brew 常见问题解决

1.如何让brew每次执行前不要自动更新

export HOMEBREW_NO_AUTO_UPDATE=true
或者直接配置 讲上面的命令插入 ~/.bash_profile 
生效 source ~/.bash_profile
如果安装了 zsh可以装到 ~/.zshrc 中

2.brew 常用命令

brew config # 查看现在镜像源
brew search formula # 搜索软件包
brew install formula # 安装软件包
brew remove formula # 移除软件包
brew cleanup formula # 清除旧包
brew list # 列出已安装的软件包
brew update # 更新 Homebrew
brew upgrade # 升级软件包
brew home formula # 用浏览器打开
brew info formula # 显示软件内容信息
brew deps formula # 显示包的依赖
brew server # 启动 web 服务器，可以通过浏览器访问 http://localhost:4567 来通过网页来管理包
brew -h # 帮助
brew versions formula # 列出软件包的版本
brew services list 列出所有再运行的程序
