failed to install python package

[northlaker]

I tried to install a python3 local package. the commands included in the "run-once.sh":

sudo apt install -y python3-pip
sudo pip3 install -y /boot/btp-0.1.0.tar.gz

where btp-0.1.0.tar.gz is the application package (python3) that I'd like to install and is present in the same folder as the "run-once.sh" file (copied together). I assumed the path to the package is /boot/btp-0.1.0.tar.gz as I can see the file in the /boot folder from ssh.

The "python3-pip" module is installed correctly from the above script, as I can run "pip3" once "ssh"ed into the raspberry pi. the same command (sudo pip3 install -y /boot/btp-0.1.0.tar.gz) works in an ssh session.
