解决方案

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

无效尝试

常见但无效的做法:

  1. Installing one package first 50% 失败

    May still fail due to conflict.

  2. Uninstalling both and reinstalling 30% 失败

    Cycle persists.
