Solution

Internal script is using python instead of python3. So if your build system doesn't have alias for python3 or python3.x as python, You could meet error like below during running setup.py script.
You can try one of below

1. install "python-is-python3"

sudo apt-get install python-is-python3

2. set alias

Assuming your system has /usr/bin/python3.10

sudo vi ~/.bash_aliases 
alias python=/usr/bin/python3.10
alias python3=/usr/bin/python3.10

After then apply alisa

source ~/.bash_aliases

3. use "update-alternatives"

Assuming your system has /usr/bin/python3.10

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.10 20
