mac homebrew的用法

与 MacPorts 类似，OS X 下还有款包管理工具为 Homebrew，安装方法也很简单。

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

好了，安装完毕，Homebrew 的使用方法也很简单。

基本用法

• 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

具体的用法可以 man brew。

brew search formula

这里主要说下，brew search formula 时有时会出现

Error: GitHub API rate limit exceeded for ip. See http://developer.github.com/v3/#rate-limiting for details. You may want to create an API token: http://github.com/settings/applications and then set HOMEBREW_GITHUB_API_TOKEN.

提示已经很明确了，按照说明照做，注册个 github 账号，打开页面 http://github.com/settings/applications. 点击 Create new token，填入 Token descrption 后，点击 Create Token

在家目录的 ~/.bash_profile 中添加如下你申请到的 token

if [ -f /usr/local/bin/brew ]; then
    export HOMEBREW_GITHUB_API_TOKEN=xxxxxxxxxx
fi

最后再 . ~/.bash_profile 更新下你的环境变量。

多版本共存

另外一个，安装不同版本的 formula 的技巧，比方要安装不同版本的 htop

$ brew versions htop                        # 显示 htop 的历史版本

其实就是 Homebrew 对 git 分支的灵活应用。

删除 formula 时删除依赖

$ brew remove formula
$ brew rm $(join <(brew leaves) <(brew deps formula))

Homebrew Cask

通过 homebrew cask 来安装 app，首先是安装

$ brew tap caskroom/cask && brew install brew-cask

默认 homebrew cask 安装 app 至 /opt/homebrew-cask/Caskroom 下，并链接到 ~/Applications 目录。

配置下，让 app 链接至 ~/My Applications 下

$ mkdir ~/My Applications
$ touch ~/My Applications/.localized
$ echo 'export HOMEBREW_CASK_OPTS="--appdir=~/My Applications"' >> ~/.bash_profile
$ source ~/.bash_profile

然后随便安装了

$ brew cask search firefox
$ brew cask install firefox
