Deprecated backport of asyncio; use the stdlib package instead
Decision gist · record as of 2026-08-14
No. Do not install this package. The maintainers explicitly state it should not be installed. Use the asyncio module from the Python standard library (available since Python 3.4) instead. This package is abandoned, contains no code, and exists only to prevent accidental installation of an outdated backport.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
This is an obsolete backport of the asyncio module that was once needed for Python versions before 3.4. The package now contains no code and exists solely as a placeholder to prevent accidental installation of an outdated distribution. The repository is archived and abandoned.
Since asyncio has been part of Python's standard library since version 3.4 and the package requires Python 3.4 or later, there is no legitimate reason to install this package. The maintainers explicitly recommend using the asyncio implementation that ships with Python instead.
Use it for
- None—this package has no valid use cases; use the standard library asyncio module instead.
- Legacy dependency cleanup: if an old requirements file lists asyncio, remove it and rely on stdlib.
- Identifying outdated backports in a codebase that need to be removed and updated.
