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‘ You don‘t have access to this file. at Object.fs.openSync (evalmachine.<anonymous>:432:18) at Object.fs.readFileSync (evalmachine.<anonymous>:289:15) at Object.create.all.get (/usr/local/lib/node_modules/bower/node_modules/configstore/index.js:34:29) at Object.Configstore (/usr/local/lib/node_modules/bower/node_modules/configstore/index.js:27:44) at readCachedConfig (/usr/local/lib/node_modules/bower/lib/config.js:19:23) at defaultConfig (/usr/local/lib/node_modules/bower/lib/config.js:11:12) at Object.<anonymous> (/usr/local/lib/node_modules/bower/lib/index.js:16:32) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32)
还想用sudo？然并luan：
bower ESUDO Cannot be run with sudo
借鉴了stackOverflow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：
