错误：pip 的依赖解析器目前未考虑所有已安装的包。此行为是以下依赖冲突的根源。 mypackage 1.0 需要 otherpackage<2.0，但您有 otherpackage 2.1，这不兼容。

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. mypackage 1.0 requires otherpackage<2.0, but you have otherpackage 2.1 which is incompatible.

根因分析

已安装的包存在冲突的版本要求，pip 无法自动解决。

English

Installed packages have conflicting version requirements that pip cannot automatically resolve.

解决方案

  1. 90% 成功率 Create a new virtual environment and install compatible versions 
    python -m venv fresh_env && source fresh_env/bin/activate && pip install mypackage==1.0 otherpackage==1.9
  2. 85% 成功率 Use pip-tools to resolve dependencies 
    pip install pip-tools && pip-compile requirements.in && pip-sync requirements.txt

无效尝试

常见但无效的做法:

  1. Running pip install --upgrade mypackage 75% 失败

    Upgrading mypackage may still require the conflicting version of otherpackage.

  2. Ignoring the warning and continuing 60% 失败

    The conflict may cause runtime import errors or unexpected behavior.
