Homebrew can't update solution

Mac has been upgraded to OSX 10.13 High Sierra after installing homebrew in a low version and cannot brew update problem solution

The problem kept occurring... after digging deeper I found that only uninstalling Homebrew and then re-installing it solved this issue. Uninstall Homebrew: /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)" Then re-install it: /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew update again prompts

Already up-to-date. can be solved

PS：

1、Unfortunately you can no longer chown /usr/local in High Sierra. A workaround is to sudo mkdir /usr/local/include and /usr/local/Frameworks if they don't exist, and

sudo chown -R $(whoami) $(brew --prefix)/*
