根因分析

约束文件包含格式错误的版本说明符，例如没有正确空格的逗号分隔列表或无效运算符。pip 的解析器期望特定语法。

English

A constraints file contains a malformed version specifier, such as a comma-separated list without proper spacing or an invalid operator. pip's parser expects specific syntax.

解决方案

  1. 95% 成功率 
    Correct the constraint syntax: use spaces around commas, e.g., 'package>=1.0,<2.0'.
  2. 90% 成功率 
    Validate constraints with pip install --dry-run -c constraints.txt to catch errors early.

无效尝试

常见但无效的做法:

  1. 75% 失败

    May install incompatible versions, leading to runtime errors.

  2. 60% 失败

    If the file is required for the project, ignoring it can break the build.
