Error npm WARN package json No repository field

Question

I installed Express.js with the following command:

sudo npm install -g express

I get the following warnings:

npm WARN package.json range-parser@0.0.4 No repository field.
npm WARN package.json fresh@0.1.0 No repository field.
npm WARN package.json methods@0.0.1 No repository field.
npm WARN package.json methods@0.0.1 No readme data.
npm WARN package.json cookie-signature@1.0.1 No repository field.
npm WARN package.json send@0.1.0 No repository field.
npm WARN package.json pause@0.0.1 No repository field.
npm WARN package.json bytes@0.2.0 No repository field.
npm WARN package.json github-url-from-git@1.1.1 No repository field.
npm WARN package.json assert-plus@0.1.2 No repository field.
npm WARN package.json ctype@0.5.2 No repository field.

I'm new to Node.js and Express.js. Why do I have the above warnings?

Hello @kartik,

If you are getting this from your own package.json, just add the repository field to it. (use the link to your actual repository):

"repository" : { 
   "type" : "git",
   "url" : "https://github.com/npm/npm.git"
 }

Hope it helps!!
