How to install create-react-app through terminal

Question

I am installing create-react-app through terminal. I have checked the node.js version is 4.5.0, which is higher than the requirement here. and the version of npm is 2.15.9. Then I type the command npm install -g create-react-app, there came out such error information:

I wondering why I got such errors. Is there anyone who can help me to figure out this problem? Thank you so much!

sudo npm install -g create-react-app

you're running it as a user without root permissions
