EXPO CLI ins not getting installed

Expo SDK
1

I am trying to install CLI with following command.

sudo npm install -g exp

I am getting following error everytime :frowning:

shasum check failed for /tmp/npm-14988-e51cd6e6/registry.npmjs.org/_40expo/ngrok/-/ngrok-2.3.0.tgz

My Node is 6.12.0
NPM is 3.10.10

I tried npm cache clean but that did not helped.

Kindly advice.

Following is complete log of my error screen.

Hi, usually this means that your internet is a little weak and things did not download.

Please try again but before you do, perhaps consider updating your version of node.
