Integrity checksum failure while installing API Connect toolkit #apiconnect

Getting error sha1-UhOHSxsj+deaxi0QbjKXDirzcn8= integrity checksum failed when using sha1: wanted sha1-UhOHSxsj+deaxi0QbjKXDirzcn8= but got sha1-208ds/bfbkHrcce1kMfz2sLUPhs=. (627039 bytes) while installing API Connect toolkit.

Node version:- 6.10.3 NPM version:- 5.0.1

What could be the next steps for fixing this issue ?
