Root Cause

Two packages depend on each other or have circular dependencies that cannot be resolved.

generic

中文

两个包相互依赖或存在无法解决的循环依赖。

Workarounds

  1. 70% success Use pip's resolver with backtracking 
    pip install --resolver backtracking package_a package_b
  2. 80% success Install compatible versions manually 
    pip install package_a==1.0 package_b==2.0

Dead Ends

Common approaches that don't work:

  1. Installing one package first 50% fail

    May still fail due to conflict.

  2. Uninstalling both and reinstalling 30% fail

    Cycle persists.
