oh-my-zsh和插件的安装流程

1.安装更新zsh

brew install zsh

2.确保有zsh的情况下 安装oh my zsh

sh-c"$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

3.安装插件zsh-autosuggestions:输入命令时可提示自动补全

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

安装插件zsh-syntax-highlighting:日常用的命令会高亮显示，命令错误显示红色

$ git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

然后编辑vim ~/.zshrc文件，找到plugins配置，增加zsh-autosuggestions插件。默认是 plugins=(git)，如果里面有多个可以用空格分开

plugins=(
         git
         zsh-autosuggestions
         zsh-syntax-highlighting
)

然后执行 source ~/.zshrc 就可以了。
