【YEOMAN】执行yo命令，报EACCES: permission denied, mkdir '/root/.config/configstore'
基础环境：CentOS7、Nodejs6.0之上，yo：1.8.4在执行yo初始化webapp时，报错，错误内容如下：
Error: EACCES: permission denied, mkdir '/root/.config/configstore'
at Error (native)
at Object.fs.mkdirSync (fs.js:916:18)
at Function.sync (/usr/local/lib/node_modules/yo/node_modules/mkdirp/index.js:71:13)

at Module.load (module.js:458:32)
具体操作如下：
# cd /root/.config/
# cd configstore
-bash: cd: configstore: No such file or directory
# mkdir -p /root/.config/configstore
# chmod g+rwx /root /root/.config /root/.config/configstore
