pip install specifies the installation directory
pip install will generally have a default installation directory, which can be changed by using thepython -m siteto view it, and of course the default directory can be modified via thepip install --target=path_name package_name
Python defaults to the system installed 2.7
python3 is version 3.8.
USER_BASE and USER_SITE are actually user-defined base paths for enabling Python scripts and dependent installers.
user_site is actually the default installation path of one's site-packages

distutils: When you decide to distribute your module for use by others, distutils provides them with a standard way to install your module on their machines. ("Dist" in "distutils" means to distribute, as in handing out software to others.)

dist-packagesis a Debian-specific convention that also exists in its derivatives, such as Ubuntu.Modules are installed into dist-packages when they are accessed from the Debian package manager at the following location:
as if/usr/lib/python2.7/dist-packages
Since easy_install and pip are installed from a package manager, they also use dist-packages, but they place the packages here:
/usr/local/lib/python2.7/dist-packages
From the Debian Python Wiki:
dist-packages instead of site-packages. third-party Python software installed from Debian packages goes into dist packages instead of site packages. This is to minimize conflicts between system Python and any source Python builds you may have installed manually.
This means that ifYou install Python manually from source, it will use the site-packages directory. This allows you to keep the two installations separate, especially since Debian and Ubuntu rely on the system version of Python for many of their system utilities.
