if the problem is "shasum check failed for",you can try this way .
I found the way to solve this problem on the internet
first ,copy this to the cmd and enter:
npm config set registry http://registry.cnpmjs.org

and then copy this:
npm info underscore
(I am not really good at English.Please forgive me)
finish all of these,you may do something

Closing as resolved – @Q15010417, it sounds like you're behind the Chinese firewall, so switching to the cnpmjs registry is indeed the most likely way to get past these errors, which are caused by incomplete or corrupt downloads of package tarballs. Thanks for your time!
