npm - using stale package data

Question

Whenever I do an npm install, I get a ton of messages about it using stale package data. What does that mean and is it something I need to worry about?

Here's a small example of the warning messages I get with an npm install. In this particular example I just added "npm install @angular/animations@latest --save":

Answer 1

try that and then reinstall all of your project's dependencies

rm ./package-lock.json rm -r ./node_modules npm cache clear --force 

There is a full thread on github about it, since june I think
