Install other necessary dependencies for building mysqlclient. These dependencies may vary depending on your system configuration, but common ones include libmysqlclient-dev:

    arduino
    sudo apt-get install libmysqlclient-dev

Once you’ve installed pkg-config and any other necessary dependencies, try installing mysqlclient again using pip:


pip install mysqlclient

This should hopefully resolve the issue. If you encounter any further errors, they might indicate additional missing dependencies, in which case you’ll need to install them as well.
