Root Cause

The function canonicalize_name was moved to packaging.utils in newer versions, but the installed packaging library is too old.

generic

中文

函数 canonicalize_name 在较新版本中已移动到 packaging.utils,但安装的 packaging 库太旧。

Workarounds

  1. 95% success

    try: from packaging.utils import canonicalize_name; except ImportError: from packaging.utils import canonicalize_name as _; # handle manually

Dead Ends

Common approaches that don't work:

  1. 40% fail

    Downgrading may break other packages that depend on newer features.

  2. 80% fail

    The function simply does not exist in older versions; no alternative path works.
