Pip will no longer install a combination of packages that is mutually inconsistent and if you ask pip to install two packages with incompatible requirements, it will refuse (rather than installing a broken combination, like it did in previous versions). These changes will become the default in pip 20.3, due to be released in October. pip 用户反馈调查分析 PIP TEAM The pip team are considering removing pip search, or changing the way that it works. To help inform our decision, please tell us about your experience using pip search.
