Root Cause

The python_requires value has a syntax error, such as an extra space or invalid operator.

generic

中文

python_requires 值存在语法错误，例如多余空格或无效运算符。

Workarounds

  1. 95% success Correct the python_requires string to PEP 440 format 
    python_requires = '>=3.6,<4.0' (no spaces around comma)
  2. 90% success Use a single specifier if possible 
    python_requires = '>=3.6'

Dead Ends

Common approaches that don't work:

  1. Using a list of specifiers 90% fail

    setuptools expects a single string, not a list.

  2. Removing the space after the comma 80% fail

    The error is about the format; a single string with commas is acceptable.
