macOS的Homebrew换国内源

搜索了网上的该内容，都告诉如下方法：但是我用了C-shell，所以没有$(brew --repo)变量，实际上该变量就是指向目录：/usr/local/Homebrew。

git -C "$(brew --repo)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git

git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git

git -C "$(brew --repo homebrew/cask)" remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-cask.git

brew update

所以具体过程改成了：

cd /usr/local/Homebrew/
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
cd Library/Taps/homebrew/homebrew-core
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
cd ../homebrew-cask
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git

vi ~/.cshrc ## add the following line 
setenv HOMEBREW_BOTTLE_DOMAIN http://mirrors.ustc.edu.cn/homebrew-bottles

brew update
brew doctor # to check whether everything is OK. source ~/.cshrc

其实所有的配置文件在这些位置，名字是config：

/usr/local/Homebrew/.git
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/.git
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask/.git
