我最近升级到了MacOS Catalina，一切似乎都很好。一周后，我继续将Shell更改为zsh。从那时起，无论执行了一次还是多次升级，每个brew upgrade在执行一次且仅一次升级后都以消息zsh: abort brew upgrade结尾。尽管出现中止消息，列表中的第一个升级项目实际上确实得到了升级。
运行brew doctor显示：
% brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!
Warning: Some frameworks can be picked up by CMake's build system and will likely
cause the build to fail. To compile CMake, you may wish to move these
out of the way:
/Library/Frameworks/libcurl.framework
%
我对弄乱系统框架持怀疑态度，但是我继续将其重命名。 brew doctor现在报告Your system is ready to brew.，但是现在brew cleanup现在生成zsh: abort brew cleanup消息。我还想知道，下次系统更新时，libcurl冲突会发生什么。
有人看到过这种行为吗？如果是，解决办法是什么？
