Mac升级到10.15.1(MacOS Catalina)环境变量不起作用

某天下班手贱，升级了下系统。

最近发现更新flutter很慢，看.bash_profile里面设置了镜像了啊

网上搜了下，发现是系统升级导致的问题：

Apple has changed the default shell to zsh. Therefore you have to rename your configuration files. .bashrc is now .zshrc and .bash_profile is now .zprofile.

就是mac新的系统修改了默认的shell导致的，需要将.bash_profile修改为.zprofile

或者.bashrc ==》.zshrc
