Root Cause

The version specifier contains a trailing comma or other syntax errors per PEP 440.

generic

中文

版本说明符包含尾随逗号或其他语法错误（根据 PEP 440）。

Workarounds

  1. 95% success Remove the trailing comma 
    Change to '>=1.0,<2.0' (no space after comma)
  2. 90% success Use a comma-separated list without trailing punctuation 
    pip install 'package>=1.0,<2.0'

Dead Ends

Common approaches that don't work:

  1. Adding more spaces around the comma 90% fail

    The trailing comma is the issue, not spacing.

  2. Using semicolon instead of comma 80% fail

    Semicolons are not valid version specifier separators.
