【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 Object.create.all.get (/usr/local/lib/node_modules/yo/node_modules/configstore/index.js:38:13)

    at Object.Module._extensions..js (module.js:550:10)
    at Module.load (module.js:458:32)

具体操作如下：

[root@iZ289zd8c52Z yeomansv]# cd /root/.config/

[root@iZ289zd8c52Z .config]# cd configstore
-bash: cd: configstore: No such file or directory

[root@iZ289zd8c52Z .config]# mkdir -p /root/.config/configstore

[root@iZ289zd8c52Z .config]# chmod g+rwx /root /root/.config /root/.config/configstore
