Root Cause

The package's metadata specifies a minimum Python version (python_requires) that is higher than the current interpreter version. This is a hard constraint enforced by pip.

generic

中文

包的元数据指定了最低 Python 版本（python_requires），高于当前解释器版本。这是 pip 强制执行的硬性约束。

Workarounds

  1. 98% success 
    Upgrade Python to a version that satisfies the requirement (e.g., install Python 3.10+).
  2. 75% success 
    Find an older version of the package that supports your Python version: pip install 'foo<2.0' (check package release history).

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Bypasses the check but the package may use syntax or features unavailable in the older Python, causing runtime failures.

  2. 95% fail

    Requires manual modification and repackaging; not feasible for installed packages.
