Root Cause

The setup.py uses Cython extensions but Cython is not installed in the environment.

generic

中文

setup.py 使用了 Cython 扩展，但环境中未安装 Cython。

Workarounds

  1. 95% success 
    pip install Cython
  2. 90% success 
    [build-system] requires = ['setuptools', 'wheel', 'Cython']

Dead Ends

Common approaches that don't work:

  1. 40% fail

    Global install may not be accessible in virtual environments; also may cause version conflicts.

  2. 70% fail

    Setuptools does not include Cython; it must be explicitly installed.
