装bootstrap的时候，先用sudo指令装了bower，但是一打 bower isntall bootstrap 就报错：
Error: EACCES, permission denied '/Users/narumi/.config/configstore/bower-github.yml'

还想用sudo？然并luan。
bower ESUDO Cannot be run with sudo
借鉴了*上面达人的回答，先chown
sudo chown -R $USER ~/.config/configstore/
然后再 bower install bootstrap 会提示
May bower anonymously report usage statistics to improve the tool over time? 敲个Y or N，回车
然搞定：
