根因分析

pip的解析器在解析依赖时未检查所有已安装的包，导致当某个包需要未安装或不兼容版本的依赖时产生冲突。

English

Pip's resolver does not check the full set of installed packages when resolving dependencies, leading to conflicts when a package requires a dependency that is not installed or is an incompatible version.

解决方案

  1. 创建新的虚拟环境并使用固定版本安装包：`python -m venv venv && source venv/bin/activate && pip install -r requirements.txt`
  2. 使用 `pip check` 识别并手动修复缺失或冲突的依赖，然后安装缺失包：`pip install <missing-dependency>==<compatible-version>`

无效尝试

常见但无效的做法:

  1. 60% 失败

    The resolver behavior is inherent to pip's design and not fixed by version upgrades alone.

  2. 50% 失败

    This can break environment consistency and may reintroduce the same conflicts if requirements are not pinned.
