npm install -g grunt-cli 我得到的消息是下一个：

我不建议使用sudo来安装你的npm（sudo npm install），好像你需要更新你的版本库，我不确定你正在使用的发行版，但是如果你使用debian或者ubuntu，你应该这样做：
sudo apt-get update sudo apt-get install -y python-software-properties python g++ make sudo add-apt-repository ppa:chris-lea/node.js sudo apt-get update sudo apt-get install nodejs
