Root Cause

The package specifies a python_requires constraint that excludes the current Python version.

generic

中文

包指定了 python_requires 约束，排除了当前 Python 版本。

Workarounds

  1. 95% success Use a compatible Python version 
    Install Python 3.9 or later and create a new virtual environment.
  2. 90% success Use pyenv to switch Python versions 
    pyenv install 3.9.0 && pyenv local 3.9.0 && pip install mypackage

Dead Ends

Common approaches that don't work:

  1. Using --ignore-requires-python flag 90% fail

    This flag does not exist; pip enforces python_requires strictly.

  2. Downgrading the package to an older version 70% fail

    Older versions may also have python_requires constraints.
