我是 meanjs 应用程序开发的新手，所以我决定遵循http://www.bradoncode.com/tutorials/mean-stack-tutorial-part-1-setup/上的教程
我已经安装了必要的工具来开始使用下面的命令
sudo npm install -g bower
sudo npm install -g grunt-cli
sudo npm install -g yo
sudo npm install -g generator-meanjs
我已经创建了一个项目目录，但是使用yo meanjs和 sudo yo meanjs命令时，meanjs 应用程序安装总是失败并出现以下错误 。我知道这与root权限有关，请帮助我！
