Install python on debian

Unlike ubuntu, debian does not provide a python interpreter by default. So we need to install it by ourself.

In this tutorial, we will build the python from source

Get the python source

You can download the python source from their official site.

For example, I download the 3.10.7 with below command

wget https://www.python.org/ftp/python/3.10.7/Python-3.10.7.tgz

tar -xzvf Python-3.10.7.tgz

Build from source

cd Python-3.10.7

# setup configure
./configure --enable-optimizations

# start the build
# The value  -j 2 represents the number of CPU cores that can be used  
sudo make -j 2

# Check it with nproc command.
nproc
# it should returns 2

# install the binary
sudo make altinstall

# if everythin works well. You should be able to run
python3 -V
Python 3.10.7

The -–enable-optimizations flag optimizes the Python binary and executes multiple tests.

Upgrade pip and install package

python3 -m pip install --upgrade pip
python3 -m pip install <module_name>
