About installer

from the package's own PyPI description — quoted content, verbatim

installer

This is a low-level library for installing a Python package from a wheel distribution. It provides basic functionality and abstractions for handling wheels and installing packages from wheels.

Logic for "unpacking" a wheel (i.e. installation).
Abstractions for various parts of the unpacking process.
Extensible simple implementations of the abstractions.
Platform-independent Python script wrapper generation.

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

A low-level library for unpacking and installing Python packages from wheel distributions, providing abstractions and extensible implementations for the installation process.

No runtime dependencies and a pure-Python wheel distribution make installation frictionless. Active maintenance with recent releases and no known vulnerabilities support reliability.

MIT license permits unrestricted use, modification, and distribution with minimal restrictions, making it suitable for both open-source and commercial projects.

Usage

pip install installer

from installer.sources import WheelSource
from installer.destinations import SchemeDictionaryDestination

# Unpack a wheel to a destination
with WheelSource.from_file('package.whl') as source:
    destination = SchemeDictionaryDestination({})
    source.install(destination, {})

Requires Python 3.10 or later.

Verdict: A well-maintained, zero-dependency wheel installation library with MIT licensing and no security vulnerabilities. Suitable for build tools and package managers needing low-level wheel handling; active development and top-1000 popularity indicate production readiness.

Needs verification

Whether the library is used as a runtime dependency by major packaging tools or primarily as a development/build-time utility.
Performance characteristics when handling large wheels or batch installations.
