PyPI httpx2 2.12.0 package httpx2 import compatibility

💡 Result:

The httpx2 package is a fork of the original httpx library, maintained by Pydantic [1]. As of version 2.12.0, the package requires Python 3.10 or newer [2]. Regarding import compatibility, httpx2 is intended to replace httpx [3][2]. To use it, you must update your code to import the package as follows: import httpx2 # Example usage r = httpx2.get('https://www.example.org/') [4] Because httpx2 is a fork with a different package name, simply replacing the package in your environment and changing the import statement in your code is the primary migration path [3][2]. If you have existing dependencies that still rely on the original httpx package and you cannot update them, the library provides an optional utility, httpx2.alias_httpx, which can be called at the application level to make import httpx statements resolve to httpx2 process-wide [5]. This utility is designed for applications only, not for libraries [5]. Additionally, if you are migrating from the original httpx, note that internal components have also been renamed (e.g., httpcore is now httpcore2) and you should update any logging configurations or User-Agent string matching that previously referenced the original names [3][2].

Complete the httpx/httpx2 compatibility migration.

qdrant_client/__init__.py eagerly imports QdrantClient and AsyncQdrantClient. Their import chain reaches modules that still import httpx, while pyproject.toml declares only httpx2. A clean installation can therefore fail with ModuleNotFoundError: No module named 'httpx'.

Retain httpx as a runtime dependency and use a shared compatibility import, or migrate every runtime httpx import to httpx2. Do not rely on the application-level httpx2.alias_httpx utility.

In `@qdrant_client/http/api_client.py` at line 6, The httpx/httpx2 migration is
incomplete, leaving runtime imports inconsistent with the declared dependency.
Update qdrant_client/http/api_client.py and every runtime httpx import to use
httpx2 or a shared compatibility import, and update pyproject.toml to retain
httpx as a runtime dependency if compatibility imports remain; do not use the
application-level httpx2.alias_httpx utility.
