Root Cause

install_requires contains an invalid specifier string with stray characters or malformed version operators.

generic

中文

install_requires 包含带有杂散字符或格式错误的版本操作符的无效说明符字符串。

Workarounds

  1. 98% success 
    Use valid PEP 440 specifiers: `install_requires=['bar>=1.0']` (no spaces around operators inside quotes).
  2. 95% success 
    Run `python -c "from packaging.requirements import Requirement; Requirement('bar>=1.0')"` to test each string.

Dead Ends

Common approaches that don't work:

  1. 85% fail

    Older setuptools is stricter; the syntax error remains.

  2. 90% fail

    Breaks runtime dependencies for users.
