Hi I'm also new to react and I also faced this problem after so many trouble I found solution: Just run in your command prompt or terminal :

npm config set registry http://registry.npmjs.org/

This will resolve your problem. Reference link: http://blog.csdn.net/zhalcie2011/article/details/78726679
