    fixed by updating file `oh-my-zsh.sh`

    omz update

    preferred zsh themes

    ZSH_THEME="random"                                                                         
# Set list of themes to pick from when loading at random                        
# Setting this variable when ZSH_THEME=random will cause zsh to load            
# a theme from this variable instead of looking in ~/.oh-my-zsh/themes/         
# If set to an empty array, this variable will have no effect.

  • brew 切换 node 版本

    现在默认安装的 node 是 13 版本，因为要用 12 版本，进行如下操作

    安装 12 版本

    brew install node@12

    查看所有 node 版本

    brew ls --versions | grep node

node 13.1.0
node@12 12.13.1

    切换为 12 版本

    brew unlink node
rm -f '/usr/local/bin/npm'
rm -f '/usr/local/bin/npx'
rm -rf /usr/local/lib/node_modules
brew link --force node@12
