到了这一步，运行命令行，发现有很多乱码小方格，就是因为系统的主题字体不够全，字体一般有 Powerline、Awesome、Nerd 这里推荐用 Nerd，比较全。

由于 OSX 上有的套件需要作编译后才能使用，所以先得装 Xcode Command Tool
- xcode-select ---install # install xcode command tool
- xcode-select -p # check
先裝 Homebrew
- ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
再安裝 caskroom
- brew install caskroom/cask/brew-cask
启用 caskroom 的字型库管理
- brew tab caskroom/fonts
- brew update
nerd 相关的字型很多，可以挑一個自己喜欢的来装，这里安装 Source Code Pro 版本
- brew search nerd #搜索相关字体
- 这里选择了 source code pro 和 ubuntu 两种字体
  - brew cask install font-sourcecodepro-nerd-font
  - brew cask install font-ubuntu-nerd-font
下载完成后在 iTerm 的 preferences 中设置：
