根因分析

版本说明符包含语法错误，例如缺少逗号或无效运算符，导致 packaging 解析失败。

English

The version specifier contains a syntax error, such as a missing comma or invalid operator, causing packaging to fail parsing.

解决方案

  1. 99% 成功率 
    pip install 'package>=1.0,<2.0'
  2. 90% 成功率 
    pip install 'package~=1.0'
  3. 85% 成功率 
    Refer to PEP 440 for valid version specifier syntax.

无效尝试

常见但无效的做法:

  1. 90% 失败

    Quoting is already correct; the syntax itself is invalid.

  2. 95% 失败

    Newer pip still enforces valid version specifier syntax.

  3. 95% 失败

    Force reinstall does not bypass parsing.
