我在安装nodejs后尝试在centos7上安装bower.要安装nodejs,我按照以下步骤操作

第1步：wget http://nodejs.org/dist/v0.10.30/node-v0.10.30.tar.gz

第2步：tar xzvf node-v *&& cd node-v *

Step3：sudo yum安装gcc gcc-c

Step4：./ configure

第五步：制作

Step6：sudo make install

Step7：node –version

我已成功安装了nodejs,我从Install Nodejs开始执行此步骤

然后通过运行命令sudo yum install npm安装npm.

npm install -g bower.但是得到以下错误.请告诉我如何正确安装凉亭.
