8.52.1. Installation of Flit-Core

Build the package:

pip3 wheel -w dist --no-cache-dir --no-build-isolation --no-deps $PWD

Install the package:

pip3 install --no-index --no-user --find-links dist flit_core

The meaning of the pip3 configuration options and commands:


This command builds the wheel archive for this package.

-w dist

Instructs pip to put the created wheel into the dist directory.


Prevents pip from copying the created wheel into the /root/.cache/pip directory.


This command installs the package.

--no-build-isolation, --no-deps, and --no-index

These options prevent fetching files from the online package repository (PyPI). If packages are installed in the correct order, pip won't need to fetch any files in the first place; these options add some safety in case of user error.

--find-links dist

Instructs pip to search for wheel archives in the dist directory.
