It seems there is an error while trying to install the mysqlclient package from the requirements.txt file. The error message suggests that the mysql_config binary is not found on the system, which is required by the installation process.

To fix this issue, you need to install the MySQL development package that includes the mysql_config binary. Depending on your operating system, you can install it using the following command:

For Ubuntu/Debian:

sudo apt-get install libmysqlclient-dev

For CentOS/Fedora:

sudo yum install mysql-devel

For macOS:

brew install mysql

After installing the MySQL development package, try installing the mysqlclient package again using pip
