操作之前要先安装且能正常使用ohmyzsh哦！
安装antigen
macos homebrew
brew install antigen
配置antigen
准确来说其实是配置.zshrc
安装完antigen以后获取其路径，然后修改.zshrc，在里面加上如下内容
# 加载antigen
source /opt/homebrew/share/antigen/antigen.zsh #我用brew安装的antigen路径
# 加载oh-my-zsh
antigen use oh-my-zsh
# 安装插件
antigen bundle command-not-found
antigen bundle zsh-users/zsh-syntax-highlighting
antigen bundle zsh-users/zsh-autosuggestions
antigen bundle zsh-users/zsh-completions
# 安装主题
antigen theme robbyrussell
# 应用上述命令
antigen apply
保存以后source一下zshrc
source ~/.zshrc
然后在终端可以看到
➜ /Users source ~/.zshrc
