解决方案

  1. 85% 成功率 
    pip install 'package-a<2' 'package-b<2'  # after checking compatibility on PyPI
  2. 88% 成功率 
    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. 75% 失败

    Bypasses safety checks, resulting in an inconsistent environment with subtly broken imports at runtime.

  2. 90% 失败

    Does not resolve the underlying version incompatibility between the two packages.
