Root Cause

Two top-level requirements transitively require incompatible versions of a shared dependency.

generic

中文

两个顶层依赖间接要求共享依赖的不兼容版本。

Workarounds

  1. 85% success 
    pip install pip-tools
pip-compile requirements.in
pip-sync
  2. 80% success 
    pip install "foo>=1.0,<2" "bar>=2,<3"

Dead Ends

Common approaches that don't work:

  1. 75% fail

    Forces installation but leaves a broken dependency graph; imports may fail at runtime.

  2. 80% fail

    Skips dependencies entirely, causing ModuleNotFoundError later.
