装bootstrap的时候，先用sudo指令装了bower，但是一打 bower isntall bootstrap 就报错：

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：
