Source Settings

Installation also need to set the source, setting up the source we can use more smoothly. As for why so many want to set the role of sources, and these sources, please quote reference links at the end of the text.

Replace brew.git:

cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git

Replace homebrew-core.git:

cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core" git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git

Homebrew Bottles source settings:

对于bash用户:

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
source ~/.bash_profile

对于zsh用户:

echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.zshrc
