The error "mysqlclientpypy install" usually indicates that you are trying to install the mysqlclient library for Python but are missing necessary dependencies.

To install mysqlclient on Debian/Ubuntu systems, use the following command:

sudo apt-get install python3-dev default-libmysqlclient-dev build-essential pkg-config
For other distributions like CentOS/RedHat, use:

sudo yum install python3-devel mysql-devel
Then, use pip to install mysqlclient:

pip3 install mysqlclient
Double-check the specific dependencies needed for your system and Python version.

another way you can delete mysqliclient in requirements.txt and put the mysqlclient==2.2.4
