Installation - deprecated warning messages

Ember CLI
1

Hi. I’m a noob to Ember

Ran the npm install -g ember-cli and received the following warnings. Do I need to update the packages?

Thanks Gerard

npm WARN deprecated urix@0.1.0: Please see … npm WARN deprecated resolve-url@0.2.1: …

npm WARN deprecated sane@4.1.0: some dependency vulnerabilities fixed, support for node < 10 dropped, and newer ECMAScript syntax/features added

npm WARN deprecated @babel/polyfill@7.12.1: :rotating_light: This package has been deprecated in favor of separate inclusion of a polyfill and regenerator-runtime (when needed). See the @babel/polyfill docs (@babel/polyfill · Babel) for more information.

npm WARN deprecated core-js@2.6.12: core-js@<3.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Please, upgrade your dependencies to the actual version of core-js.

Hi @Gerard, welcome! In general these warnings are pretty benign, though they can be annoying. Especially if you were just installing ember-cli and this was the result I would just ignore the warnings. NPM can generate a lot of noise and this should eventually get fixed but in the meantime it shouldn’t cause any issues as long as you’re running new enough node and are using newest (or current LTS) version of ember-cli.

Many thanks Dan and much appreciated. Kind regards, Gerard
