Step2: tar xzvf node-v* && cd node-v*

Step3: sudo yum install gcc gcc-c++

Step4: ./configure

Step5: make

Step6: sudo make install

Step7: node --version

I had successfully installed nodejs, I follows this steps from Install Nodejs

Then install npm by running command sudo yum install npm.

Now I am trying to install bower So I run the following command npm install -g bower. But getting the following error. Please tell me how to install bower correctly.
