根因分析

依赖关系图包含循环，使得无法满足所有需求。

English

The dependency graph contains a cycle, making it impossible to satisfy all requirements.

generic

解决方案

  1. 80% 成功率 
    pip install package1==1.1 package2==2.1  # versions that don't depend on each other
  2. 70% 成功率 
    pip install package1 package2 --use-deprecated=legacy-resolver

无效尝试

常见但无效的做法:

  1. 60% 失败

    Ignores dependencies entirely, but the cycle remains; runtime errors are likely.

  2. 90% 失败

    The cycle is inherent; order does not resolve it.
